Convention Power indicator
pattern
Condition
A
Green
The handle/LED indicator lights green indicating that a valid power
source is connected to the PSU and that the PSU is operational.
B
Flashing green
When hot-adding a PSU, the handle of the new power supply unit
flashes green five times at 4 Hz rate and turns off. This indicates
that the new PSU is mismatched with the PSU that is installed (in
terms of efficiency, feature set, health status, and supported
voltage). Use a PSU that matches the capacity of the PSU that is
installed.
C
Flashing amber
Indicates a problem with the PSU.
CAUTION: When correcting a PSU mismatch, replace only
the PSU with the flashing indicator. Swapping the opposite
PSU to make a matched pair can result in an error condition
and unexpected system shutdown. To change from a High
Output configuration to a Low Output configuration or vice
versa, you must power down the system.
CAUTION: If two power supplies are used, they must be of
the same type and have the same maximum output power.
CAUTION: Combining AC and DC power supplies is not
supported and triggers a mismatch.
D
Not lit
Power is not connected.
