WHAT SKILLS ARE REQUIRED?: No special skills required, Customer Replaceable Unit (CRU) procedure

TIME ESTIMATE: 160 minutes

Task Complexity: 0

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW: replace a faulty DIMM

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

ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat

DAMAGE ALERT: Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc. If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the return part to avoid any damages during shipping.

The customer should conduct an orderly software system shutdown. Then power down system and disconnect the power cords. A data backup is not a pre-requisite but is a wise precaution.

WHAT ACTIONS ARE REQUIRED:

A) Remove a DIMM

A DIMM is a cold-service component that can be replaced by a customer.

Caution: Do not leave DIMM slots empty. You must install filler panels in all empty DIMM slots.

1. Take the necessary ESD precautions.

2. Remove the processor module with the faulty DIMM from the server and remove the cover from the processor module, if you have not already done so.

3. Locate the DIMMs that need to be replaced. Locate a Faulty DIMM Using the Blue DIMM Fault Remind Button located on the Motherboard.

4. Push down on the ejector tabs on each side of the DIMM until the DIMM is released.

Caution - DIMMs and heat sinks on the motherboard might be hot.

5. Grasp the top corners of the faulty DIMM and lift it out of its slot.

6. Place the DIMM on an antistatic mat.

7. Repeat Step 4 through Step 6 for any other DIMMs you intend to remove.

8. Determine if you will be installing replacement DIMMs at this time.

- If you will be installing replacement DIMMs at this time, go to the Install a DIMM section below.

- If you will not be installing replacement DIMMs at this time, follow these procedures to reinsert the processor module back into the server:
a. Install filler panels in the empty DIMM slots.

Caution - Do not leave DIMM slots empty. You must install filler panels in all empty DIMM slots.

b. Place the cover back onto the processor module and insert the processor module back into its slot in the server.

B) Install a DIMM

1. Take the necessary ESD precautions.

2. Remove the processor module from the server and remove the cover from the processor module, if you have not already done so.

3. Unpack the replacement DIMMs and place them on an antistatic mat.

4. Ensure that the ejector tabs on the connector that will receive the DIMM are in the open position.

5. Align the DIMM notch with the key in the connector.

Caution - Ensure that the orientation is correct. The DIMM might be damaged if the orientation is reversed.

6. Push the DIMM into the connector until the ejector tabs lock the DIMM in place.
If the DIMM does not easily seat into the connector, check the DIMMs orientation.

7. Repeat Step 4 through Step 6 until all new DIMMs are installed.

8. Place the cover back onto the processor module and insert the processor module back into its slot in the server.

9. 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.

10. The following link to the T5-4 Service Guide, can be used as a guideline for verifying Replacement DIMMs: http://docs.oracle.com/cd/E29659_01/html/E29663/z40000081390135.html#scrolltoc

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTIONS ARE REQUIRED 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 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.
