Installing a Power
Supply Module
To install a power supply module:
1 Orient the module so that its sides enter the guides on either side of the
chassis slot.
2 Slide the module into the chassis until the face panel is flush with the
enclosure.
3 Secure the screws on either side of the front panel.
4 If a redundant power supply is not installed in the second power supply

Replacing a
Redundant Power
Supply Module
This section describes how to replace a redundant power supply module.
You can replace the redundant power supply without having to turn off
the system (hot-swap). For more information on the operation of the
redundant power supply module, see “Redundant Power Supply” on
page 7-1.

To replace a redundant power supply module:
1 Disconnect the power cord from the power supply.
2 Loosen the screws at the extreme right and left of the power supply, near
the handles (refer to Figure 4-1).
3 Grasp the handles of the redundant power supply you want to replace
and pull them outward. This ejects the power supply.
4 Remove the new power supply from its antistatic bag. Place the old
power supply in the antistatic bag and set it aside in a safe place.
