FIELD ENGINEER INSTRUCTIONS

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

* The server must be fully shut down and the power cords disconnected.
* Do not operate the system with empty slots. Always insert a filler panel into an empty slot to reduce the possibility of system shut down.
* Take ESD Precautions.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Power off the server and remove the server module from the chassis

2. Remove the main cover

3. Identify which CPU and heatsink you are replacing.

* LED is off: CPU is OK.
* LED is lit (amber): CPU has encountered a voltage or heat error condition.

4. Remove the CPU and heatsink from the motherboard:

a. Hold down on the top of the heatsink to prevent it from tipping unevenly.

b. Twist the heatsink slightly to lift it off the board.

5. Pull the CPU socket lever slightly away from the socket.

a. Pivot the lever up, into the fully open position.

b. Open the hinged plate that covers the CPU until it is in the fully open position.

c. Lift the CPU out of the socket, leaving the lever and plate in the open position.

6. Install the new CPU, or reinstall the existing CPU.

a. Ensure that the CPU socket release lever and retainer plate are in the fully open position.

b. Align the CPU in the socket.

C. Gently set the CPU onto the pins in the socket.

d. When the CPU is fully seated in the socket, pivot the hinged retainer plate down onto the top of the CPU.

e. Pivot the release lever down and into the locked position, at the side of the socket.

7. Install the heat sink:

a. Using one syringe of thermal grease (0.2 ml/0.5 g), carefully apply grease to the top of the CPU in three lines

b. If you are reinstalling an existing heatsink, use an alcohol pad to clean all the old thermal grease from the component surface. Also, clean the dust
from the heatsink fins.

c. Turn the heatsink upright and reinsert the four springs and mounting screws.

d. Carefully position and align the heatsink over the CPU.

e. Lower the heatsink onto the CPU, aligning the mounting screws with their holes on the motherboard.

f. Using an adjustable torque driver, alternately tighten the two heatsink mounting screws, 180 degrees at a time, until each spring is completely
compressed.
