How to Remove and Replace a SPARC T3-2 Memory Risers and DIMMS

Fix

CAP PROBLEM OVERVIEW: SPARC T3-2 Server, Memory Risers and
DIMMs replacing.

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

Solaris Basic knowledge.

Time Estimate: 60 minutes

Task Complexity: 0

FIELD ENGINEER INSTRUCTIONS

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

Locate a Failed DIMM (LEDs)

Each memory riser has a Remind button, a Power LED, and Fault LEDs adjacent to each DIMM. This procedure describes how to identify a faulty DIMM using these buttons and LEDs.

1. Press the System Remind button to identify the memory riser that contains the faulty DIMM.
2. Lift and remove the faulty memory riser.
3. Press the Remind button on the memory riser to identify the faulty DIMM. An amber Fault LED will light next to the faulty DIMM.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Remove a Memory Riser Filler Panel
Caution - 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.

1. Prepare for servicing:
a. Attach an antistatic wrist strap.
b. Power off the server and unplug power cords from the power supplies.
c. Extend the server to the maintenance position.
d. Remove the top cover.
2. Locate the memory riser filler panel you want to remove.
3. Lift the filler panel straight up to remove it from the memory module socket.

Remove a DIMM Filler Panel

This procedure can be performed by customers. The system must be completely powered down before performing this procedure.

1. Prepare for servicing:
a. Attach an antistatic wrist strap.
b. Power off the server and unplug power cords from the power supplies.
c. Extend the server to the maintenance position.
d. Remove the top cover.
2. Locate the memory riser containing the DIMM filler panel you want to remove.
3. Lift the memory riser straight up to remove it from the memory module socket.
4. Locate the DIMM filler panel you want to remove.
5. Remove the DIMM filler panel by completing the following tasks.
a. Rotate both DIMM slot ejectors outward as far as they will go.The filler panel is partially ejected from the socket.
b. Carefully lift the DIMM filler panel straight up to remove it from the socket.

Remove a Memory Riser and DIMM
Caution - These procedures require that you handle components that are sensitive to static discharge. This sensitivity can cause the component to fail.

1. Prepare for servicing:
a. Attach an antistatic wrist strap.
b. Power off the server and unplug power cords from the power supplies.
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 as shown in the following figure.
a. If the memory riser Service Action Required LED is off, all DIMMs on this riser are operating properly.
b. 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 Remind button on the memory riser.
5. On DIMMs that display an amber Fault LED, remove the DIMMs.
a. Press down both DIMM slot ejector tabs as far as they will go.
b. Carefully lift the DIMM straight up.
Caution - Whenever you remove a memory riser or DIMM, you should replace it with another memory riser or a DIMM or a filler panel; otherwise, the server might overheat due to improper airflow.

Install a DIMM and a Memory Riser
1. Attach an antistatic wrist wrap and unpack the DIMMs and place them on an antistatic mat.
2. Install the DIMMs into the memory riser by performing the following tasks.
a. Ensure that the ejector levers at both ends of the memory module slot are in a fully open position.
b. Align each DIMM with the empty connector slot, aligning the notch in the DIMM with the key in the connector.
The notch ensures that the DIMM is oriented correctly.
c. Gently press the DIMM into the slot until the ejector tabs lock the DIMM in place.
Repeat these steps until each DIMM has been installed.
3. Push the memory riser module into the associated CPU memory riser slot until the riser module locks in place.
4. Return the server to operation:
a. Install the top cover.
b. Return the server to the normal rack position.
c. Reinstall the power cords to the power supplies and power on the server.

Install a Memory Riser Filler Panel
1. Align the memory riser filler panel with the empty slot.
2. Gently press the memory riser filler panel into the slot.
3. Return the server to operation:
a. Install the top cover.
b. Return the server to the normal rack position.
c. Reinstall the power cords to the power supplies and power on the server.

Install a DIMM Filler Panel

1. Locate the vacant DIMM slot on the memory riser.
2. Ensure that the ejector levers at both ends of the memory module slot are in a fully open position.
3. Install the DIMM filler panel by completing the following tasks.
a. Align the DIMM filler panel with the empty slot.
b. Gently press the DIMM filler panel into the slot until the ejector tabs lock the filler panel in place.
4. Return the server to operation:
a. Install the top cover.
b. Return the server to the normal rack position.
c. Reinstall the power cords to the power supplies and power on the server.

OBTAIN CUSTOMER ACCEPTANCE

1. Verify that the Service Required LED on the replaced part is not lit.
2. Verify that the Top Fan LED and the Service Required LED on the front of the server are not lit.
3. Run the ILOM ->show faulty command to verify that the fault has been cleared.



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

Boot system and monitor boot sequence for errors. Test functionality of system:
1. Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command (if only ALOM is supported run "showfaults -v" command) to verify that the fault has been cleared.
2. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear component faults.
   * If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required
3. Restart software applications per applicable administration guides to resume system operation.
