motherboard. This LED lights to indicate that the fault remind circuitry is working properly
in cases where no components have failed and, as a result, none of the component fault
LEDs illuminate. For more information on the fault remind status indicator and the location

PWRGD and is located on the rear of the server near PCIe slot 2. This LED lights to inform
the service technician that the motherboard is receiving standby power from at least one
of the power supplies. This LED is provided to help prevent service actions on the server
internal components while the AC power cords are installed and power is being supplied to
the server.
If a PCIe card is installed in PCIe slot 2, this LED might not be visible.
Note -
The service instructions for all server internal components require that all AC power

be removed from the power supplies prior to removing the server top cover.

Troubleshooting System Cooling Issues

Maintaining the proper internal operating temperature of the server is crucial to the health of the
server. To prevent server shutdown and damage to components, address over temperature- and
hardware-related issues as soon as they occur. If your server has a temperature-related fault, the
cause of the problem might be:
"External Ambient Temperature Too High" on page 33
■
"Airflow Blockage" on page 34
■
"Cooling Areas Compromised" on page 34

"Hardware Component Failure" on page 34
■
External Ambient Temperature Too High
Server component cooling relies on the movement of cool air through the server. The cool air is
pulled into the server from its external environment. If the ambient temperature of the server's
external environment is too high, cooling does not occur, and the internal temperature of the
server and its components increases. This can cause poor server performance or a failure of one
or more components.
Action: Check the ambient temperature of the server space against the environmental
specifications for the server. If the temperature is not within the required operating range,
remedy the situation immediately.
