The following table describes the power indicator codes:
Power indicator codes | Condition |
---|---|
Green | Indicates that a valid power source is connected to the PSU and the PSU is operational. |
Blinking amber | Indicates an issue with the PSU. |
Not powered on | Indicates that the power is not connected to the PSU. |
Blinking green | Indicates that the firmware of the PSU is being updated.
CAUTION:Do not disconnect the power cord or unplug the PSU when updating firmware. If firmware update is interrupted, the PSUs will not function.
|
Blinking green and powers off | When hot-plugging a PSU, it blinks green five times at a rate of 4 Hz and powers off. This indicates a PSU mismatch due to efficiency, feature set, health status, or supported voltage.
If two PSUs are installed, you must ensure that:
CAUTION:Do not mix PSUs from previous generations of PowerEdge servers, even if the PSUs have the same power rating. This results in a PSU mismatch condition or failure to power on the system.
CAUTION:When correcting a PSU mismatch, replace the PSU with the blinking indicator. Do not swap the PSU to make a matched pair. This can result in an erroneous condition and an unexpected system shutdown.
CAUTION:To change from a high output configuration to a low output configuration or vice versa, you must power off the system.
CAUTION:AC PSUs support both 240 V and 120 V input voltages with the exception of Titanium PSUs, which support only 240 V. When two identical PSUs receive different input voltages, they can output different wattages, and trigger a mismatch.
