To install a DC PEM in the Cisco 6400 chassis:
Step 1
Ensure that the circuit breaker on the DC PEM is turned to Off.
Step 2
Align the PEM and insert it into the power bay.
Step 3
Firmly push the PEM all the way into the power bay to ensure that the power connectors mate.
Step 4
Tighten the captive screws on the faceplate of the PEM to secure the PEM to the chassis.
If the chassis is connected to power, turn the circuit breaker on the DC PEM to On. The green POWER
Step 5
LED on the faceplate turns on to indicate that the DC PEM is providing power to the chassis. The
yellow FAULT LED goes out.
If the miswire LED is on, reverse the connections on the DC PEM.
