PS9648 Power Supply User Guide Introduction This chapter provides information needed to identify and fix problems with the PS9648 power supply module. Problems can be observed on the CommPlete system’s front panel LEDs, the control PC’s screen, or via audio alarm or alarm report. In addition, problems can be found when performing the Diagnostic Tests documented elsewhere in the CommPlete Communications Server User Guide.
4 Solving Problems Procedure 1. Turn off the power supply that is not being adjusted. 2. Place your voltmeter’s probes on the test points. 3. Two trimpots, one for each power supply, are located on the back of the chassis between the power supply fans. Adjust the 5 volt trimpot that is closest to the power supply that you are testing to 5.1 VDC by turning it clockwise to increase the voltage, or counterclockwise to decrease the voltage. 4. Check the measurement. 5.
PS9648 Power Supply User Guide Insertion and Removal of a Power Supply Qualified service personnel may insert or remove a power supply without turning off the system. We recommend that you insert the power supply slowly. If the power supply is not replaced, a cover plate must be installed. Safety Disconnect Device The switches on the power supplies are not safety disconnect devices. To reduce the risk of electric shock, unplug the two input power cords from the back of the CC9648.
