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. |
