REMOVAL/REPLACEMENT INSTRUCTIONS

PROBLEM OVERVIEW: DIMM failure

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

A data backup is not a pre-requisite but is a wise precaution.
The customer should conduct an orderly software system shutdown.

 WHAT ACTIONS ARE REQUIRED:

Perform the following procedures to remove and replace a DIMM.

Caution – Use proper ESD grounding techniques when handling components. Wear an antistatic wrist strap and use an antistatic mat. Store ESD-sensitive components in antistatic bags before placing them on any surface.

Caution – When you remove and replace a single DIMM, an identical replacement is required. The replacement DIMM must be inserted into the same socket as the removed DIMM.

Caution – Each DIMM bank must contain at least four DIMMs of equal density (for example, four 128-Mbyte DIMMs) to function properly. Do not mix DIMM densities within any bank.

Caution – Handle DIMMs only by the edges. Do not touch the DIMM components or metal parts. Always wear a grounding strap when handling a DIMM.

Removing the DIMM

1. Power off the workstation, remove the access panel, and attach the antistatic wrist strap.

Caution – Use proper ESD grounding techniques when handling components. Wear an antistatic wrist strap and use an antistatic mat. Store ESD-sensitive components in antistatic bags before placing them on any surface.

2. Lay the workstation on its side.

3. Locate the DIMM(s) to be removed.

4. Press down the ejection lever at each end of the DIMM connector

5. Lift the DIMM straight out of the connector and set it aside on the antistatic mat.

Installing the DIMM

Caution – Do not remove any DIMM from the antistatic container until you are ready to install it on the motherboard. Handle DIMMs only by their edges. Do not

touch DIMM components or metal parts.

Note – For optimum memory performance, consider interleaving issues when installing DIMMs. See Section C.1.3.5, “System Memory Interleaving” on page C-14.

Caution – Use proper ESD grounding techniques when handling components. Wear an antistatic wrist strap and use an antistatic mat. Store ESD-sensitive components in antistatic bags before placing them on any surface.

1. Before installing a DIMM, review the following guidelines:

_ DIMMs are arranged in two banks, 0 and 1. Each bank has four connectors labeled “0” or “1”.

_ The workstation must have four or eight DIMMs installed to operate.

_ Each DIMM bank must contain four DIMMs of equal size to function properly.

For example four 128-Mbyte DIMMs in bank 0, four 256-Mbyte DIMMs in bank 1.

_ The default location for DIMMs installed at the factory is the four connectors labeled “0”

2. Remove the DIMM from the antistatic container.

3. Install the DIMM 

a. Align the notches on the DIMM with the memory connector.

b. Using your thumbs, press the DIMM straight down into the connector until the

ejection levers click, locking the DIMM in the connector.

Note – The DIMM is seated when you hear a clicking sound and the DIMM ejection levers are in the vertical position.

4. Detach the antistatic wrist strap, replace the access panel, and power on the Workstation

5. Verify proper operation.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTIONS ARE REQUIRED TO RETURN the SYSTEM TO AN OPERATIONAL STATE:

Restart software applications per applicable administration guides to resume system operation.
