4.Replace the power supply if the fuse continues to blow and a defective PCB or short cannot be found. See “Step 7D: Remove and Replace the Power Supply (if required)” on page 3-17.

Step 7C: Check the Power Factor Indicator and Reset Button

The front panel of APSU112 provides a Power Factor LED and Reset button. If the cabinet power factor is exceeded by overload of PCBs, the PF LED will turn on.

If the PF LED indicator turns on, press the PF reset button with a pointed tool or pencil. If the PF LED turns off and does not turn on again it may have been turned on by a current surge while installing a PCB while the power supply was turned-on.

When a PF alarm is indicated, check that the cabinet power factor is not exceeded using “Worksheet 7 – System Power Factor Check” on page 2-42. If the Power factor has been exceeded relocate any PCBs that are causing the PF to be exceeded.
