Removing and Installing the Power Entry Modules (PEMs)

This section describes how to remove and install the PEMs for the Catalyst 6503 and Catalyst 6503-E
switches. There are three PEM models:
950 W AC-input PEM—PEM-15A-AC
1400 W AC-input PEM—PEM-20A-AC+
950 W DC-input PEM—PEM-DC/3
The PEM is used on the Catalyst 6503 and Catalyst 6503-E switches only.
Note
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.
See
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.
