3.5 Power Subsystem
This section gives a brief description of the power subsystem. Refer to Appendix
C for a detailed discussion.
The power subsystem consists of a power backplane, swappable power supply
modules, and an optional uninterruptible power supply (UPS) module held in
place by a metal rack enclosure. The backplane and the rack allow installation of
up to three 400-watt power supply modules in a load-sharing (across two),
redundant configuration.

Always observe the following ESD (electrostatic discharge) precautions before
installing any system component:
1. Do not remove any system component from its packaging unless you are
ready to install it.
2. Wear a wrist grounding strap before handling electronic components. Wrist
grounding straps are available at most electronic component stores.
DO NOT attempt the procedures in the
following sections unless you are confident of
your capability to perform them. Otherwise,
ask a service technician for assistance.
