Removing and Replacing Field-Replaceable Units
Step 3
Loosen the captive screws on the power supply you are removing and pull the
power supply from the chassis using the handle on the faceplate (
Figure 3-9
).

Removing and Replacing an AC Power Supply
Step 4
Insert the new AC power supply all the way into the power bay to ensure a secure
connection to the midplane. Tighten the captive screws on the power supply.
Step 5
If you do not immediately install a new power supply, install a blank faceplate
over the empty power bay.
Warning
Blank faceplates (filler panels) serve three important functions: they prevent
exposure to hazardous voltages and currents inside the chassis; they contain
electromagnetic interference (EMI) that might disrupt other equipment; and
they direct the flow of cooling air through the chassis. Do not operate the
system unless all cards, power modules, and faceplates are in place.
Step 6
Connect the power cord to the new power supply.
