DC-Input PEM Terminal Block Screws
Step 4
Connect the DC-input wires to the terminal block in the following order:
•
Negative (–)
•
Positive (+)
Note
For a Cisco 7603-S router with 1500W DC power supply, the size of the holes on the PEM into which
the DC wires are input, is 0.6-inch in diameter.
Step 5
After ensuring that all wire connections are secure, install the PEM in the bay.
Step 6
Tighten the power supply captive installation screws (
Figure 5-116
).

Caution
In a system with dual power supplies, connect each power supply to a separate input line. In case of a
line failure, the second source will most likely still be available.
Step 7
Remove the tape from the circuit breaker switch handle, and restore power by moving the circuit breaker
switch handle to the On (|) position.
Step 8
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
