Figure 6. DC PSU status indicator
1. DC PSU status indicator
Table 8. DC PSU status indicators
Convention Power indicator pattern Condition
A Green A valid power source is connected to the PSU and that the PSU is operational.
B Flashing green When hot-adding a PSU, the PSU indicator flashes green. This indicates that there is a
PSU mismatch with respect to efficiency, feature set, health status, and supported
voltage. Ensure that both the PSUs are of the same capacity.
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 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 turn off the system.
CAUTION: AC PSU support both 220 V and 110 V input voltages with the
exception of Titanium PSU, which support only 220 V. When two identical
PSU receive different input voltages, they can output different wattages,
and trigger a mismatch.
CAUTION: If two PSU are used, they must be of the same type and have the
same maximum output power.
CAUTION: Combining AC and DC PSU is not supported and triggers a
mismatch.
D Not lit Power is not connected.
