Chapter 5 Maintaining the Cisco 10008 Router
Removing and Replacing Field-Replaceable Units
Replacing an AC PEM
Use the following procedure to replace an AC PEM:
Figure 5-29 Setting AC Power Switch to the Off Position
Step 1 Remove the front cover if necessary (see Front Cover Procedures, page 5-4).
Step 2 If your system is configured with redundant PEMs, set only the power switch of the PEM you are
replacing to the off (0) position (the example in Figure 5-29 shows the top PEM in the off position).
Caution Do not power off both AC PEMs in a redundant system, or the system shuts down and all data traffic
stops. Only power off the AC PEM you are replacing.
Step 3 Remove the PEM power cable from its canoe and disconnect it from the AC input power cable.
