FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS: 

PROBLEM OVERVIEW: An Oracle Server X5-2, X6-2 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, when removing a fan module please note that the system will shutdown the server if a fan module is not reinserted within the 20 second timeout.  In anticipation of this time limit, prior to starting the replacement procedure, obtain the replacement fan module and verify that the new fan module is ready for installation.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Refer to this document:

"How to Replace an Oracle Server X5-2, X6-2 Fan Module"
http://docs.oracle.com/cd/E41059_01/html/E48312/napsm.z40000091014050.html#scrolltoc

A. Get the new part ready.

1. Obtain box that new part came in.

2. Open box, unwrap the part from any packing material, and lay the new part on an anti-static pad near the server that you are servicing.

B. Prepare the server for service.

1. Extend the server to the maintenance position in the rack.

2. Attach an anti-static wrist strap.

3. To access the fan modules, open the server fan door.

C. 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.

   Caution - Close the server fan door within 60 seconds to maintain adequate airflow to properly cool 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.

D. Remove the faulty 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 please note that the system will shutdown the server if a fan module is not reinserted within the 20 second timeout.  In anticipation of this time limit, prior to starting the replacement procedure, obtain the replacement fan module and verify that the new fan module is ready for installation.  The fans are N+1 redundant so only one of the 16 fan motors can be failed at one time otherwise this will also shutdown the server.
   
   
   Caution - When removing a fan module, do not rock it back and forth. Rocking the fan module can cause damage to the motherboard connectors.

E. Install the replacement fan module.

1. Remove the replacement fan module from its packaging and place it on an antistatic mat. This should have been done before starting the replacement procedure so the fan is ready to install when the failed fan is removed.
   

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 is off.

5. Close the fan 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.

F. 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.
