FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4270 M2 CPU & Heatsink needs replacement

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

Customer should perform an orderly and graceful shutdown of applications and OS
A data backup is not a pre-requisite but is a wise precaution

Note:

If this server is part of an Exadata, please follow shutdown instructions in DOC ID: 1188080.1

If this server is part of a Big Data Appliance, please follow shutdown instruction in DOC ID: 2099858.1

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare server for service

- Turn on Server Locate LED from OS, ILOM or button to identify server requiring service
- Power off server and disconnect AC power cord(s) from power supply(ies)
- Remove server from rack
- Attach antistatic wrist strap
- Remove top cover. Ensure AC power cord(s) are removed before opening top cover.

Remove CPU
1. Identify location of faulty CPU. Press Fault Remind button on motherboard. CPU fault LEDs are located next to CPUs
- CPU LED off: OK. LED is on (amber): must be replaced(CPU0 is closest to power supply bay)
2. Using Hex wrench, unscrew two screws in heatsink for faulty CPU (alternately half turns until fully removed)
3. Twist heatsink to break grease seal, lift off heatsink and place it upside down on flat surface
4. Use alcohol pad to clean thermal grease off CPU and heatsink
Do not to get your fingers greased so you don't contaminate other parts
5. Check heatsink for dust and lint. Clean if needed
6. Disengage CPU release lever pushing down and moving it to side away from CPU, then rotating lever upward
7. Open pressure frame and carefully lift out the CPU. Place the CPU on an ESD protected mat or bag.

Caution - If a CPU is being removed and not replaced, a socket cover must be installed to protect the socket pins from damage.

Install new CPU
1. Using antistatic wrist, unpack CPU and place it on antistatic mat
2. Orient CPU with socket alignment tabs and place CPU in socket (Ensure orientation is correct)
3. Lower pressure frame: Make sure pressure frame sits flat around periphery of CPU
4. Engage release lever rotating it downward and slipping it under catch
5. Use syringe (supplied with new CPU) to apply approx. 0.1 ml of thermal grease to center-top of CPU. Do not distribute grease.
Caution - Failure to apply new thermal grease may cause the CPU to overheat
Note - If the heatsink has some how become broken, then a replacement heatsink should be pre-greased and no additional grease should be added to the CPU.
6. Orient heatsink so two screws line up with mounting studs and so that heatsink is aligned with other heatsink, so front of heatsink should align with front of the other one
7. Position heatsink on CPU, aligning it with mounting posts to reduce movement after it makes initial contact with thermal grease layer
Caution - If heatsink assembly is moved a lot on installation, thermal grease layer may not be well distributed.
8. Tighten screws alternately one-half turn until seated
9. Reinstall top cover.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO
RETURN THE SYSTEM TO AN OPERATIONAL STATE:

1. Reconnect power cord(s) to power supply and power on server. Verify AC Present LED is lit
2. Return server to normal rack position.
3. Wait 2 minutes for ILOM to boot.
4. Connect to ILOM via serial management or network management port and clear CPU fault:
a. Verify path to CPU is faulted, this should provide the fault information
-> show faulty
b. Clear the fault, use the path identified in (a) for P0 or P1
-> set /SYS/MB/P0 clear_fault_action=true
    c. Verify fault is cleared, this should return nothing
        -> show faulty
5. Power on the server, either from ILOM command or pressing the power button.
6. Monitor the server console to ensure it passes BIOS POST and does not fault again, and continue monitoring to verify the server OS starts and boots normally.

Note:

If this server is part of an Exadata, please follow restart instructions in step 7 of DOC ID: 1188080.1

If this server is part of a Big Data Appliance, please follow restart instructions in DOC ID: 2099858.1
