Chapter 29 Replacing Parts
Replacing a DC Power Entry Module
Replacing a DC Power Entry Module
DC Power Entry Modules (PEMs) contain few active components so they should rarely need
replacement. Access is from the back of the node.
To remove a PEM, use the following procedure:
Step 1
Check the node system voltage by using the Display Power (
dsppwr)
command. Note which input has
failed, A or B. Power Supply A is the unit on the right side facing the rear of the node.
Step 2
Turn off the primary source of power to the PEM to be replaced.
Step 3
Turn off the circuit breaker on the PEM to be replaced.
Step 4
Remove the two screws holding the conduit box cover (see Figure 29-3). Or, remove the plastic cover
plate over the input terminal block.
Step 5
Remove the power input wiring at the PEM terminal block.
