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.
For instructions on wiring the new PEM, refer to the installation document that
arrived with the PEM, or to the wiring procedure in the Cisco 10005 ESR
Hardware Installation Guide.
Never install an AC power module and a DC power module in the same chassis.
To install a second AC power supply for redundancy:
Make sure the power switch on the new AC power supply is set to standby. (Press
the left side of the power switch.)
Loosen the captive screws and remove the blank cover from the empty power bay.
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
