Power Interface Board Introduction This section describes procedures to troubleshoot the controller enclosure power interface board. For troubleshooting procedures, refer to the "Master Troubleshooting Table" on page 275 Servicing Notes CAUTION The controller enclosure's power supply assembly must be serviced by a trained service technician ONLY. The power supply assembly has a modular design. It is a single, removable unit, that consists of the Power Interface Board and attached sheet metal frame. If you need to replace the Power Interface Board, you must replace the entire power supply assembly, not just the board. If there is an intermittent or complete power loss to the controller module, Battery Backup Unit, or controller enclosure fan module, it might be caused by either a defective power harness or Power Interface Board. The procedure in this section explains how to replace the power supply assembly, which includes the Power Interface Board. It assumes that you have already checked the power cords, checked for a failed power supply (see "Power Supply Module" on page 267), and replaced the power harnesses. 274 Controller Enclosure Troubleshooting
