How to remove and replace an X4500 MEMORY DIMM

Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
This component is a CRU and can be replaced by anyone.

TIME ESTIMATE: 20 minutes

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?: 1) Always wear an antistatic strap when handling DIMMs. 2) Handle DIMMs by the edges only. 3) Place DIMMs in antistatic containers for storage. 4) Place DIMMs on an antistatic mat when working with them.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Power off the server

2. Remove the cable management arm as described in one of the following:

Sun Fire X4500/X4540 Installation Guide_
Sun X4500-J Slide Rail Installation Guide (X4500)
Early-Production Slide Rail and CMA Information (X4500)
3. Remove the system controller

4. Locate the DIMM slot on the CPU board on which you want to install or replace a DIMM.

The DIMM fault LEDs in the DIMM slot ejector levers indicate which DIMM has failed. These DIMM fault LEDs can be lit for up to one minute by a capacitor on the CPU board. To light the fault LED from the capacitor, push the small blue button on the CPU board, labeled “Press to see fault.”

One end of the DIMM ejector levers contain LEDs that can indicate a faulty DIMM:

DIMM fault LED is off: The DIMM is operating properly.
DIMM fault LED is on (amber): The DIMM is faulty and must be replaced.
5. To remove a DIMM:

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.

1. Install the DIMMs.

a. Ensure that the DIMM slot ejectors at each end of the memory socket are fully open (rotated outward) to accept the new DIMM.

b. Align the notch in the bottom edge of the DIMM with the key in the DIMM socket

c. Press down evenly on both top corners of the DIMM until the ejectors snap over the cutouts in the left and right edges of the DIMM.

2. Replace the system controller to the server (X4500).

4. Replace the cable management assembly if necessary.

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
1. Best is to fully monitor the BIOS startup to make sure all expected memory is present.
2. Bootup the OS
3. If the OS is Solaris, check fmadm/fmdump command outputs
4. Check total memory available and monitor error logs to check any new memory error messages
