Chapter 5 Removal and Replacement Procedures
Removing and Replacing the PEM
Removing and Replacing the PEM
This section describes how to remove and install the PEMs for the Cisco 7603, Cisco 7603-S, and Cisco
7606 routers.
The PEM provides an input power connection on the front of the chassis to connect the site power source
to the power supply. In addition to providing an input power connection, the PEM also has an illuminated
power switch (AC-input only), current protection, surge and EMI suppression, and filtering functions.
The PEM on the left (PEM 1) connects the site power source to power supply 1; the PEM on the right
(PEM 2) connects the site power source to power supply 2. See
Figure 5-105 for the location of the PEM;
see Figure 5-106 (Cisco 7603 router), Figure 5-107 (Cisco 7603-S router), and Figure 5-108 (Cisco 7606
router) for the location of the power supplies.
