CHAPTER 6 Hardware Maintenance
Replacing Power Supply Modules
The following procedure describes how to replace a Power Supply module. The Power Supply
modules are hot-swappable. Therefore, if you are replacing only one module, you can leave
the second module connected to the power source.
The two Power Supply modules installed in the chassis must be of the same hardware
revision. You can identify the hardware revisions by the location (top or middle) of the
power LED on the front panel, as shown below:

by pulling the power plug out of the electrical wall outlet. Remove the plug at the
other end of the power cord from the power inlet on the Power Supply module.
For DC Power: Disconnect the DC power feed cables from your DC power source.
