Chapter 4 Removal and Replacement Procedures
Removing and Installing PEMs
Step 13
After confirming all installation steps are correctly completed, safety flags and lockout devices can be
removed, and the input circuits to the supplies can be energized.
Step 14
Use the power switch to turn the power supply on.
Step 15
Verify power supply operation by checking that the power supply front panel LEDs are in the following
states:
•
INPUT OK LED is green
•
FAN OK LED is green
•
OUTPUT FAIL LED is not lit
Removing and Installing PEMs
This section describes how to remove and install the Power Entry Modules (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
Note
The PEM is used on the Catalyst 6503 and Catalyst 6503-E switches only.
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
Figure 4-55
for the location of the PEM; see
Figure 4-56
for the location of the power supplies. 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.
