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.
Note
Step 5
Verify that the power supply is operational by making sure that the power supply LED is green. For information on what
the power supply LEDs indicate, see the
section.
Removing Power Supplies
You can remove one faulty power supply, while the other one provides enough power to the switch.
Step 1
Holding the plug for the power cable, pull the plug out from the power receptacle on the power supply, and verify that
both the power supply LEDs are off.
If you need to remove an Anderson's Saf-D-Grid power cable connector from a high voltage power supply,
press the tab at the top of the connector and pull the connector out of the power supply.
Note
Step 2
Grasp the power supply handle while pressing the release latch towards the power supply handle.
Step 3
Place your other hand under the power supply to support it while you slide it out of the chassis.
Do not touch the electrical connectors on the back side of the module and prevent anything else from coming
into contact with and damaging the connectors.
Caution
Installing and Removing Fan Modules
This section provides instructions for installing and removing the fan modules for the Cisco MDS 9396T
switch. You can replace one of the two 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.
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 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
operations, all the modules must have the same direction of airflow.
