See Section 1.2, “Sun Fire X4140 Server Chassis Overview” on page 1-3 for more
information about system status LEDs.
3.3.3 Detecting Fan Module Failure
The following LEDs are lit when a fan module fault is detected:
■
Front and rear Service Required LEDs
■
Top Fan LED on the front of the server
■
Fan Fault LED on or adjacent to the faulty fan module
If an overtemperature condition occurs, the front panel processor overtemperature
LED becomes lit and a message is displayed on the console and logged by the ILOM.
The system Overtemp LED might be lit if a fan fault causes an increase in system
operating temperature. See
Section 1.3, “Sun Fire X4140 Server Front Panel Features”
on page 1-8 for more information about identifying and interpreting system LEDs.
3.3.4 Removing a Fan Module
Caution – Hazardous moving parts. Unless the power to the server is completely
shut down, the only service permitted in the fan compartment is the replacement of
the fan modules by trained personnel.
1. Extend the server into the maintenance position.
See Section 2.5, “Extending the Server to the Maintenance Position” on page 2-5 .
2. Unlatch the fan module door.
Pull the release tabs back to release the door. Open the top cover toward the rear
of the server.
Note – Close the top cover door immediately after replacing the fan to maintain
airflow in the server. Leaving the door open for more than 60 seconds while the
server is running might cause the server to overheat and shut down.
3. Identify the faulty fan module with a corresponding Service Required LED.
The Fan Fault LEDs are located on the fan board.
4. Using thumb and forefinger in between the two fans, pull the fan module up
and out of the connector.
