To install an AC PEM:
Step 1 Remove the AC PEM from the packaging and place on an anti-static surface.
Step 2 Verify that the circuit breaker on the PEM is in the OFF ( O ) position.
Step 3 Align the module with the guides in the rear power slot (1 or 2) that corresponds to the
slot in which the AC PSM populates. For example, if the AC PSM is installed in front
power slot 1, then install the AC PEM in rear power slot 1.
Slide the unit into the slot and firmly press the unit all the way into the slot. Tighten the
captive screws.
Step 4 (Optional) Install the redundant power module into the other rear power slot.
Step 5 Verify that the correlating AC PEM is properly installed in the appropriate slot.
