Preparing the Site

· Temperature Requirements, on page 5 · Humidity Requirements, on page 5 · Altitude Requirements, on page 5 · Dust and Particulate Requirements, on page 6 · Minimizing Electromagnetic and Radio Frequency Interference, on page 6 · Shock and Vibration Requirements, on page 7 · Grounding Requirements, on page 7 · Planning for Power Requirements, on page 7 · Airflow Requirements, on page 8 · Rack and Cabinet Requirements, on page 8 · Clearance Requirements, on page 9
Temperature Requirements
The switch requires an operating temperature of 32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius). If the switch is not operating, the temperature must be between ­40 to 158 degrees Fahrenheit (­40 to 70 degrees Celsius).
Humidity Requirements
High humidity can cause moisture to enter the switch. Moisture can cause corrosion of internal components and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size. The switch is rated to withstand from 5- to 95-percent (nonoperating) and 5- to 90-percent (operating) relative humidity. Buildings in which the climate is controlled by air-conditioning in the warmer months and by heat during the colder months usually maintain an acceptable level of humidity for the switch equipment. However, if the switch is located in an unusually humid location, use a dehumidifier to maintain the humidity within an acceptable range.
Altitude Requirements
Altitude rating is 10,000 ft (3048 m). For China, it is 6,562 ft (2000 m).

Dust and Particulate Requirements

Preparing the Site

Dust and Particulate Requirements
Exhaust fans cool power supplies and system fans cool switches by drawing in air and exhausting air out through various openings in the chassis. However, fans also ingest dust and other particles, causing contaminant buildup in the switch and increased internal chassis temperature. Dust and particles can act as insulators and interfere with the mechanical components in the switch. A clean operating environment can greatly reduce the negative effects of dust and other particles. In addition to keeping your environment free of dust and particles, follow these precautions to avoid contamination of your switch:
· Do not permit smoking near the switch.
· Do not permit food or drink near the switch.
Minimizing Electromagnetic and Radio Frequency Interference
Electromagnetic interference (EMI) and radio frequency interference (RFI) from the switch can adversely affect other devices, such as radio and television (TV) receivers. Radio frequencies that emanate from the switch can also interfere with cordless and low-power telephones. Conversely, RFI from high- power telephones can cause spurious characters to appear on the switch monitor. RFI is defined as any EMI with a frequency above 10 kHz. This type of interference can travel from the switch to other devices through the power cable and power source or through the air as transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI that are emitted by computing equipment. Each switch meets these FCC regulations. To reduce the possibility of EMI and RFI, follow these guidelines:
· Cover all open expansion slots with a blank filler plate.
· Always use shielded cables with metal connector shells for attaching peripherals to the switch.
When wires are run for any significant distance in an electromagnetic field, interference can occur to the signals on the wires with the following implications:
· Bad wiring can result in radio interference emanating from the plant wiring.
· Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the chassis and even create an electrical hazard by conducting power surges through lines into equipment.
Note To predict and prevent strong EMI, you need to consult experts in radio frequency interference (RFI).
The wiring is unlikely to emit radio interference if you use a twisted-pair cable with a good distribution of grounding conductors. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

Cisco Nexus 9232E-B1 NX-OS Mode Switch Hardware Installation Guide 6

Preparing the Site

Shock and Vibration Requirements

Caution

If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse that is caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic switches. You will want to consult experts in electrical surge suppression and shielding if you had similar problems in the past.

Shock and Vibration Requirements
The switch has been shock- and vibration-tested for operating ranges, handling, and earthquake standards.
Grounding Requirements
The switch is sensitive to variations in voltage that is supplied by the power sources. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or cause components to fail. To protect against these types of problems, ensure that there is an earth-ground connection for the switch. You can connect the grounding pad on the switch either directly to the earth- ground connection or to a fully bonded and grounded rack.
When you properly install the chassis in a grounded rack, the switch is grounded because it has a metal-to-metal connection to the rack. Alternatively, you can ground the chassis by using a customer-supplied grounding cable that meets your local and national installation requirements. For U.S. installations, we recommend 6-AWG wire. Connect your grounding cable to the chassis with a grounding lug (provided in the switch accessory kit) and to the facility ground.

Note You automatically ground AC power supplies when you connect them to AC power sources.

Note An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using thread- forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Any paint or other non-conductive coatings shall be removed on the surfaces between the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied before installation.
Planning for Power Requirements
The switch includes two power supplies (1-to-1 redundancy with current sharing) in one of the following combinations:
· Two 2000-W AC power supplies

Cisco Nexus 9232E-B1 NX-OS Mode Switch Hardware Installation Guide 7

Airflow Requirements

Preparing the Site

Note For 1+1 redundancy, you must use two power sources and connect each power supply to a separate power source.
Note Some of the power supply modules have rating capabilities that exceed the switch requirements. When calculating your power requirements, use the switch requirements to determine the amount of power that is required for the power supplies.
To minimize the possibility of circuit failure, make sure that each power- source circuit that is used by the switch is dedicated to the switch.
Airflow Requirements
The switch is positioned with its ports in either the front or the rear of the rack depending on your cabling and maintenance requirements. To identify the airflow options for your switch, see the user-replaceable components in the Overview section of this document. You must have fan and power supply modules that move the coolant air from the cold aisle to the hot aisle in one of the following ways:
· Port-side exhaust airflow–Cool air enters the chassis through the fan and power supply modules in the cold aisle and exhausts through the port end of the chassis in the hot aisle.
· Port-side intake airflow–Cool air enters the chassis through the port end in the cold aisle and exhausts through the fan and power supply modules in the hot aisle.
You can identify the airflow direction of each fan and power supply module by its coloring as follows: · Blue coloring indicates port-side exhaust airflow. · Burgundy coloring indicates port-side intake airflow.
Note To prevent the switch from overheating and shutting down, you must position the air intake for the switch in a cold aisle. The fan and power supply modules must have the same direction of airflow. If you must change the airflow direction for the switch, you must shutdown the switch before changing the modules.
Rack and Cabinet Requirements
You can install the following types of racks or cabinets for your switch: · Standard perforated cabinets · Solid-walled cabinets with a roof fan tray (bottom-to-top cooling)
Cisco Nexus 9232E-B1 NX-OS Mode Switch Hardware Installation Guide 8

Preparing the Site

Clearance Requirements

· Standard open four-post Telco racks
Work with your cabinet vendors to determine which of their cabinets meet the following requirements or see the Cisco Technical Assistance Center (TAC) for recommendations:
· Use a standard 19-inch (48.3-cm), four-post Electronic Industries Alliance (EIA) cabinet or rack with mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992 standard.
· The depth of a four-post rack must be 24 to 32 inches (61.0 to 81.3 cm) between the front and rear mounting rails (for proper mounting of the bottom- support brackets or other mounting hardware).
Also, you must have power receptacles that are located within reach of the power cords that are used with the switch.

Warning

Statement 1048–Rack Stabilization
The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before installation or servicing. Failure to stabilize the rack can cause bodily injury.

Clearance Requirements

Installing the Chassis

Installing the Switch Using the NXK-ACC-KIT-1RU Rack-Mount Kit
To install the switch, you must attach front and rear mounting brackets to the switch, install slider rails on the rear of the rack, slide the switch onto the slider rails, and secure the switch to the front of the rack. Typically, the front of the rack is the side easiest to access for maintenance.

Note You must supply the eight 10-32 or 12-24 screws required to mount the slider rails and switch to the rack.
Before you begin · You have inspected the switch shipment to ensure that you have everything ordered. · Make sure that the switch rack-mount kit includes the following parts: · Front rack-mount brackets (2) · Rear rack-mount brackets (2) · Slider rails (2) · M4 x 0.7 x 8-mm Phillips pan-head screws (10)
· The rack is installed and secured to its location.

Step 1

Install two front rack-mount brackets and the two rear rack-mount brackets to the switch as follows: a) Determine which end of the chassis is to be located in the cold aisle as follows:
· If the switch has port-side intake modules (fan modules with burgundy coloring), position the switch so that its ports will be in the cold aisle.
· If the switch has port-side exhaust modules (fan modules with blue coloring), position the switch so that its fan and power supply modules will be in the cold aisle.

b) Position the front rack-mount bracket and the rear rack-mount bracket so that its screw holes are aligned to the screw holes on the side of the chassis.

Note

You can align the holes in the rack-mount bracket to the holes on the side of the chassis (see the two

ways to mount these brackets on a typical chassis, in following figure). The holes that you use depend

on the requirements of your rack and the amount of clearance required for interface cables (3 inches [7.6

mm] minimum) and module handles (1 inch [2.5 mm] minimum).

d) Repeat Step 1 for the other front rack-mount bracket and the other back- mount bracket on the other side of the switch and be sure to position that bracket the same distance from the front of the switch.

Note

Depending on the chassis depth, the back rack-mount bracket may not fit. In that case the back rack-mount

bracket is not needed.

Step 2 Step 3

If you are not installing the chassis into a grounded rack, you must attach a customer-supplied grounding wire to the chassis as explained in the Grounding the Chassis, on page 19 section. If you are installing the chassis into a grounded rack, you can skip this step.
Install the slider rails on the rack or cabinet as follows:
a) Determine which two posts of the rack or cabinet you should use for the slider rails. Of the four vertical posts in the rack or cabinet, two will be used for the front mount brackets attached to the easiest accessed end of the chassis, and the other two posts will have the slider rails.
b) Position a slider rail at the desired level on the back side of the rack and use 12-24 screws or 10-32 screws, depending on the rack thread type, to attach the rails to the rack (see the following figure). Tighten 12-24 screws to 30 in-lb (3.39 N·m) of torque and tighten 10-32 screws to 20 in-lb (2.26 N·m) of torque.

Step 4

c) Repeat Step 3 to attach the other slider rail to the other side of the rack.
To make sure that the slider rails are at the same level, you should use a level tool, tape measure, or carefully count the screw holes in the vertical mounting rails.
Insert the switch into the rack and attach it as follows: a) Holding the switch with both hands, position the two rear rack-mount brackets on the switch between the rack or
cabinet posts that do not have slider rails attached to them (see the following figure).

b) Align the two rear rack-mount guides on either side of the switch with the slider rails installed in the rack. Slide the rack-mount guides onto the slider rails, and then gently slide the switch all the way into the rack until the front rack-mount brackets come in contact with two rack or cabinet posts.
c) Holding the chassis level, insert screws (12-24 or 10-32, depending on the rack type) in each of the two front rack-mount brackets (using a total of six screws) and into the cage nuts or threaded holes in the vertical rack-mounting rails (see the following figure).

Step 5

d) Tighten the 10-32 screws to 20 in-lb (2.26 N·m) or tighten the 12-24 screws to 30 in-lb (3.39 N·m). If you attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility ground.

Grounding the Chassis
The switch chassis is automatically grounded when you properly install the switch in a grounded rack with metal-to-metal connections between the switch and rack.

Note An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using thread- forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Any paint or other non-conductive coatings shall be removed on the surfaces between the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied before installation.
You can also ground the chassis, which is required if the rack is not grounded, by attaching a customer-supplied grounding cable. Attach the cable to the chassis grounding pad and the facility ground.

Warning

Statement 1024–Ground Conductor
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Warning

Statement 1046–Installing or Replacing the Unit
To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be made first and disconnected last.

Before you begin Before you can ground the chassis, you must have a connection to the earth ground for the data center building.

Step 1 Step 2

Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding wire. We recommend 6-AWG wire for the U.S. installations.
Insert the stripped end of the grounding wire into the open end of the grounding lug. Use a crimping tool to crimp the lug to the wire, see the following figure. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out of the crimped lug.

Starting the Switch

Note This equipment is designed to boot up in less than 30 minutes, dependent on its neighboring devices being fully up and running.
Before you begin · The switch must be installed and secured to a rack or cabinet. · The switch must be adequately grounded. · The rack must be close enough to the dedicated power source so that you can connect the switch to the power source by using a designated power cables. · You have the designated power cables for the power supplies that you are connecting to the dedicated power sources.

Note Depending on the outlet receptacle on your AC power distribution unit, you might need an optional jumper power cord to connect the switch to your outlet receptacle.
· The switch is not connected to the network (this includes any management or interface connections). · The fan and power supply modules are fully secured in their chassis slots.

Step 1 Step 2 Step 3 Step 4
Step 5

For any AC power supply, do the following: a) Using the recommended AC power cable for your country or region, connect one end to the AC power supply. b) Connect the other end of the power cable to the AC power source. Verify that the power supply LED is on and green. Listen for the fans; they should begin operating when the power supply is powered. After the switch boots, verify that the following LEDs are lit:
· On the fan modules, the Status (STA or STS) LED is green. If a fan module Status LED is not green, try reinstalling the fan module.
· After initialization, the switch chassis Status (labeled as STA or STS) LED is green.
Verify that the system software has booted and the switch has initialized without error messages. A setup utility automatically launches the first time that you access the switch and guides you through the basic configuration.

Connecting the Switch to the Network

· Overview of Network Connections, on page 23 · Connecting a Console to the Switch, on page 23 · Creating the Initial Switch Configuration, on page 25 · Setting Up the Management Interface, on page 26 · Connecting Interface Ports to Other Devices, on page 27
Overview of Network Connections
After you install the switch in a rack and power it up, you are ready to make the following network connections: · Console connection–This is a direct local management connection that you use to initially configure the switch. You must make this connection first to initially configure the switch and determine its IP address, which is needed for the other connections. · Management connection–After you complete the initial configuration using a console, you can make this connection to manage all future switch configurations. · Uplink and downlink interface connections–These are connections to hosts and servers in the network.
Each of these connection types is explained in one of the sections that follow.
Note When running cables in overhead or subfloor cable trays, we strongly recommend that you locate power cables and other potential noise sources as far away as practical from network cabling that terminates on Cisco equipment. In situations where long parallel cable runs cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield any potential noise sources by housing them in a grounded metallic conduit.
Connecting a Console to the Switch
Before you create a network management connection for the switch or connect the switch to the network, you must create a local management connection through a console terminal. And then configure an IP address for the switch. You can use the console to perform the following functions, each of which can be performed through the management interface after you make that connection:
· Configure the switch using the command-line interface (CLI).
Cisco Nexus 9232E-B1 NX-OS Mode Switch Hardware Installation Guide 23

Connecting a Console to the Switch

Connecting the Switch to the Network

· Monitor network statistics and errors. · Configure Simple Network Management Protocol (SNMP) agent parameters. · Download software updates.
You make this local management connection between the asynchronous serial port on a supervisor module and a console device capable of asynchronous transmission. Typically, you can use a computer terminal as the console device. On the supervisor modules, you use the console serial port.
Note Before you can connect the console port to a computer terminal, make sure that the computer terminal supports VT100 terminal emulation. The terminal emulation software makes communication between the switch and computer possible during setup and configuration.
Before you begin · The switch must be fully installed in its rack, which is connected to a power source, and grounded. · The necessary cabling for the console, management, and network connections must be available. · An RJ-45 rollover cable provided in the switch accessory kit. · Network cabling is routed to the location of the installed switch.

Step 1
Step 2 Step 3 Step 4

Configure the console device to match the following default port characteristics: · 9600 baud · 8 data bits · 1 stop bit · No parity
Connect an RJ-45 rollover cable to the console port on the switch. You can find this cable in the accessory kit. Route the RJ-45 rollover cable to the console or modem. Connect the other end of the RJ-45 rollover cable to the console or to a modem.

What to do next
You are ready to create the initial switch configuration (see Creating the Initial Switch Configuration, on page 25).

Cisco Nexus 9232E-B1 NX-OS Mode Switch Hardware Installation Guide 24

Connecting the Switch to the Network

Creating the Initial Switch Configuration

Creating the Initial Switch Configuration
You assign an IP address to the switch management interface so that you can then connect the switch to the network.
When you initially power up the switch, it boots up and asks you a series of questions to configure the switch. To connect the switch to the network, you can use the default choices for each configuration except the IP address, which you must provide. You can perform the other configurations later as described in the Cisco Nexus 9000 Series NX-OS Fundamentals Configuration Guide.

Note Know the unique name that is needed to identify the switch among the devices in the network.
Before you begin · A console device must be connected with the switch. · The switch must be connected to a power source. · Determine the IP address and the netmask that is needed for the Management (Mgmt0) interface.

Step 1 Step 2

Power up the switch by connecting each installed power supply to an AC circuit. If you are using the combined or power-supply (n+1) power mode, connect all the power supplies to the same AC circuit. If you are using the input-source (n+n) power mode, connect half of the power supplies to one AC circuit. And connect the other half of the power supplies to another AC circuit. The Input and Output LEDs on each power supply light up (green) when the power supply units are sending power to the switch, and the software asks you to specify a password to use with the switch.
Enter a new password to use for this switch. The software checks the security strength of your password and rejects your password if it is not considered to be a strong password. To increase the security strength of your password, make sure that it adheres to the following guidelines:
· At least eight characters · Minimizes or avoids the use of consecutive characters (such as “abcd”). · Minimizes or avoids repeating characters (such as “aaabbb”). · Does not contain recognizable words from the dictionary. · Does not contain proper names. · Contains both uppercase and lowercase characters · Contains numbers and letters
Examples of strong passwords include the following: · If2CoM18 · 2004AsdfLkj30

· Cb1955S21

Note

Clear text passwords cannot include the dollar sign ($) special character.

Tip

If a password is trivial (such as a short, easy-to-decipher password), the software will reject your password

configuration. Be sure to configure a strong password as explained in this step. Passwords are case-sensitive.

If you enter a strong password, the software asks you to confirm the password. Enter the same password again. If you enter the same password, the software accepts the password and begins asking a series of configuration questions. Until you are asked for an IP address, you can enter the default configuration for each question. Repeat this step for each question until you are asked for the Mgmt0 IPv4 address. Enter the IP address for the management interface. The software asks for the Mgmt0 IPv4 netmask. Enter a network mask for the management interface. The software asks if you need to edit the configuration. Enter no not to edit the configuration. The software asks if you need to save the configuration. Enter yes to save the configuration.

What to do next You can now set up the management interface for each supervisor module on the switch.
Setting Up the Management Interface
The RJ-45 and/or SFP management ports provide out-of-band management, which enables you to use the command-line interface (CLI) to manage the switch by its IP address. You can use one of these ports depending on the cable and connecters that you are using to connect the management interface to the network.
Before you begin · The switch must be powered on. · The switch must be initially configured using a console.

Step 1

Connect the management cable into the management port on the switch. For shorter connections, you can use a cable with RJ-45 connectors. For longer connections, you can use an optical cable with SFP transceivers (LH or SX type).

Note

Use only one of these management ports–the switch does not support the use of both management ports.

Cisco Nexus 9232E-B1 NX-OS Mode Switch Hardware Installation Guide 26

Connecting the Switch to the Network

Connecting Interface Ports to Other Devices

Step 2 Connect the other end of the cable to a 10/100/1000 or SFP port on a network device.

Connecting Interface Ports to Other Devices
After you perform the initial configuration for the switch and create a management connection, you are ready to connect the interface ports on the switch to other devices. Depending on the types of interface ports on the switch, you will need to use interface cables with QSFP28, QSFP+, SFP+, SFP transceivers, or RJ-45 connectors to connect the switch to other devices.
If the transceivers that you are using can be separated from their optical cables, install the transceivers without their cables before inserting the cables into the transceivers. This helps to prolong the life of both the transceiver and cables. When removing transceivers from the switch, it is best to remove the optical cable first and then remove the transceiver.
To determine which transceivers, adapters, and cables are supported by this switch, see the Cisco Transceiver Modules Compatibility Information document.

Replacing Components

· Replacing a Fan Module, on page 29 · Replacing a Power Supply Module, on page 30
Replacing a Fan Module
You can replace a fan module while the switch is operating so long as you perform the replacement within one minute. If you cannot perform the replacement within one minute, leave the original fan module in the chassis to maintain the designed airflow until you have the replacement fan module on hand and can perform the replacement.

Caution

If you are replacing a module during operations, be sure that the replacement fan module has the correct direction of airflow, which means that it has the same airflow direction as the other modules in the chassis. Also, be sure that the airflow direction takes in air from a cold aisle and exhausts to a hot aisle. Otherwise, the switch can overheat and shutdown.
If you are changing the airflow direction of all the modules in the chassis, you must shutdown the switch before replacing all the fan and power supply modules with modules using the other airflow direction. During operations, all of the modules must have the same direction of airflow.

Removing a Fan Module

Caution The fans might still be turning when you remove the fan assembly from the chassis. Keep fingers, screwdrivers, and other objects away from the openings in the fan assembly’s housing.
On the fan module that you are removing, press the two sides of the fan module handle together, and pull on the handles enough to unseat it from its connectors.

Cisco Nexus 9232E-B1 NX-OS Mode Switch Hardware Installation Guide 29

Installing a Fan Module

Replacing Components

Installing a Fan Module
Before you begin · A fan slot must be open and ready for the new fan module to be installed. · You must have a new fan module on hand and ready to install within one minute of removing the original fan module if the switch is operating. · The new fan module must have the same airflow direction as the other fan and power supply modules installed in the switch.

Step 1
Step 2 Step 3

Holding the fan module by its handle, align the back of the fan module (the side with the electrical connectors) to the open fan slot in the chassis.
Slide the fan module into the slot until it clicks in place.
Verify that the Status (STS) LED turns on and becomes green.

Replacing a Power Supply Module
The switch requires two power supplies for redundancy. With one power supply providing the necessary power for operations, you can replace the other power supply during operations so long as the new power supply has the same airflow direction as the other modules in the chassis.
You can replace a power supply with another supported power supply that has the same power source type as the other installed power supply. Additionally, the airflow direction of the power supply must match or conform to the airflow direction of the installed fan modules. For the airflow direction used by the switch, see the coloring of the fan modules.
Removing an AC Power Supply
To remove an AC power supply, you must first disconnect the power cable and then remove the module from the chassis.
Before you begin
· To replace a power supply during operations, you must have a functioning power supply providing power to the switch while you replace the other power supply. If there is only one power supply installed in the switch and you need to replace it, install the new power supply in the open slot and power it up before removing the original power supply.
· Ensure that the chassis is grounded. For grounding instructions, see Grounding the Chassis, on page 19.

Step 1

Pull the power cord out from the power receptacle on the power supply to be removed and verify that the LED turns off.

Note

The LED might be on and amber colored to indicate that the input power has been disconnected.

Replacing Components

Installing an AC Power Supply

Step 2 Step 3

Remove the power supply from the chassis by pushing and holding its thumb latch to the left and pulling the power supply part way out of the chassis. Place your other hand under the power supply to support it while you slide it out of the chassis.
Either place the power supply on an antistatic surface or pack it in its packing materials.

What to do next You are ready to install the replacement power supply.
Installing an AC Power Supply
You can replace one power supply while the other one provides power to the switch.
Before you begin · The power supply that you are installing must be capable of using the same airflow direction as the fan trays installed in the same switch and it must use the same type of power source as the other power supply installed in the same switch.

Note If the power supply that you are replacing has a different color handle than the replacement power supply, verify that it has or will have the same airflow direction as the other modules in the switch.
· An AC power source must be within reach of the power cable that will be used with the replacement power supply. If you are using n+n power redundancy, there must be a separate power source for each power supply installed in the chassis. Otherwise, only one power source is required.
· There must be an earth ground connection to the chassis that you are installing the replacement module. Typically, the chassis is grounded by its metal-to-metal connection with a grounded rack. If you need to ground the chassis, see Grounding the Chassis, on page 19.

Step 1
Step 2 Step 3 Step 4

Holding the replacement power supply with one hand underneath the module and the other hand holding the handle, turn the power supply so that its release latch is on the side and align the back end of the power supply (the end with the electrical connections) to the open power supply slot before carefully sliding the power supply all the way into the slot until it clicks into place.

Note

If the power supply does not fit into the open slot, turn the module over before sliding it carefully into the

open slot.

Test the installation by trying to pull the power supply out of the slot without using the release latch. If the power supply does not move out of place, it is secured in the slot. If the power supply moves, carefully press it all the way into the slot until it clicks in place.
Attach the power cable to the electrical outlet on the front of the power supply. Make sure that the other end of the power cable is attached to the appropriate power source for the power supply.
