Replacing a DC Power Entry Module
Replacing a DC Power Entry Module
A DC power entry module (PEM) contains few active components, so it rarely needs replacement. To
replace a PEM, refer to Figure 5-1 and proceed as follows:
Step 1 Remove the cable guard: Loosen the captive screw at its base and, holding the cable guard at its top and
bottom, swing the guard away from the system at the base.
Step 2 Switch the circuit breaker on the PEM to the OFF position.
Step 3 Grasp the pluggable terminal block and disconnect it from the module.
Step 4 Remove the wiring from the strain relief mechanism.
Step 5 Loosen the captive screws that secure the PEM in the PE-BC.
Step 6 Pull the power entry module out of the power entry back card (PE-BC).
Step 7 Slide in the replacement module until it seats in the D-connector on the PE-BC.
Step 8 Tighten the screws to secure the PEM in the PE-BC.
Step 9 Place the wiring within the strain relief mechanism.
Step 10 Plug in the terminal wiring block into the DC receptacle.
Step 11 Switch the circuit breaker on the PEM to the ON position.
Step 12 Re-attach the cable guard after confirming correct system operation.
