Solution 1349112.1 : How to Replace a Sun Fire X2100 M2 CPU & Heatsink

Applies to:

Sun Fire X2100 M2 Server - Version Not Applicable and later
Information in this document applies to any platform.

Goal

How to Replace a Sun Fire X2100 M2 CPU & Heatsink.

Solution

DISPATCH INSTRUCTIONS
- WHAT SKILLS DOES THE ENGINEER NEED: Replacement of a CPU and heatsink should only be done by trained service personnel.
- TIME ESTIMATE: 150 minutes
- TASK COMPLEXITY: 3

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.

Then power down the system and disconnect the Power Cord.

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW: How to Remove and Replace a X2100 M2 CPU and Heatsink
- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?:
- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Powering Off the server and Removing the Cover.

I. If the operating system (OS) is running, perform a shutdown of the OS, and then press and release the platform power button on the front panel.
II. Turn off all peripheral devices connected to the system.
III. Disconnect the AC power on the back panel of the server.
IV. Label and disconnect all peripheral cables and all telecommunication lines connected to I/O connectors or ports on the back panel of the system.
V. Before handling components, attach a wrist strap to a chassis ground (any unpainted metal surface).
VI. Loosen the two captive screws securing the cover to the chassis
VII. Pull the cover slightly toward the back of the server and then straight up to remove it.
VIII. Lift the cover and remove it.

Removing a CPU and Heatsink

I. Remove Air Duct: Remove the screw fastening the air duct to the chassis divider.
II. Unfasten the four screws securing the heatsink to the board
Caution - The heatsink can become extremely hot. Be sure it has had sufficient time to cool before handling.
III. Twist the heatsink slightly to the right or left to break the seal with the thermal grease.
IV. Lift the heatsink away from the CPU.
V. Place the heatsink upside-down on a flat surface to prevent the thermal grease from contaminating other components.
VI. Pull the socket release lever up to the fully open, perpendicular position.
VII. Open the CPU cover.
VIII. Lift the CPU out of the socket, leaving the release lever in the open position.
Note - Ensure that no thermal grease that might be left from the heatsink comes into contact with the CPU socket or underside of the CPU chip.

Installing a CPU and Heatsink

Caution - Take the appropriate ESD precautions
I. Unpack the new CPU.
II. Ensure that the socket release lever is in the fully open, perpendicular position and the CPU cover is open
III. Align the small triangle, on the upper left corner of the CPU, with the triangle on the corner of the socket.
IV. Insert the CPU into the socket
Caution - If the CPU is correctly aligned, you should be able to easily insert the CPU into the socket. If you feel more than minimal resistance, stop and recheck the alignment. Forcing a misaligned CPU into the socket can permanently damage the device.
V. When the CPU is fully seated in the socket, close the CPU cover. The CPU cover might not align correctly with the chip, after it is installed. If this happens open the cover, and push it slightly to the side to better align it with the chip, and reclose the cover
VI. Rotate the socket release lever down until it snaps into place, securing the CPU in the socket.
VII. Use the syringe to apply approximately 0.1 ML/CC of thermal grease in a circular pattern to the top of the CPU.
VIII. Gently distribute the thermal grease and remove any excess so that only an extremely thin, uniform layer remains. If any voids or crevices appear that could lead to air pockets, reapply the grease until you achieve a thin but compact consistency.
IX. Use an alcohol pad to remove all thermal grease from the bottom of the heatsink.
X. Inspect the heatsink for dust and lint. Clean if necessary.
XI. Carefully position the heatsink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.
Caution - If the heatsink is moved too much during its installation, the layer of thermal grease may become uneven, leading to component damage.
XII. Fasten the four screws attaching the heatsink to the motherboard.
XIII. Replace the air duct
XIV. Reinstall the cover.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
AN OPERATIONAL STATE: Verify the proper device operation
