Fan Modules
The fan modules have a fixed handle for insertion and removal from the chassis. The switch requires a minimum of two operating fan modules to prevent automatic shutdown. It supports up to four fan modules. This provides redundancy for uninterrupted operation in the event of fan module failure. The fan modules are hot-swappable to also allow swapping out of a fan module during operation for uninterrupted operation. During a fan module replacement, the internal airflow through the chassis is changed. If the internal airflow is disrupted for too long, the preset temperature thresholds will be exceeded and the system will automatically shut down to prevent permanent damage.
Figure 4: Fan Module

To facilitate different data center cooling configurations of hot or cold aisles and racks, there are two models of fan modules. The first type has airflow with port-side intake and exhaust at the rear of the chassis. The second type has airflow in the opposite direction, that is, rear-chassis intake and port-side exhaust. The airflow direction is denoted on each fan module as follows:
· Red–Port-side intake airflow · Blue–Port-side exhaust airflow
For more information on installing and removing fan modules, see Installing and Removing Fan Modules, on page 35.
Power Supplies
The Cisco MDS 9148T Switch PSUs have an unswitched power receptacle, a PSU status LED and a handle for insertion and removal of the PSU from the chassis. The Cisco MDS 9148T Switch requires a minimum of one operating PSU. It supports up to two PSUs. This provides redundancy for uninterrupted operation in

Preinstallation Guidelines

Preinstallation Guidelines
Airflow Considerations
The switch comes with fan modules and power supply units that have either port-side intake or port-side exhaust airflow for cooling the switch. If you are orienting the switch with the FC ports facing a cold aisle, make sure that the switch has a port-side intake fan and power supply modules with red colorings. If you are orienting the switch with the fan and power supply modules facing a cold aisle, make sure that the switch has port-side exhaust fan and power supply units with blue colorings. All fan modules and power- supply modules must have the same direction of airflow.
Connection Guidelines for AC-Powered Systems
To connect to the Cisco MDS 9396T switch AC power supply units to the site power source, follow these guidelines:
· For power redundancy, each power supply should be connected to a separate power feed (at a minimum, separate branch circuits).
· Circuits should be sized according to local and national codes.
· The AC power receptacles that are used to power the chassis must be the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth ground in the service equipment.
Installation Guidelines
Follow these guidelines when installing the Cisco MDS 9148T switch:
· Each new switch requires a license. See the Cisco MDS 9000 Family NX-OS Licensing Guide for instructions on installing a license.
· Plan your site configuration and prepare the site before installing the switch.
· Ensure that there is adequate space around the switch to allow for servicing the switch and for adequate airflow. The airflow requirements are listed the Technical Specifications, on page 49 section.
· Ensure that you are positioning the switch in a rack so that it takes in cold air from the cold aisle and exhausts air to the hot aisle. For more information, see the Airflow Considerations, on page 21 section.
· Ensure that the air-conditioning meets the heat dissipation requirements listed in the Technical Specifications, on page 49 section.
· Ensure that the cabinet or rack meets the requirements listed in the Cabinet and Rack Installation, on page 13 section.
· Ensure that the chassis is adequately grounded. If the switch is not mounted in a grounded rack, we recommend that you connect both the system ground on the chassis and the site power ground to an earth ground.
· Ensure that the site power meets the power requirements listed in the Technical Specifications, on page 49 section. If available, you can use an uninterruptible power supply (UPS) to protect against power failures.

Cisco MDS 9148T Fibre Channel Switch Hardware Installation Guide 21

Unpacking and Inspecting the Switch

Installing the Cisco MDS 9148T Switch

Caution Avoid UPS types that use ferro-resonant technology. These UPS types can become unstable with systems such as the Cisco MDS 9000 Series, triggered by substantial current draw fluctuations due to fluctuating data traffic patterns.
· Ensure that electrical circuits are sized according to local and national codes. For North America, the 650 W power supplies require a 15 A circuit. If you are using a 200 or 240 VAC power source in North America, the circuit must be protected by a two-pole circuit breaker.
Caution To prevent loss of input power, ensure that the total maximum loads on the circuits supplying power to the switch are within the electrical current ratings for circuit for wiring and breakers.
Unpacking and Inspecting the Switch
Caution When handling switch components, wear an ESD strap and handle modules using only the carrier edges.
Tip Retain the shipping container in case the chassis has to be shipped in the future.
Note The switch is thoroughly inspected before shipment. If any damage occurs during transportation, or if any item is missing, contact your customer representative immediately. If you purchased Cisco support through a Cisco reseller, contact the reseller directly. If you purchased support directly from Cisco, contact Cisco Technical Support.
To inspect the shipment, follow these steps: 1. Compare the shipment to the equipment list provided by your customer service representative and verify
that you have received all items, including the following: · Grounding lug kit · Rack-mount kit · ESD wrist strap · Cables and connectors · Optional items, if any, ordered
2. Check for damage and report any discrepancies or damage, to your customer service representative. Have the following information ready: · Invoice number of shipper (see packing slip)
Cisco MDS 9148T Fibre Channel Switch Hardware Installation Guide 22

Installing the Switch
This section describes how to use the rack mount kit to install the Cisco MDS 9148T switch into a cabinet or rack that meets the requirements described in the Cabinet and Rack Requirements, on page 13 section.
Installing the Switch in a 4-Post Rack
To install the switch, you must attach the front and rear mounting guides to the switch, install the slider rails on the rear of the rack, slide the switch into the slider rails, and secure the switch to the front of the rack. Typically, the front of the rack is the side that is easiest to access for maintenance.
Before you begin · Inspect the switch shipment to ensure that you have everything you ordered. · Make sure that the switch rack-mount kit includes the following parts:

Cisco MDS 9148T Fibre Channel Switch Hardware Installation Guide 24

Installing the Cisco MDS 9148T Switch

Installing the Switch in a 4-Post Rack

· Rack-mount brackets (2)
· Rack-mount guides (2)
· Slider rails (2)
· M4 x 0.7 x 8-mm Phillips countersink screws (12)
· The rack is installed and secured to its location.
· Determine how you want to set up your switch: 1. Determine which end of the chassis is to be located in the cold aisle as follows: a. If the switch has port-side intake modules (fan modules and power supply units with red coloring), position the switch so that its ports are in the cold aisle.
b. If the switch has port-side exhaust modules (fan modules and power supply units with blue coloring), position the switch so that its fan modules and power supply units are in the cold aisle.
2. Determine which way the chassis should slide in and out of the rack–port- side entry first or rear-side entry first. You might consider whether the front or back of the rack provides better clearance for maneuvering the chassis in and out during installation and servicing. The end that needs to enter the rack first requires the guides and the other end the brackets.

Step 1

Install two rack-mount brackets to the switch as follows:
a. Position a rack-mount bracket so that three of its screw holes are aligned to the screw holes on the side of the chassis. You can align any three of the holes in the rack-mount bracket to three of the screw holes on the side of the chassis. The holes that you use depend on the requirements of your rack and the amount of clearance. For more information on clearance, see the General Requirements for Cabinets and Racks, on page 13.
b. You can install the rack-mount bracket either at the front or rear of the chassis. The choice is determined by which end of the chassis will be inserted into the rack first. If the rear end of the chassis is to be inserted first, then mount the brackets on the front of the chassis, and vice versa.

Grounding the Switch

Step 4

If you have attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility ground.

Grounding the Switch
The switch chassis is automatically grounded when you install the switch properly in a grounded rack with metal-to-metal connections between the switch and rack. Alternatively, you can ground the chassis (this is required if the rack is not grounded) by attaching a customer-supplied grounding cable to the chassis grounding pad and the facility ground.
Warning This equipment must be grounded. 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. Statement 1024

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Step 1 Step 2
Step 3

Use a wire-stripping tool to remove approximately 0.75 in. (1.9 cm) of the covering from the end of the grounding wire.
Insert the stripped end of the grounding wire into the open end of the grounding lug, and use a crimping tool to crimp the lug to the wire. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out of the crimped lug.
Remove the label covering the grounding pad on the chassis. Secure the grounding lug to the chassis grounding pad with two M4 screws, and tighten each screw to 11.5 to 15 in-lb (1.3 to 1.7 N·m) of torque.

Installing Power Supply Units
You can replace one power supply unit (PSU) while the other one provides power to the switch.
Before you begin · To implement n+n redundancy, each PSU must be connected to a separate power feed. Otherwise, only one power feed is required.
Cisco MDS 9148T Fibre Channel Switch Hardware Installation Guide 34

Installing the Cisco MDS 9148T Switch

Removing Power Supply Units

· There must be an earth ground connection to the chassis to which 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 Switch.

Step 1
Step 2 Step 3 Step 4
Step 5

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

Note

If the PSU does not fit into the slot opening, turn the unit over and try again.

Test the installation by trying to pull the PSU out of the slot without using the release latch.
If the PSU does not move out of place, it is secured in the slot. If the PSU 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 PSU.
Make sure that the other end of the power cable is attached to the appropriate power feed for the PSU. If the power feed has a switch, slide it to the On position.

Note

Depending on the outlet receptacle on your power distribution unit, you might need the optional jumper

cable to connect the switch to your outlet receptacle.

Verify that the PSU is operational by making sure that the PSU LEDs are both green. For information on what the PSU LEDs indicate, see the LEDs, on page 8 section.

Removing Power Supply Units
You can remove one faulty PSU, while the other one provides enough power to operate the switch.

Step 1
Step 2 Step 3

Holding the plug for the power cable, pull the plug out from the power receptacle on the PSU, and wait until both the PSU LEDs are off.
Grasp the PSU handle while pressing the release latch towards the handle.
Place your other hand under the PSU to support it while you slide it out of the chassis.

Caution

Do not touch the electrical connectors on the back side of the unit and prevent anything else from coming into contact with and damaging the connectors.

Installing and Removing Fan Modules
This section provides instructions for installing and removing the fan modules for the Cisco MDS 9148T switch.
You can replace one of the four fan modules even when the switch is operating so long as you perform the replacement within one minute of removing the old fan module. 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.

Cisco MDS 9148T Fibre Channel Switch Hardware Installation Guide 35

Installing a Fan Module

Installing the Cisco MDS 9148T Switch

Caution

If you are replacing a module during operation, 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 sends it out to a hot aisle. Otherwise, the switch can overheat and shut down.
If you are changing the airflow direction of all the modules in the chassis, you must shut down the switch before replacing all the fan and power supply modules with modules using the other airflow direction. During operation, all the modules must have the same direction of airflow.

Installing a Fan Module
To install a new fan module, follow these steps:
Before you begin · 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. All of these modules must have either red coloring (port-side intake airflow) or blue coloring (port-side exhaust airflow).
· Remove any blank plate or existing fan module from the fan slot.

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 fan module bay until it clicks into place.
Verify that the Status LED turns on and becomes green. For more information on what the LEDs indicate, see the LEDs, on page 8.

Removing a Fan Module
The fan module is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damaging the system.

Caution

The Cisco MDS 9000 Series Switches have internal temperature sensors that can shut down the system if the temperature within the chassis exceed certain safety thresholds. To accurately monitor the system temperature, the temperature sensors require sufficient airflow through the chassis. In the event that a fan module is removed from the chassis and the airflow is reduced, the system will bypass the temperature sensor information and shut down after five minutes to prevent undetected overheating. However, the switches will shut down sooner if the major temperature threshold is exceeded.

Connecting to a Fibre Channel Port
The Fibre Channel ports in the Cisco MDS 9148T switch are compatible with FC LC-type fiber-optic SFP+ transceivers and cables (see the Removing and Installing Cables into SFP Transceivers, on page 42 section). You can use these ports to connect to the SAN or for in-band management. For information about configuring the switch for in-band management, see the Cisco Fabric Manager Fundamentals Configuration Guide or the Cisco NX-OS Fundamentals Configuration Guide. Each transceiver must match the transceiver at the other end of the cable, and the cable must not exceed the stipulated cable length for reliable communications. SFP+ transceivers can be ordered either separately or with the Cisco MDS 9148T switch.
Warning Class 1 laser product. Statement 1008
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051
Note Wear an ESD wrist strap connected to the chassis when handling transceivers. Keep optical connectors covered when not in use, and do not touch connector ends. The fiber-optic connectors must be free of dust, oil, and other contaminants.
Removing and Installing Cables into SFP Transceivers
Caution To prevent damage to the fiber-optic cables, do not place more tension on them than the rated limit and do not bend to a radius of less than one inch (2.5 cm) if there is no tension in the cable, or two inches (5 cm) if there is tension in the cable.

Maintaining SFP Transceivers and Fiber-Optic Cables

Step 2 Step 3
Step 4 Step 5

Remove attached fibre-optic cables, if any. For more information, see the Removing a Cable from an SFP Transceiver, on page 43 section. Remove the transceiver from the port:
· If the transceiver has a Mylar tab latch, gently pull the tab straight out (do not twist), and then pull the transceiver out of the port.
· If the transceiver has a bale-clasp latch, open the clasp by pressing it downwards, and then pull the transceiver out of the port.
Insert a dust cover into the cable-end of the transceiver and place the transceiver on an antistatic mat or into a static shielding bag. Protect the FC port by inserting a clean dust plug if another transceiver is not being installed.

Maintaining SFP Transceivers and Fiber-Optic Cables
SFP transceivers and fiber optic cables must be kept clean and dust-free to maintain high signal accuracy and prevent damage to the connectors. Attenuation (loss of light) is increased by contamination. Therefore, attenuation should be kept below 0.35 dB. Follow these maintenance guidelines:
· SFP transceivers are static-sensitive. To prevent ESD damage, wear an ESD- preventive wrist strap that is connected to the chassis while handling transceivers.
· Do not remove and reinsert a transceiver more often than necessary. Repeated removals and insertions can shorten its useful life.
· Keep all optical connections covered when not in use. If they become dusty, clean them before using in order to prevent dust from scratching the fiber- optic cable ends.
· Do not touch the ends of connectors. This prevents fingerprints and other contamination of the connectors. · Inspect cables before installation for dust and damage. If damage is suspected, clean the ends and check
for excessive light loss with a light meter.
Powering Up the Switch
This section provides instructions for powering up the switch and verifying component installation.
Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the switch.

Note Do not connect the MGMT ETH0 port to the LAN until the initial switch configuration has been performed through the console connection. For instructions on connecting this port, see the Connecting the Management Ports, on page 42 section.

Cisco MDS 9148T Fibre Channel Switch Hardware Installation Guide 45

Powering Up the Switch

Connecting the Cisco MDS 9148T Switch

To power up the switch and verify hardware operation, follow these steps:

Step 1 Step 2
Step 3 Step 4 Step 5 Step 6 Step 7 Step 8
Step 9

Verify that sufficient PSUs and fan modules are installed. Plug the power cables into the power supplies and arrange the cables so that they cannot be accidentally pulled out.

Note

Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper

power cord to connect the switch to your outlet receptacle.

Connect the other end of the power cables to the site power outlets that have the required power specification. Ensure that the switch is adequately grounded, as described in the Grounding the Switch, on page 31 section. Connect a terminal device to the serial console port. For more information, see the Connecting the Console Port, on page 40 section. If using Power On Automatic Provisioning (POAP), insert the USB stick with the required files into the USB port. Turn the site power outlet switches to On. The switch boots automatically. Listen for the fans; they should begin operating as soon as the switch is powered on.

Note

Do not operate the switch without a functioning fan module, except briefly during the fan module

replacement procedure. Cisco MDS 9000 Series Switches can operate for only a few minutes without any

functioning fan modules before they begin to overheat.

Verify that the LED behavior is as follows when the switch has finished booting:

· Fan status LED is green.

· Both LEDs on each PSU are green.

· The switch status LED is green. If this LED is orange or red, it indicates that one or more environmental monitors is reporting a problem.

· The Ethernet port link LEDs should not be On unless the cable is connected.

Note

The LEDs for the Fibre Channel ports remain orange until the ports are enabled, and the LED for the

management port remains Off until the port is connected.

Step 10
Step 11 Step 12 Step 13

If a component is not operating properly, try removing and reinstalling it. If it still does not operate correctly, contact your customer service representative for a replacement.

Note

If you purchased Cisco support through a Cisco reseller, contact the reseller directly. If you purchased

support directly from Cisco, contact Cisco Technical Support.

Verify that the system software has booted and the switch has initialized without error messages. If any problems occur, see the Cisco MDS 9000 Series System Messages Guide. If you cannot resolve an issue, contact your customer service representative.
