Replacing a Power supply
Your server system contains two standard 450-Watt power supplies that are
housed in the rear of the chassis.
The power supplies are numbered 1 and 2, right to left as seen from the rear of
the system. Both power supplies are CRUs and are hot pluggable and redundant.
Each power supply has three status indicators that are listed along with a
description of each in Table 1-6 of chapter 1.
To replace a power supply, perform the following procedures.
1. Observe the safety and ESD precautions listed at the beginning of this
chapter.
3. Unplug the power cord from the AC wall outlet and from the input
receptacle on the rear of the power supply you are removing.
