NOTE
If the LEDs (the DC-OK LED for EPU-AM, and the AC-OK and DC-OK LEDs for
EPU-BM) do not turn green, there might not be any power being supplied to the
power supply module. Make sure that the power switch of the power supply module
is set to ON and that the power supply module is installed correctly.
If the problem persists, see the
AX6700S/AX6600S/AX6300S/AX3800S/AX3600S/AX2400S Troubleshooting
Guide.
NOTE
If the LEDs (the DC-ALM LED for EPU-AM, and the DC-FAIL LED for EPU-BM) turn
red, a power supply module failure has occurred. If a failure has occurred, see the
AX6700S/AX6600S/AX6300S/AX3800S/AX3600S/AX2400S Troubleshooting
Guide and take corrective action.
