Chapter 1 Product Overview
Cisco 6260 System Overview
Note The PEMs reside at the bottom of the chassis, and they are installed and accessed from the
front (see Figure 1-1 for the location of the PEM in the Cisco 6260 chassis). Each PEM is
held in place by the overhanging lip of the fan tray above it. You must remove the fan tray
before you can remove the PEM.
To turn off a Cisco 6260 that has two PEMs, you must flip the circuit breakers on both PEMs
to the OFF (0) position.
The Cisco 6260 can be ordered with only one PEM installed, and with a blank faceplate
installed in place of a second PEM.
Figure 1-23 shows a close-up of the PEM faceplate.
