If using a DC power supply, each NPT-1020/EXT-2U platform has two power modules.

To replace the power module:
1. Cut off the power source connected to the power module by turning off the corresponding power
switch on the RAP.
2. Disconnect the power cable from the replaced power module on the panel.
3. Open the two screws fastening the power module to the platform.
4. Hold the handle on the panel and pull the module to be replaced outward until it is released from the
backplane.
