Installing and Removing a Power Entry Module (PEM)

Warning
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, faceplates, front covers, and rear covers are in place.
1.2.1 Software Configuration
If you are removing the card permanently, update the system configuration using the Cisco 6200
Manager (GUI) or the command line interface (CLI). For instructions, see

The power bays are located at front of the chassis, near the top. The bay on the left is wired to power
circuit A; the bay on the right is wired to power circuit B. (The circuits are identified at the power
terminals on the backplane.)
It is not necessary to disconnect power before inserting a PEM into the Cisco 6200 chassis. Follow

Blank faceplates and cover panels serve three important functions: they prevent exposure to
Ensure that the circuit breaker on the PEM is turned to OFF (0).
Use a Phillips screwdriver to remove the front panel that partially covers the power bays.
Two Phillips-head quarter-turn fasteners are recessed into the face of the panel; insert the
screwdriver and turn the fastener 90 degrees in either direction to release it.
Engage the sheet-metal carrier that forms the top of the PEM with the brackets on each
side of the power bay. (See Figure 2.)
Firmly push the PEM all the way into the power bay to ensure that the power connectors
mate.
Tighten the captive screw 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 PEM to ON. A green
LED on the faceplate comes on to indicate that the PEM is providing power to the chassis.
Replace the front panel and use a Phillips screwdriver to fasten it in place. You can look
through the rectangular opening in the panel as you engage the fasteners. Turn the
fastener 90 degrees in either direction to secure it.
