TASK COMPLEXITY: 1

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: V125/V210/V240 heatsink replacement

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

System needs to be shutdown by customer

Note (Thermal Interface Material) : Before start to remove heatsink , you must determine which type of TIM is separating CPU and heatsink FRU

* TIM1 is used on 1.0 GHz and 1.28 GHz servers. Glue backed foil material and is likely to have glued itself to CPU.

You should remove heatsink within ten minutes of having shut down server while the CPU is still warm and glue is workable.

* TIM2 is used on 1.34 GHz and 1.5 GHz servers. TIM2 is a gray paste. You should wait at least ten minutes after you shut down the server before you remove the heatsink FRU. TIM2 is a solid at room temperature, and the bond can be easily broken. Above 100 degrees Farenheit, TIM2 becomes a sticky paste and is hard to remove.

How to determine the TIM (CPU Speed) on the V210/V240 Server:

Issue the showfru command from Alom - eg:

sc> showfru

FRU_PROM at MB.SEEPROM

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

*** Follow standard ESD procedures to avoid Electrostatic Discharge

1. Power off server

2. Disconnect all power cables

3. Disconnect any data cables connected to any PCIe/XAUI card if needed

4. Remove the Top Cover

5. Remove any components that would interfere with the removal of heatsink. Depending on board, it will have one or two heatsinks

6. Detach fan power cable connectors from board (Connectors for CPU0 heatsink fans are labeled P0 F0 and P0 F1 on board, and connectors for the CPU1 are labeled P1 F0 and P1 F1)

7. Press down on fasteners securing heatsink and lift up

8. Remove heatsink

- Twisting heatsink 1 degree in a clockwise then 1 degree in counter direction until heatsink is loose

- Lifting heatsink off CPU

9. Use a clean cloth with cleaning solvent to clean any residue of top of the CPU (TIM2 might irritate your skin. Read SDS

10. To install heatsink do the reverse steps (Caution: Carefully remove protective liner on TIM on bottom of new heatsink)

OBTAIN CUSTOMER ACCEPTANCE
