DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:General Sun X86 servers hardware knowledge.
Some awareness about specific being of FB DIMMS, in comparison of common DDRx DIMMs
in the PC world for instance.

DELIVERY REQUIREMENT: during a maintenance window.

Estimate AP Duration = 1.25 hours
FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:
- Data backup not required but recommended as a precaution.
- Orderly shutdown of applications, then the OS and power down of server.
WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Remove a Memory Riser and DIMM

1. Prepare for servicing:
a. Attach an antistatic wrist strap.
b. Power off the server.
c. Extend the server to the maintenance position.
d. Remove the top cover.

2. Identify the memory riser with the faulty DIMM by pressing the Fault Remind button on the air divider.
- If the memory riser Service Action Required LED is off: all DIMMs on this riser are operating properly.
- If the memory riser Service Action Required LED is on (amber): one or more of the DIMMs installed on this riser is faulty or misconfigured.
3. Lift the memory riser that has its Service Action Required LED lit straight up to remove the memory riser from the memory module socket.

4. Identify the faulty or misconfigured DIMM(s) by pressing the Fault Remind button on the memory riser.
- If the DIMM Service Action Required LED is off: DIMM is operating properly.
- If the DIMM Service Action Required LED is on (amber): DIMM is faulty or misconfigured and corrective action is required.

5. To remove the DIMM do the following:
a. Rotate both DIMM slot ejectors outward as far as they will go. (The DIMM is partially ejected from the socket).
b. Carefully lift the DIMM straight up to remove it from the socket.

Install Memory Risers and DIMMs

1. Unpack the DIMMs and place them on an antistatic mat.
2. Ensure that the ejector levers at both ends of the memory module slot are in a fully open position.
3. Align the DIMM with the empty slot.

Align the notch in the DIMM with the key in the connector. The notch ensures that the DIMM is oriented correctly.

4. Gently press the DIMM into the slot until the ejector tabs lock the DIMM in place.

- If the DIMM does not easily seat into the connector, verify that the notch in the DIMM is aligned with the key in the connector.
- If the notch is not aligned, damage to the DIMM might occur.

5. Repeat Steps 2 through 4 until all replacement DIMMs are installed.

6. Push the memory riser module into the associated CPU memory riser slot until the riser module locks in place.

7. Return the server to operation:
a. Install the top cover.
b. Return the server to the normal rack position.
c. Power on the server.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
1. Fully monitor the BIOS startup to ensure all expected memory is present.
2. Bootup the OS.
3. Check total memory available and monitor error logs to check any new memory error messages.

PARTS NOTE:
Whenever you remove a memory riser filler panel, replace it with another filler panel or a memory riser; otherwise, the server might overheat due to improper airflow.
