FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Server X3-2 (Sun Fire X4170 M3) Fan Module needs replacement

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

The server's fan modules support replacement while the server is running. However to maintain adequate airflow to properly cool the server the top cover fan assembly door can only be left open for 60 seconds.Leaving the door open for more than 60 seconds, while the server is running, might cause the server to overheat and shut down. Also note that if a fan module is not reinserted within approximately 30 seconds the system will detect a fan column fault and power off the server. Due to this restriction when performing a hot-swap fan replacement make sure the new fan module is ready for insertion before removing the failed unit so that the fan location is not left empty beyond this time limit.

Animation videos are available to demonstrate the fan module replacement process for these servers. please refer to the following links:

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.

1. Extend the server to the maintenance position in the rack.
2. To access the fan modules, open the server fan door.

2. Confirm the fan module failure and it's location.

1. Confirm which fan module is to be replaced. Each fan module has a status indicator (LED). If the LED is lit amber, the fan has failed. The status LEDs are located on the chassis mid-wall adjacent to and aligned with the fan module.
2. If the service is to be performed while the system is up and running make sure that the fan assembly door is not left open for more than 60 seconds.

3. Remove the fan module

1. Using your thumb and forefinger, grasp the fan module in the finger recesses located in the plastic between the fans.
2. Lift the fan module straight up and out of the chassis and set it aside on an antistatic mat. (Caution- When removing a fan module, do not rock it back and forth. Rocking the fan module can cause damage to the motherboard connectors)

4. Install the replacement fan module

1. Remove the replacement fan module from its packaging and place it on an antistatic mat.
2. With the top cover fan assembly door open, install the replacement fan module into the server. (The fan modules are keyed to ensure that they are installed in the correct orientation)
3. Press down on the fan module and apply firm pressure to fully seat the fan module.
4. Verify that the Fan status LED that aligns with the replaced fan module is lit green.
5. Close the top cover fan assembly door.
6. Verify that the Top Fan LED on the front of the server and the Service Required LEDs on the front and rear of the server are extinguished.

5. Check system status LEDs

1. Due to a known bug sometimes after a hot-swap fan replacement the HOST POWER OK LED may be left in a blinking green state instead of the proper solid green state. After performing a fan replacement this should be checked for.
2. If the HOST POWER OK LED is left in a blinking state instead of returning to a solid state the SP should be reset.
3. To reset the SP using the Webgui login to the ILOM Web page and expand the ILOM Administration section in the left column and then select Maintenance. In the main window select the Reset SP tab and click the Reset SP button.
4. To reset the SP from the ILOM cli ssh to the ILOM and execute "reset /SP" answer 'y' when prompted if you are sure you want to reset the SP.
5. After the SP is reset the HOST POWER OK LED should return to it's proper solid state.

6. Return the Server to operation

1. Return the server to it's normal operating position within the rack.
2. Check all power and data cables to ensure that no connections were disturbed during the service.
3. Verify that the Power/OK indicator led lights steady on and that system is operating properly.
