LED Description Action
Temperature The system temperature has
exceeded a threshold level.
A failing fan can cause the
Temperature LED to be lit. 1. Make sure that the heat sink is seated correctly.
2. Determine whether a fan has failed. If it has failed,
replace the failing fan.
3. Make sure that the room temperature is not too high.
See “Server features and specifications” on page 3
for the server temperature information.
4. Make sure that the air vents are not blocked.
5. Make sure that the fan on the adapter and the
network adapter is seated correctly. If it has failed,
replace the failing component.
6. If the failure remains, go to

When only the Microprocessor
LED is lit, a microprocessor
has failed. If the Configuration LED is not lit, a microprocessor failure
occurs, complete the following steps:
1. (Trained technician only) Make sure that the failing
microprocessor and its heat sink, which are indicated
by a lit LED on the system board, are installed
correctly. See “Installing a microprocessor and heat
sink” on page 276 for information about installation
and requirements.
2. (Trained technician only) Replace the failing
microprocessor (see “Installing a microprocessor and
heat sink” on page 276).
3. If the failure remains, go to
http://www.lenovo.com/support.
Microprocessor
Micropro
Configuration
When both the Microprocessor
and Configuration LEDs
are lit, the microprocessor
configuration is invalid.
If the Configuration LED and the Microprocessor LED
are lit, the system issues an invalid microprocessor
configuration error. Complete the following steps to
correct the problem:
1. Check the microprocessors that were just installed
to make sure that they are compatible with each
other (see “Installing a microprocessor and heat
sink” on page 276 for additional information
about microprocessor requirements) and use the
Setup utility and select System Information
→
System Summary
→
Processor Details to verify the
microprocessors information.
2. (Trained technician only) Replace the incompatible
microprocessor.
3. Check the system-error logs for information about
the error. Replace any component that is identified
in the error log.
