Using an ESD Wrist Strap to Prevent ESD Damage
Before you touch any switch modules, you must ground yourself to protect the
modules from electrostatic discharge (ESD). You can ground yourself by wearing
an ESD wrist strap connected to a grounded chassis or a grounded rack.
Caution Always handle modules by their carrier edges (typically the covered
bottom, sides, and front of the module) and never touch the circuitry on the
module.
Before you begin You must have a grounding connection close to where you are
installing components in the chassis.
Step 1 Attach or wrap an ESD wrist strap to your arm.

Step 2
Attach the other end of the strap to the grounded chassis in one of the
following ways:
· If the wrist strap has a banana plug on the other end, insert the plug into
the ESD port on the chassis (see the following figure for the location of the
port on the front of the chassis). The chassis has another ESD port on the
rear of the chassis.

Installing or Replacing a Supervisor Module
Installing or Replacing a Supervisor Module
You can install or replace a supervisor module during switch operations so
long as there is another supervisor module installed and operating on the
switch. If you eject the active supervisor from its slot in a chassis with two
supervisor modules, operations automatically switch over to the standby
supervisor module. If you need to replace a supervisor in a chassis with just
one supervisor, you can install the new supervisor in the open supervisor
slot, make the new supervisor active, and remove the other supervisor module.
Note If you remove a supervisor module without replacing it, you must fill the
slot with a blank filler plate to maintain the designed airflow for the
chassis.
Before you begin
Caution The system will shut down when you remove the single supervisor module
in the Cisco Nexus 7702 chassis.
· You must follow ESD protocols, including the following: · You must wear a
grounded ESD wristband (or other personal grounding device) whenever you
handle the electronic modules outside the grounded chassis. · You must carry
electronic modules by only their covered edges or handles. Do not touch their
electronic components. · Whenever a module is outside a grounded chassis,
place it flat on an antistatic surface or in an antistatic bag. Never lean the
module on anything nor place anything else on top of the module nor lean
anything on the module.
· Verify that the chassis is grounded. · Verify that you have the following
tools and equipment:
· ESD wrist strap (or other personal grounding device) · Number 1 Phillips
torque screwdriver
Manual torque screwdrivers are recommended. Be sure to never exceed the
recommended torque setting for the screw that you are working with. ·

· Supervisor 2E (N77-SUP2E=)
Step 1
If you need to remove a supervisor module to open the slot for a new module,
follow these steps (if you already have an open slot, go to the next step):
Note If the slot that you need to open has a blank filler plate, remove the
plate by unscrewing its captive screw and pulling on the handle attached to
the plate to remove the plate, and go to Step 3).

To migrate from Supervisor 2E modules to Supervisor 3E modules, follow these
steps:
Before you begin · Before migrating from Supervisor 2E modules to Supervisor
3E modules, note the following guidelines: · This migration process is
disruptive because the power must be turned off for the switch. · You cannot
mix Supervisor 2E and Supervisor 3E modules in a production environment.
Step 1 Step 2 Step 3 Step 4
Step 5
Insert a USB drive in the usb1 or the slot0 USB port on the active supervisor
2E module. We will use the usb1 port for the steps given below. Format the
drive by using the format command. switch(config)# format usb1
Copy all of the VDC configurations for the switch to the USB drive by using
the copy running-config command. switch(config)# copy running-config
usb1:configuration_file_name vdc-all
Backup the installed licenses for the switch to the USB drive by using the
copy licenses command. switch(config)# copy licenses
usb1:licenses_archive_file_name.tar Note You must use the tar extension for
the archive file. This file will contain all of the license files that were
installed on the Supervisor 2E module.
Copy the Supervisor 3E version of the kickstart, system, and EPLD (optional)

Note This example specifies Cisco NX-OS Release 8.3(1) images. This is the
minimum software release for the Cisco Nexus 7700 Series Supervisor 3E
modules.
Caution Use -s3- images with Supervisor 3E modules. If you use an -s2- image
with a Supervisor 3E module, the supervisor will not boot up. Some examples of
an -s2- image are given below: · n7700-s2-kickstart.8.0.1.bin
· n7700-s2-kickstart.8.1.1.bin

Step 8 Step 9 Step 10 Step 11
Step 12 Step 13
Turn off the power to the switch using the power switch on each power supply.
The Output LED turns off on each power supply and the Status LEDs turn off on
all of the supervisor and I/O modules.
Caution If any of the supervisor or I/O module Status LEDs is turned on
(showing any color), stop at this step until you are able to turn off those
modules.
For each Supervisor 2E module installed in the switch, remove the module and
replace it with a Supervisor 3E module as explained in Installing or Replacing
a Supervisor Module, on page 3.
Caution If the switch has two supervisor modules, ensure that both supervisors
are of the same type. Do not mix Supervisor 2E modules with Supervisor 3E
modules.
Power up the switch by using the power switch on each of its power supplies.
The Output LED on each power supply turns on and eventually turns green when
the power supply is sending power to the switch. The Status LED on each
installed supervisor module also turns on when the module begins to turn on.
The supervisor that becomes active has a green ACTIVE LED (the standby
supervisor module has an amber ACTIVE LED). Remove the USB drive from the
Supervisor 2E module (this drive has the copies of the Supervisor 2E
configuration, license, and software images) and insert it in the USB port on
the active Supervisor 3E module (ACTIVE LED is green). Connect a console to
the active supervisor module as explained in Connecting a Console to the
Switch. If you are setting up the initial configuration for the supervisor
module, the initial setup script will ask you if you want to enforce the
secure password standard. Make your selection, enter your password, and then
confirm the password by entering it again.

Note If the imported configuration file includes configurations for Fabric
Extenders (FEXs) and those modules are not up yet, you will see error messages
for that. If that happens, we recommend that you run the FEX configuration
again after the FEX modules come online. You can verify the status of the FEX
modules and for the associated server-facing interfaces by using the show fex
and show interface brief commands.
Note If you have not inserted the standby supervisor module until now, do not
insert it during this step. Instead, wait until you complete this procedure
before installing the standby supervisor module.

Installing or Replacing Modules, Fan Trays, and Power Supplies Prerequisites
for Nondisruptive Migration from Supervisor 2E Modules (N77-SUP2E) to
Supervisor 3E Modules (N77-SUP3E)
· Do not copy any configurations using the copy running-config startup-config
command or the copy running-config startup-config vdc-all from any other
management session while migration is in progress.
· Do not trigger any EPLD or BIOS upgrades during migration. · Do not trigger
any ISSU during migration. · Do not perform migration from fabric module-2 to
fabric module-3 during the supervisor-2E to
supervisor-3E migration. · Take a backup of the licenses and configuration
before starting the migration procedure. In case of any
failure or loss of licenses and configuration in Supervisor-2E, disruptive
migration has to be done to upgrade to Supervisor- 3E. In such a scenario, all
configurations and licenses have to be applied or installed again. Backup the
installed licenses from the switch to a USB drive by using the copy licenses
command. To view the current licenses installed on the switch, use the show
license command. switch# copy licenses usb1:
· Ensure that there is sufficient power in the chassis before starting the
migration process. In case of a power failure, redundant power supplies can
then take over and migration will not be disrupted.
· Downgrade to supervisor-2E modules from supervisor-3E modules is a
disruptive procedure.
Prerequisites for Nondisruptive Migration from Supervisor 2E Modules
(N77-SUP2E) to Supervisor 3E Modules (N77-SUP3E)
· The minimum supported release for this procedure is Cisco NX-OS Release
8.4(1). If you are using an image older than Cisco NX-OS Release 8.4(1),
upgrade to Cisco NX-OS Release 8.4(1), and then perform nondisruptive
migration from Supervisor 2E modules to Supervisor 3E modules.
· We recommend that you use a console connection to perform the migration
procedure. In case you do not have a console connection and are using an
SSH/Telnet connection, use the terminal monitor command to display all the
syslogs mentioned in the below procedures.
· Back up the running configuration from the current active supervisor module
to the FTP/SFTP/TFTP server, or a USB flash drive.
switch# copy running-config ftp:[//[username[:password]@]server][/path] or
switch# copy running-config usb1:
· Before you initiate the migration procedure, you must first remove QoS
policies and ACLs from interfaces that are in the down state. The clear
inactive-config qos command, that clears inactive configuration, will delete
the port channel policies even if one of the ports in a port channel has
inactive policies. Guidelines for manual policy removal: · During manual
removal, when the interface is part of a port channel, remove the policy map
or access list from the port channel or remove the interface from the port
channel before initiating the migration procedure. · For all other interface
types, please remove the policy map or access list from the interface.
· The migrate sup kickstart

After the supervisor 3E module has been moved to Active mode, non-disruptive migration from supervisor 2E modules to supervisor 3E modules is completed. A console message, SUP3_MIGRATION_COMPLETE, is then displayed.
You can now power down and remove the other supervisor 2E module, and replace it with a Supervisor 3E module. This supervisor 3E module will come up in HA- standby mode.
Case 2: Single Supervisor Migration
To perform non-disruptive migration from Supervisor 2E modules to Supervisor
3E modules in a switch that has only the active supervisor module installed
and there is no standby supervisor module, follow these steps:
Step 1 Step 2
Copy the Cisco NX-OS Release 8.4(1) kickstart and system images to the active
supervisor module bootflash, using an FTP or TFTP server.
switch# copy tftp://tftpserver.cisco.com/n7700/n7700-s3-kickstart.8.4.1.bin

bootflash:system n7700-s3-dk9.8.4.1.bin
Use the migrate sup kickstart
· A message then appears on the console asking for confirmation to continue
the migration procedure. Type Yes on the console prompt to continue with the
migration procedure.
· Configuration commands are now blocked.
· The migrate sup kickstart
· You can use the show modulecommand to display the modules installed in the
switch.

Insert the supervisor 3E module in the other switch supervisor slot, as explained in the Installing or Replacing a Supervisor Module section. When the supervisor 3E module is detected in the standby supervisor slot, a netboot is initiated with the image that is provided by using the migrate sup kickstart
Note
· You have to insert the supervisor 3E module into the switch within a period of 30 minutes after using the
migrate sup kickstart
have not inserted the supervisor 3E module within 30 minutes after using this command, migration is
aborted and you have to use the command again to reinitiate the migration process.
· After the supervisor 3E module is inserted in the slot, a timeout of 45
minutes is triggered for the supervisor 3E module to power up and come online.
If the supervisor 3E module fails to power up and come online at the first
attempt, a retry is initiated every 15 minutes. In case the supervisor 3E
module fails to come online after 3 retries or 45 minutes, you have to remove
the supervisor 3E module and restart the migration process by using the
migrate sup kickstart

After the supervisor 3E module has been moved to Active mode, non-disruptive migration from supervisor 2E modules to supervisor 3E modules is completed. A console message, SUP3_MIGRATION_COMPLETE, is then displayed.
Viewing Migration Status
Use the show logging onboard migration status command on any management
session to display the status of migration. You can use this command during
migration or after migration is complete.
The sample output when this command is used on the supervisor-3E module is as

Installing or Replacing an I/O Module
Before you begin · You must follow ESD protocols, including the following: ·
You must wear a grounded ESD wristband (or other personal grounding device)
whenever you handle the electronic modules outside the grounded chassis. · You
must carry electronic modules by only their covered edges or handles. Do not
touch their electronic components. · Whenever a module is outside a grounded
chassis, place it flat on an antistatic surface or in an antistatic bag. Never
lean the module on anything nor place anything else on top of the module nor
lean anything on the module.
· Verify that the chassis is grounded. · Verify that you have the following
tools and equipment:
· Number 1 Phillips torque screwdriver
Note Manual torque screwdrivers are recommended. Be sure to never exceed the
recommended torque setting for the screw that you are working with.
· Replacement or new I/O module

Installing or Replacing Modules, Fan Trays, and Power Supplies
Installing or Replacing an I/O Module
Note You can replace an I/O module with another I/O module while the switch is operational. To do this action, you must first remove an I/O module from the chassis, and then install a new or replacement I/O module in the newly vacated slot within a couple of minutes to maintain the designed airflow.
Step 1
Open a slot in the chassis for the new I/O module as follows:
Note If you need to remove a blank filler plate from the slot, unscrew the
captive screws on either side of the module and pull the handle on the plate
to remove it from the slot. Continue with Step 2.
a) Disconnect all of the networking cables attached to the front of the I/O
module to be removed. b) Unscrew the captive screw on each side of the module
until the screws are loose and no longer connected to the
chassis (see Callout 1 in the following figure).
Figure 5: Removing an I/O Module
1 Loosen the two captive screws 2 Press the two ejector buttons
3 Two handles spring out part way from the front of the module
c) Press the two ejector buttons on the each side of the module (see Callout 2
in the above figure).
The two handles spring out part way from the front of the module.
d) Fully rotate the two handles away from the front of the module and pull on
them to move the module part way out of its slot.
e) Place one hand under the module to support its weight, grasp the front of
the module with the other hand, pull the module fully out of its slot, and set
the module on an antistatic surface.
Caution Do not touch any electrical circuitry on the removed I/O module.
Handle the module only by its covered surfaces (front and bottom of the
module) and always set the module on an antistatic surface when it is not
inside the chassis.
Step 2
Install the new I/O module in the open slot as follows: a) Unpack the new I/O
module, set it right side up on an antistatic surface (so that you can see the
electrical components
from above the module), and inspect the module for damage.
If anything is damaged, contact your customer representative immediately.

Replacing a Fan Tray
Installing or Replacing Modules, Fan Trays, and Power Supplies
b) Press the two eject buttons (one on each side of the module front) and
rotate the handles away from the front of the module.
c) Without touching any electronic circuitry, grasp the front of the I/O
module with one hand, place your other hand under the module to support its
weight, and lift the module to the slot.
d) Align the back of the module to the guides inside the slot, and slide the
module fully into the slot by pushing on the front of the module.
If you push the module fully into the slot, you seat it onto its connectors
inside the slot and the handles move part way toward the front of the module.
The front of the module should be 1/4 inch (0.6 cm) out of the slot.
e) Simultaneously rotate each of the two handles to the front of the module
until they click.
As you rotate the handles to the front of the module, the module should move
fully into the slot.
f) Verify that the front of the module is even with the fronts of the other
installed I/O modules. If not, press both ejector buttons, pull on the handles
to partly remove the module, and repeat Steps 2d and 2e to reseat the module
in the slot.
g) Screw in the two captive screws (one on each side of the module) to secure
the module to the chassis. Tighten the screws to 8 in-lb (0.9 N·m) of torque.
The Status module LED should be green. If not, see I/O Module LEDs for
information about the LED states.
h) Attach networking cables to the I/O ports.
The LED for each port should be green. If not, see I/O Module LEDs for
information about the LED states.
Replacing a Fan Tray
You can replace a fan tray module during operations so long as there are at
least two other fan tray modules operating in the chassis. We recommend that
you put a switch in fan tray maintenance mode before removing a fan tray. You
can also remove a fan tray in order to replace one of the two fabric modules
installed behind it. When not replacing a fan tray or a fabric module, there
should be three fan trays operating in the chassis.
Note You have up to 72 hours to replace one fan tray as long as the switch
air-inlet temperature does not exceed 86° Fahrenheit (30° C). If the
temperature exceeds 86° Fahrenheit (30° C), the switch will shut down in 3
minutes. If you remove more than one fan tray at a time, the switch can
operate up to three minutes before shutting down. To prevent a shutdown,
remove only one fan tray at a time.
Starting from Cisco NX-OS Release 7.2(0)D1(1), use the hardware fan-tray
maintenance-mode [long | medium | short] command to prepare a switch for fan
tray removal. By default, the fans run at 100 percent speed for approximately
4 minutes to prepare for fan tray removal when the hardware fan-tray
maintenance-mode command is used. Starting from Cisco NX-OS Release 8.1(1), by
default, the fans run at 85 percent speed for approximately 4 minutes to
prepare for fan tray removal when the hardware fan-tray maintenance-mode
command is used.
Use the long keyword to run the fans at 65 percent speed for approximately 9
minutes to prepare for fan tray removal. Use the medium keyword to run the
fans at 75 percent speed for approximately 6 minutes to prepare for fan tray
removal. Use the short keyword to run the fans at 85 percent speed for
approximately 4 minutes to prepare for fan tray removal. For more information
about the hardware fan-tray maintenance-mode, see Cisco Nexus 7000 Series NX-
OS System Management Command Reference.

Replacing a Fan Tray
The fan tray maintenance mode will be cancelled in the following cases:
· If a temperature alarm is present.
· Hot-inlet temperature (Sup inlet temperature >= 30 degrees Celsius)
· Fan-tray is absent.
· Post-cool period (time elapsed after fan tray removal) has crossed 4
minutes.
Note Fan tray maintenance mode is cancelled and fan speed is set to normal if
fan tray migration or replacement is completed within 2 minutes of using the
hardware fan-tray maintenance-mode command. If fan tray migration or
replacement is not completed within 2 minutes, the remaining fan trays run at
85 percent speed for the next 2 minutes, and at 100 percent speed from then
on.
· Pre-cool period (time elapsed before fan tray removal) has crossed 1 hour
and 9 minutes–The fan tray has not been removed since the past 1 hour and 9
minutes during which the switch was ready for fan tray removal.
The following example shows the syslogs that are generated when the fan speed
increases due to a minor temperature alarm:

Installing or Replacing a Fabric Module
The fabric modules are located as follows behind the fan trays on the back
side of the chassis:
· Fabric slots 1 and 2 are behind fan tray slot 1
· Fabric slots 3 and 4 are behind fan tray slot 2
· Fabric slots 5 and 6 are behind fan tray slot 3
When the fan trays are installed, they display the LED states for the fabric
modules installed behind them.
You can install a fabric module during operations so long as there is at least
one other fabric module installed and functioning in the chassis. To install
or replace a fabric module, you must first remove the fan tray that is in
front of the fabric module. If the chassis has fewer than six fabric modules,
leave the empty slots unfilled–the fan tray that you place outside the fabric
modules maintains the designed airflow for the chassis.
Before you begin
· The chassis must be grounded.
· You must be wearing wearing an ESD wrist strap (or other ESD prevention
device) that is connected to the ESD port on the grounded chassis.
· Starting from Cisco NX-OS Release 7.2(0)D1(1), put the switch in fan tray
maintenance mode to prepare the switch for fan tray removal.
Step 1
Remove the fan tray that covers the fabric module that you are replacing by
following these steps:
a) Loosen four captive screws on the fan tray until they are loose and are no
longer connected to the chassis. b) Grab both handles with both of your hands
and pull the bottom of the fan tray out so that its connectors disconnect
from the chassis (see the following figure).

c) After the connectors are free of the chassis connections, pull whole fan
tray off the chassis. d) Set the fan tray down on one of its covered sides
only on an antistatic pad or inside an antistatic bag.
Caution Do not touch the electrical connectors on the back side and do not set
the back side connectors on anything–always set a fan tray down on a covered
side to protect the connectors.
Step 2
If you need to open a fabric slot for the new fabric module, remove a fabric
module as follows: a) With your face at least 12 inches (30 cm) away from the
front of the fabric module, press both ejector buttons on the
front of the module (see Callout 1 in the following figure).
Caution Keep your face away from the front of the fabric module so that the
levers do not hit your face when they spring out from the front of the module.

Replacing Fabric 2 Modules with Fabric 3 Modules
If you are running Cisco NX-OS 8.3(1) or a later release on a Cisco Nexus 7710
switch, you can replace all the Fabric 2 modules with Fabric 3 modules. You
can replace the modules during operations if you replace each module within a
couple of minutes so that the switch can maintain its designed airflow. The
replacement procedure is non-disruptive to switch operations if there is at
least one fabric module installed and operating in the switch while you
replace the other fabric module.
To replace Fabric 2 modules with Fabric 3 modules, follow these steps:
Step 1 Step 2 Step 3
Verify that the switch is running Cisco NX-OS Release 8.3(1) or a later
release.
Replace the Fabric 2 module that is in the lowest numbered fabric slot.
Enter the show module xbar command, as shown in the example below, to display
the types of fabric modules installed in the fabric slots.

Recovery Procedure for Downgrading to Fabric 2 Modules from Fabric 3 Modules
This section describes the steps needed to downgrade from Fabric 3 modules to
Fabric 2 modules if there are issues with the Fabric 3 upgrade.
Scenario 1
If both Fabric 2 and Fabric 3 modules are up in the switch (FAB2_FAB3 mode),
then replace the Fabric 3 modules with the Fabric 2 modules.
Scenario 2
If the switch is loaded with Fabric 3 modules only (FAB3 mode), then migrating
to Fabric 2 is disruptive. The Fabric 2 module will power down when the switch
is in FAB3 mode.
Perform the steps given below to replace FAB3 modules with FAB2 modules when
the switch is loaded with only FAB3 modules:
Step 1 Step 2 Step 3
Step 4 Step 5
Replace one FAB3 module with a FAB2 module. The switch is still in FAB3 mode.
The FAB2 module will be in power down state.
Repeat Step 1 to replace FAB3 modules with FAB2 modules in all slots until a
single FAB3 module is remaining in the switch.
Remove the last FAB3 module. The I/O modules will be powered down due to non-
availability of Stage2 bandwidth.
Insert a FAB2 module in the slot from which the last FAB3 module was removed.
This FAB2 module will power up and all the I/O modules will also power up in
FAB2 mode.

Installing or Replacing a Power Supply in a Switch Chassis
You can install up to eight power supplies of the following types: · 3-kW AC
power supply (N77-AC-3KW) · 3-kW DC power supply (N77-DC-3KW) · 3.5-kW
HVAC/HVDC power supply (N77-HV-3.5KW)
If you leave any power supply slots empty, you must install a blank filler
plate (N77-3KPS-BLANK-H=) in that slot to maintain the designed airflow.
Note The chassis ships with power supplies already installed but you can
optionally remove the power supplies to make the chassis lighter for the
installation.
You follow the same steps to install AC, DC and HVAC/HVDC power supplies into
the switch, but you ground them differently. For an AC and HVAC/HVDC power
supply, you automatically ground it when you connect its power cable to the
power supply and the power source. For a 3-kW DC power supply, you do not
directly connect the power supply to the earth ground.
Before you begin
· The switch chassis must be installed in a cabinet or rack that is secured to
the data center.
You need the following additional tools and equipment:
· Nut driver attachment for Number 1 Phillips-head screwdriver or ratchet
wrench with torque capability (used only for DC power supplies)
· Crimping tool
· For 3-kW DC power supplies, you need four power cables sized to reach the DC
power source or power interface unit (PIU)
· Grounding wire–Size this wire to meet local and national installation
requirements. For U.S. installations, you must use a 6 AWG copper conductor.
For installations outside the U.S., consult your local and national electrical
codes. The length of the grounding wire depends on the proximity of the switch
to proper grounding facilities.
Step 1
If you need to open a power supply slot for another power supply, follow these
steps: Note If you neet to remove a blank filler plate, unscrew its captive
screws and pull it off the chassis. Go to Step 2.
a) Turn off the power for the power supply that you are removing, as follows:
Installing or Replacing Modules, Fan Trays, and Power Supplies 46
Installing or Replacing Modules, Fan Trays, and Power Supplies
Installing or Replacing a Power Supply in a Switch Chassis
1. Ensure that the power switch on the front of the power supply is set to
standby (labelled as 0). The Output LED turns off.
2. Verify that the Output LED turns off. If the LED is still on, return to
Step 1.
3. If you are removing a DC power supply, ensure that the power is turned off
at the power source by turning off the power for that circuit, and verify that
the Input LEDs turn off.
b) If you are removing a power supply, detach the power and ground cables as
follows: · For a 3-kW AC power supply, unplug the power cables that are
attached to the power supply and the power source.
· For a 3-kW DC power supply, open the terminal box, and use a Phillips
screwdriver to remove the power cables from their terminals. Replace the
terminal box cover. Remove the power cables from the power source.
· For a 3.5-kW HVAC/HVDC power supply, release the built-in latch and unplug
the power cable from the power source.
c) Remove the power supply or blank filler plate from the power supply slot as
follows: Note To remove a blank filler plate, unscrew its captive screws and
pull on its handle to remove the plate from the slot.
· For a 3-kW power supply, press its ejector latch to the left, pull the power
supply part way out of the slot by its handle, place your other hand under the
module to support its weight, and pull it fully from the slot.
· For a 3.5-kW HVAC/HVDC power supply, disconnect the power cable from the
power supply by pressing the release button on the power cable, pull the power
supply part way out of the slot by its handle, place your other hand under the
module to support its weight, and pull it fully from the slot.
Step 2
Install the new power supply in the open slot as follows: a) Verify that the
power switch on the front of the new power supply is set to standby (labelled
as 0) and that the power
supply is not connected to any power sources. b) Hold the handle on the power
supply with one hand, place your other hand under the power supply to support
its
weight, and position the power supply with its back end at the open power
supply bay. c) Slide the unit all the way into the power supply bay until one
of the following situations occurs:
· For a 3-kW power supply, the release latch on the front of the power supply
clicks and prevents you from moving the power supply in or out of the chassis.
This action completes the mounting of the power supply on this chassis.
· For a 3.5-kW power supply, the built-in latch secures the power cable to the
power supply.
What to do next · For an AC and HVAC/HVDC (when used with an input AC source)
power supply, you must connect it to an AC power source (see the Connecting a
3-kW AC Power Supply to AC Power Sources and Connecting a 3.5-kW HVAC/HVDC
Power Supply to AC Power Sources topic). The power supply will be
automatically grounded through its power cable. · For a 3-kW DC power supply,
you must connect the power supply to the DC power source (see the “Connecting
a DC Power Supply to DC Power Sources” topic).
Installing or Replacing Modules, Fan Trays, and Power Supplies 47
Connecting a 3-kW AC Power Supply to AC Power Sources
Installing or Replacing Modules, Fan Trays, and Power Supplies
Connecting a 3-kW AC Power Supply to AC Power Sources
You use one power cord to connect a 3-kW power supply to its AC power source
and to ground the power supply. Depending on the power mode that you use for
the switch, you either connect all of the power supplies to one AC power
source or you connect half of the power supplies to one AC power source and
the other half to another AC power source:
· For combined power mode (no power redundancy), you need enough power
supplies to power all switch operations and connect all of the power supplies
to the same AC power source. You can install the power supplies in any open
power supply slot in the chassis.
· For power supply redundancy mode (n+1 redundancy mode), you need enough
power supplies to power all switch operations and one extra power supply that
can replace a failing power supply. You connect all power supplies to the same
AC power source. You can install the power supplies in any open power supply
slot in the chassis.
· For input source redundancy (grid redundancy) mode or full redundancy mode,
you need twice the number of power supplies needed to power the switch
operations. You connect half of the power supplies to one power source for
active power and the other half to another power source for redundant power.
You must ensure that the power supplies on the left side of the chassis (slots
1, 2, 5, and 6) are connected to one grid and that the power supplies on the
right side of the chassis(slots 3, 4, 7, and 8) are connected to the other
grid.
Before you begin
Before you connect power supplies to one or two power sources, ensure all of
the following: · You have receptacles for one or two AC power sources within
reach of the power supply cables. The number of power sources depends on the
power mode to be used for the switch. · Combined power (no power
redundancy)–One AC power source
· Power supply redundancy (n+1 redundancy)–One AC power source
· Input source redundancy (power-grid redundancy)–Two AC power sources
· Full redundancy–Two AC power sources
· The AC power sources are rated as follows: · For North American
installations–20A with 110V or 220V circuits.
· For international installations–size the circuits by local and national
standards.
· The power supply is already installed in the chassis.
· The chassis is connected to an earth ground.
Step 1 Step 2 Step 3
Ensure that the power supply switch located on the front of the power supply is set at standby (labeled as 0). Plug one AC power cable into the power supply, and pull down the retention clip over the plug on the power cable. Plug the other end of the power cable into a AC power source supplied by the data center.

Step 4 Step 5
Note If you are using the combined power mode or power supply redundancy, you
connect the power cables to the same 20-A circuit. If you are using the input
source redundancy mode or full redundancy mode, you connect half of the power
cables to one AC power source and the other half to another AC power source.
Warning To reduce risk of electric shock and fire, take care when connecting
units to the supply circuit so that wiring is not overloaded.
Statement 1018
Warning This product relies on the building’s installation for short-circuit
(overcurrent) protection. To reduce risk of electric shock or fire, ensure
that the protective device is rated not greater than:
250V, 20 A
Statement 1005
Turn the power supply switch from standby to on (from 0 to 1 as labeled on the
power switch). Verify that the power supply is receiving AC power and
outputting DC power by making sure that the INPUT and OUTPUT power supply LEDs
are lit and the FAULT LED is not lit or flashing. For an explanation of all
the power supply LEDs and the conditions that they indicate, see Table D-5.
Note When you first activate the power supply, you can verify the
functionality of the LEDs by checking that each LED turns on for a couple of
seconds.
If the Fault LED is flashing red, turn the power switch to standby (labeled as
0), check the AC power connections on the power supply and the AC power
source, and then turn the power switch back on (labeled as 1). The Input and
Output LEDs for the connected power supplies should be green and the Fault LED
should be off.
Connecting a 3.5-kW HVAC/HVDC Power Supply to AC Power Sources
You use one power cord to connect a 3.5-kW HVAC/HVDC power supply to its AC
power source and to ground the power supply. Depending on the power mode that
you use for the switch, you either connect all of the power supplies to one AC
power source or you connect half of the power supplies to one AC power source
and the other half to another AC power source:
· For combined power mode (no power redundancy), you need enough power
supplies to power all switch operations and connect all of the power supplies
to the same AC power source. You can install the power supplies in any open
power supply slot in the chassis.
· For power supply redundancy mode (n+1 redundancy mode), you need enough
power supplies to power all switch operations and one extra power supply that
can replace a failing power supply. You connect all power supplies to the same
AC power source. You can install the power supplies in any open power supply
slot in the chassis.
· For input source redundancy (grid redundancy) mode or full redundancy mode,
you need twice the number of power supplies needed to power the switch
operations. You connect half of the power supplies to one power source for
active power and the other half to another power source for redundant power.
You must ensure that the power supplies on the left side of the chassis (slots
1, 2, 5, and 6) are connected to one grid and that the power supplies on the
right side of the chassis(slots 3, 4, 7, and 8) are connected to the other
grid.

Installing or Replacing Modules, Fan Trays, and Power Supplies
Before you begin Before you connect power supplies to one or two power
sources, ensure all of the following:
· You have receptacles for one or two AC power sources within reach of the
power supply cables. The number of power sources depends on the power mode to
be used for the switch. · Combined power (no power redundancy)–One AC power
source · Power supply redundancy (n+1 redundancy)–One AC power source · Input
source redundancy (power-grid redundancy)–Two AC power sources · Full
redundancy–Two AC power sources
· The AC power sources are rated as follows: · For North American
installations–20A with 110V or 220V circuits. · For international
installations–size the circuits by local and national standards.
· The power supply is already installed in the chassis. · The chassis is
connected to an earth ground.
Step 1 Step 2 Step 3
Step 4 Step 5
Ensure that the power supply switch located on the front of the power supply
is set at standby (labeled as 0). Plug the AC power cable into the power
supply. The built-in latch secures the power cable to the power supply. You
can disconnect the power cable from the power supply by pressing the release
button on the power cable. Plug or connect the other end of the power cable
into a AC power source supplied by the data center.
Note If you are using the combined power mode or power supply redundancy, you
connect the power cables to the same 20-A circuit. If you are using the input
source redundancy mode or full redundancy mode, you connect half of the power
cables to one AC power source and the other half to another AC power source.
Warning To reduce risk of electric shock and fire, take care when connecting
units to the supply circuit so that wiring is not overloaded.
Statement 1018
Warning This product relies on the building’s installation for short-circuit
(overcurrent) protection. To reduce risk of electric shock or fire, ensure
that the protective device is rated not greater than:
250V, 20 A
Statement 1005
Turn the power supply switch from standby to on (from 0 to 1 as labeled on the
power switch). Verify that the power supply is receiving AC power and
outputting DC power by making sure that the INPUT and OUTPUT power supply LEDs
are lit and the FAULT LED is not lit or flashing. For an explanation of all
the power supply LEDs and the conditions that they indicate, see Table D-5.
Note When you first activate the power supply, you can verify the
functionality of the LEDs by checking that each LED turns on for a couple of
seconds.

If the Fault LED is flashing red, turn the power switch to standby (labeled as 0), check the power connections on the power supply and the AC power source, and then turn the power switch back on (labeled as 1). The Input and Output LEDs for the connected power supplies should be green and the Fault LED should be off.
Connecting DC Power Supplies with Power Sources
Connect each installed DC power supply with a DC power circuit as follows:
Note If you are using combined power mode (no power redundancy) or power
supply (n+1) power mode, connect all of the power supplies to the same power
circuit (grid). If you are using input source (n+n) or full power mode,
connect half of the power supplies (located in slots 1, 2, 5, and 6) to one AC
power circuit and the other half of the power supplies (located in slots 3, 4,
7, and 8) to another AC power circuit.
Caution DC return is isolated from the frame (NEBS DC-I).
Before you begin · The power supplies are installed in the chassis. · A DC
power source is within reach of power cables that will be attached to the
power supplies. · Power cables are available to connect each DC power supply
to the DC power source.
Step 1 Step 2
Step 3
Turn the power switch to standby (labeled 0 on the power switch). Turn off the
power at the circuit breakers for the portions of the DC grid power that you
are connecting to and verify that all of the LEDs on the power supplies are
off.
Warning Before performing any of the following procedures, ensure that power
is removed from the DC circuit.
Statement 1003
Size the power cables to the distance between the power supply and the DC
power grid. If you need to cut the cable, cut it at the end that connects to
the DC power grid, remove 0.75 inch (19 mm) of insulation from the cut ends,
and attach them to the DC power system. Be sure to connect the negative cables
to negative lines and positive cables to positive lines.
Note For all your power connections, if you are using cables with two
different colors, use one color cable for all positive circuits and the other
color for all negative circuits.
Warning Hazardous voltage or energy may be present on DC power terminals.
Always replace the cover when the terminals are not in service. Be sure
uninsulated conductors are not accessible when cover is in place.

Remove the three screws that hold down the safety cover for the terminal box
on the front of the DC power supply and remove the cover (see the following
figure).
Note The terminal box has four slots for four power terminals (ordered as
negative [-], positive [+], positive [+], and negative [-]). Each terminal has
two nuts that you use to fasten a power cable to the terminal.
Figure 14: Removing the Safety Cover for the Terminal Box on a 3-kW DC Power
Supply
Step 5 Step 6
1 Remove three screws from the safety cover.
2 Remove the cover.
Install four cables (two positive and two negative cables) in the four
terminal slots as follows: a) Unscrew the two nuts in each of the four
terminal slots. b) Attach and crimp each lug to the end of each power cable.
c) Attach each cable lug to the two terminal posts in each slot, fasten with
two nuts, and tighten to 40 in-lb (4.5 N·m).
Note For all your power connections, if you are using cables with two
different colors, use one color cable for all positive circuits and the other
color for all negative circuits.
d) Replace the safety cover on the terminal box and fasten with three screws.
Install the four cables from the DC power supply to a DC power source as
follows:
a) If the unconnected end of each power cable is not stripped of its
insulation for the last 0.75 inches (19 mm), use wire strippers to remove that
amount of insulation.
b) Attach the negative cables to the negative terminals of a DC power source,
and attach the positive cables to the positive terminals of the same power
source.
Note If you are using combined power mode or power supply redundancy mode,
connect all the power supplies in the chassis to the same power source. If you
are using input source redundancy mode or full redundancy mode, connect half
the power supplies to one DC power source and the other half of the power
supplies to another DC power source.
Step 7 Step 8
For the powered down circuits connected to the power supplies, turn on the
power at the circuit breaker. The Input 1 (IN1) and Input 2 (IN2) LEDs turn on
each connected power supply.
Turn on the power supply by setting the power switch to 1. The LEDs should
flash and then the Output LED should turn on in addition to the Input LEDs.
