A PSU with an amber LED may have a fault. But an amber LED also indicates:
The external power is switched off with the DC power connected
The power supply is not properly seated in its slot
The array is powered off
A power supply internal fault has occurred
Verify that the power cord is plugged in, then check for and correct these conditions before you assume that the PSU in your
HPE storage array needs to be replaced.
CAUTION:
Before you attempt to replace a power supply:
Do not remove the PSU until you are ready to install the
replacement
Never unplug or unseat both PSUs at the same time
Use only UL-approved power cords
