Maintaining the Cisco 6400
Replacing a DC Power Entry Module
Removing a DC Power Entry Module
If you remove a redundant DC PEM, the chassis continues to operate normally. If you plan to remove
the only operating PEM from a chassis, you must first power down the Cisco 6400 system. Refer to the
procedure in the
“Powering Down the System” section on page 5-8
To remove a PEM from the Cisco 6400 chassis:
Step 1
Ensure that the circuit breaker on the DC PEM you are removing is turned Off.
Step 2
Unscrew the retaining screws on the DC PEM faceplate.
Step 3
Grasp the DC PEM by the handle on the faceplate and pull it out of the chassis.
Caution
Always install a filler panel over an empty PEM power bay to protect the connectors from
contamination and to ensure proper air flow.

into the Cisco 6400 without powering down the system.
