Installing A Power Supply - Avaya 8400 Manual

3. Apply gentle pressure anywhere on the faceplate to fully insert the module, and then screw
the module in to ensure a good connection and to secure it to the chassis.
The levers are in the position shown when the module is inserted into the chassis. If you
have to remove a module, loosen the two screws that secure the module to the chassis and
then rotate the extraction levers up to eject the module. Remove the module, and then either
install another module or replace the module bay cover
Important:
You must have either a module or a module bay cover in each bay to ensure proper
ventilation. Leaving a module bay unpopulated or uncovered impairs the ability of the
fans to cool the chassis.

Installing a power supply

The VSP 8404 ships with a power supply, but it is not installed in the chassis. Refer to the following
procedures to install a power supply:
• Installing an AC power supply
• Installing a DC power supply
There are two power supply slots (PSU1 on top and PSU2 on the bottom).
• If you only have one power supply, you can install it in either PSU1 or PSU2.
• If you install a second power supply, neither one acts as a primary power supply. The two
power supplies load share equally.
