The AC PEM supports online insertion and removal (OIR), so you can remove and
install the PEM while the system remains powered on without presenting an
electrical hazard or damage to the system. This feature lets you replace the AC
PEM while the system maintains all routing information and ensures session
preservation.
Although an AC PEM supports OIR and can be replaced without interruption to
system operation, do not operate the system without the PEM for more than a few
minutes.
Refer to Figure 5-6 and use the following procedure to remove and replace an AC
PEM.
Power off the faulty PEM.
