Installing an AC Power Supply
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 fabric interconnect and it must use the same type of power source as the other
power supply installed in the same fabric interconnect.
Note
• 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
Procedure
Step 1 Holding the replacement power supply with one hand underneath the module (1 in the following illustration)
and the other hand holding the handle, 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
(2).

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 fabric interconnect.

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