FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: CPU/Fan heatsink failure

OBTAIN CUSTOMER ACCEPTANCE

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

A data backup is not a pre-requisite but is a wise precaution.
The customer should conduct an orderly software system shutdown.

 WHAT ACTION DOES THE FIELD ENGINEER/CUSTOMER ADMINISTRATOR NEED TO TAKE:

Removing the CPU Fan and Heat Sink Assembly
1.Power off the system and open the chassis.

2.Locate the CPU fan and heat sink assembly.

■If you are replacing the CPU fan and heat sink assembly for CPU0, remove the rear fan.

■If you are replacing the CPU fan and heat sink assembly for CPU1, remove the hard drive assembly.

3.Position the chassis.

4.Disconnect the fan cable for the CPU fan and heat sink assembly that you are replacing from the motherboard.

5.Release the CPU fan and heatsink assembly clips.

Caution – Do not damage the motherboard components located around the CPU fan and heat sink assembly.

Note – Check the orientation of the clips before removal. You must reinstall the clips in the same orientation later.

See the Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual for more details about the clips reinstallation

6.Remove the CPU fan and heat sink assembly.

Caution – Do not place the CPU fan and heat sink assembly face down on any surface. The thermal pad might attract dirt and oil from the surface, which contamination prevents efficient heat transfer.

7.If necessary, repeat Step 4 through Step 6 of this procedure to remove the second CPU fan and heat sink assembly.

Caution – Do not power on the system if the CPU fan and heat sink assembly is not installed. Powering on the system will immediately damage the CPU.

Installing the CPU Fan and Heat Sink Assembly

1.Open and position the chassis.
Caution – If the CPU fan and heat sink assembly is not installed, the workstation should not be powered on.

2.Identify the CPU fan and heat sink assembly location on the motherboard.
The CPU fan and heat sink assembly is installed on CPU0 or CPU1.

3.Remove the CPU fan and heat sink assembly from its packaging.

4.Place the CPU fan and heat sink assembly onto the CPU.

5.Arrange the CPU fan so that the cable is facing the bottom-front corner of the chassis.

6.Fasten the CPU fan and heat sink assembly onto the CPU.

7.Connect the CPU fan and heat sink assembly cable.
Each CPU fan and heat sink assembly cable has a designated connector on the motherboard. Connect the fan cable connector for CPU0 to FAN1. Connect the fan cable connector for CPU1 to FAN3.

8.If necessary, repeat Step 2 through Step 7 of this procedure to install the second CPU fan and heat sink assembly.

9.Reposition the chassis.

10.Inspect the CPU fan and heat sink assembly clips, cabling

11. Install the access panel, power on the system, and verify the component installation

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN the SYSTEM TO AN OPERATIONAL STATE:

Restart software applications per applicable administration guides to resume system operation.
