If a DPC is not functioning normally, follow these guidelines to troubleshoot the DPC:
■ Make sure the DPC is properly seated in the midplane. Check that each ejector
handle has been turned clockwise and is tight.
Troubleshooting the Power System
To verify that a power supply is functioning normally, perform the following steps:
■ Check the LEDs on each power supply faceplate.
■ If an AC power supply is correctly installed and functioning normally, the
AC OK and DC OK LEDs light steadily, and the PS FAIL LED is not lit. For more
information about the LEDs, see “AC Power Supply LEDs” on page 22.
■ If a DC power supply is correctly installed and functioning normally, the
PWR OK, BRKR ON, and INPUT OK LEDs light green steadily. For more
information about the LEDs, see “DC Power Supply LEDs” on page 24.
