Controller power supplies have a
single bi-color LED indicator to convey information about the state of the supply.
Table 1 describes the
meaning of each indicator.
Table 1. Summary of LED indicators for the
PSUs
| Indicator |
Color |
Meaning |
| Power supply status |
Green |
- Off - There is no AC input to the
PSU, or the PSU is in a fault state that does not allow AC input.
- On - The power supply is receiving AC
line cord power and is operating normally.
- Slow flash - AC is present. However, check the Event Log for errors, such as a possible fan
failure.
- Flashing - The power supply firmware is being updated. No actions are required; do not remove AC
power.

| Amber |
A fault needs to be resolved.
- Slow flash - The power supply is on, but needs maintenance. Check the Event Log for errors and
events where the power supply continues to operate, such as high temperature, high power, high
current, or slow fan.
- On - AC power is lost or the cable is unplugged, but power is still being supplied from the
second power supply. There might also be a critical fault in the power supply that causes it to shut
down (such as a fan failure). Check that the AC power cable is plugged and power is provided. If the
amber LED persists, check the Event Log.
