Figure 6 AC PSU status indicator (continued)
1. AC PSU status indicator/handle
This table describes the AC PSU status indicators and what condition is the PSU when
the power indicator light is green, flashing green, flashing amber, and when it is not lit.
Table 7 AC PSU status indicators
Convention Power indicator
pattern Condition
A Green A valid power source is connected to the PSU and the PSU is operational.
B Flashing green When the firmware of the PSU is being updated, the PSU handle flashes
green.
C Flashing green and turns
off When hot-adding a PSU, the PSU handle flashes green five times at 4 Hz
rate and turns off. This indicates a PSU mismatch with respect to
efficiency, feature set, health status, and supported voltage.
Note
Ensure that both the PSUs are of the same capacity.
CAUTION
For AC PSUs, use only PSUs with the Extended Power Performance
(EPP) label on the back.
D Flashing amber Indicates a problem with the PSU.
CAUTION
When correcting a PSU mismatch, replace only the PSU with the
flashing indicator. Swapping the PSU to make a matched pair can
result in an error condition and unexpected appliance shutdown. To
change from a high output configuration to a low output configuration
or vice versa, you must turn off the appliance.
CAUTION
AC PSUs support both 220 V and 110 V input voltages. When two
identical PSUs receive different input voltages, they can output
different wattages, and trigger a mismatch.
CAUTION
If two PSUs are used, they must be of the same type and have the
same maximum output power.
CAUTION
Combining AC and DC PSUs is not supported and triggers a mismatch.
E Not lit Power is not connected.
