How to Replace a Memory Riser and/or Memory DIMM in an Oracle Exalytics X2-4 or X3-4 system

Solution

CAP PROBLEM OVERVIEW: Memory Riser and DIMM replacement

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Oracle Exalytics Server Training.

TIME ESTIMATE: 45 minutes

TASK COMPLEXITY: 2-FRU

FIELD ENGINEER INSTRUCTIONS

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

If the system is still up and functioning, the customer should perform an orderly and graceful shutdown of applications and OS.

A data backup is not a prerequisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.

1. Power off the server and disconnect the power cords from the power supplies.
2. Extend the server to the maintenance position in the rack.
3. Attach an anti-static wrist strap.
4. Remove the top cover.

2. Identify the location of the faulty Memory Riser.

1. Each processor controls two of the system's memory risers. From right to left (when viewing the server from the front) the memory risers are P0/MR0, P0/MR1, P1/MR0, P1/MR1, P2/MR0, P2/MR1, P3/MR0, P3/MR1.
2. Press 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. Remove the Memory Riser and identify the faulty DIMM

1. Lift the Memory Riser straight up to remove it from the memory module socket.
2. set the Memory Riser aside on an antistatic mat.
3. 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.

4.Remove the faulty DIMM from the riser

1. After identifying the DIMM to be removed rotate both DIMM slot ejectors outward as far as they will go. This will partially eject the DIMM from it's socket.
2. Carefully lift the DIMM straight up to remove it from the socket.
3. set the DIMM aside on an antistatic mat.

5. Install the replacement DIMM and re-install the Memory Riser.

1. Unpack the replacement DIMM and confirm that it is the proper part to replace the one that was removed.
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. Align the memory riser with it's riser slot on the motherboard.
6. Push the memory riser module into it's associated CPU memory riser slot until the riser module locks in place.
   

6. Return the Server to operation

1. Replace the top cover
2. Remove any anti-static measures that were used.
3. Return the server to it's normal operating position within the rack.
4. Re-install the AC power cords and any data cables that were removed.
5. Power on server. Verify that the Power/OK indicator led lights steady on.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Boot up system and verify full functionality
