Installing An Ac Power Supply - Avaya 8400 Manual

Installing an AC power supply

The VSP 8404 supports two field-replaceable 800 W power supplies. One comes with the switch
and you can install a second power supply to provide redundancy and load sharing.
Before you begin
• Remove the power cord before installing or removing the power supply.
Note:
The design of the latch mechanism that secures the power supply enforces this safety
practice.
Procedure
1. Loosen the two screws that secure the power supply cover to the chassis. (Save the power
supply cover for possible future use.)
2. Slide the power supply into the slot.
3. Verify that the power supply is fully seated in the slot. The spring latch should engage and
return to its original position.
Note:
The chassis design prevents an incorrect installation of a power supply. If you insert a
power supply upside down, it will not fully insert.
4. Once you install a power supply, you can connect the AC power cord to the power supply on
the back of the switch, and then connect the cord to an AC power outlet.
