Chapter 3
Maintaining the Cisco 10005 ESR
Loosen the captive screws on the power supply you are removing and pull the
Step 3
power supply from the chassis using the handle on the faceplate
Figure 3-9
Insert the new AC power supply all the way into the power bay to ensure a secure
Step 4
connection to the midplane. Tighten the captive screws on the power supply.
If you do not immediately install a new power supply, install a blank faceplate
Step 5
over the empty power bay.
Blank faceplates (filler panels) serve three important functions: they prevent
Warning
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.
Connect the power cord to the new power supply.
