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, blinking green, blinking amber, and when it is not lit.
Power indicator
codes Condition
Green A valid power source is connected to the PSU and the PSU is operational.
Blinking amber Indicates a problem with the PSU.
Not illuminated Power is not connected to the PSU.
Blinking green When the firmware of the PSU is being updated, the PSU handle blinks
green.
CAUTION Do not disconnect the power cord or unplug the PSU when
updating firmware. If firmware update is interrupted, the PSUs do not
function.
Blinking green and
turns off When hot-plugging a PSU, the PSU handle blinks green five times at a
rate of 4 Hz and turns off. This indicates a PSU mismatch with respect to
efficiency, feature set, health status, or supported voltage.
CAUTION If two PSUs are installed, both the PSUs must have the
same type of label; for example, Extended Power Performance (EPP)
label. Mixing PSUs from previous generations of PowerEdge servers
is not supported, even if the PSUs have the same power rating. This
results in a PSU mismatch condition or failure to turn the system on.
CAUTION When correcting a PSU mismatch, replace only the PSU
with the blinking 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 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.
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.
