The PSU indicators provide the following information:
Table 5. PSU indicators
Convent Power indicator
ion pattern
A Green
B Flashing amber
C Not lit
Condition
In standby mode, the handle lights green indicating that a valid power
source is connected to the PSU and that the PSU is operational.
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: AC power supplies support both 220 V and 110 V input
voltages. When two identical power supplies receive different
input voltages, they can output different wattages, and trigger a
mismatch.
CAUTION: All power supplies used must be of the same type and
have the same maximum output power.
Power is not connected.
