Power Supply Indicator

Each HP Server tc4100 Power Supply has an indicator as shown in
own power cord connection. The HP Server tc4100 comes with one Power Supply (standard); a second Power
Supply for redundancy is optional.
NOTE The release latch, which is spring loaded, must be up to insert the power cord. The power
supply cannot be removed from the chassis with the power cord connected to the AC In
connector. The power cord must be removed before pushing down on the release latch to
free the power supply from the chassis.

Power Supply and Server Status
This indicates that the output voltages are present. It does not indicate the
status of the HP Server tc4100 software.
This indicates the Server is powered off, the AC line cord is unplugged, or the
power supply has failed, which may include a fan failure (turning too slowly).
If a fan fails in one of two supplies, the defective supply will continue to
operate until it reaches the thermal shutdown limit. The second power supply
(redundant power supply) will continue to operate providing the necessary
power. Refer to
