DISPATCH INSTRUCTIONS

WHAT SKILLS ARE REQUIRED:

No special skills required, Customer Replaceable Unit (CRU) procedure

TIME ESTIMATE: 30 mins

TASK COMPLEXITY:  0

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW: Memory 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:

Caution – For maximum performance, the DIMMs in this system have been
specifically designed for it. Do not use DIMMs from a different system to upgrade or
replace the DIMMs in this system. Verify with your Sun sales or service
representative that the DIMMs you order have been Sun-certified for this system.

A failed DIMM can be identified by the address displayed in a memory failure error
message, or in POST.

Caution – DIMMs consist of electronic components that are extremely sensitive to
static electricity. Ordinary amounts of static electricity from clothing or work
environment can destroy the DIMM.

Removing a DIMM

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

1. Power off the system, remove the system cover, and attach an 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.

Note – Always remove and replace DIMMs in order, beginning with the DIMM
closest to the edge of the motherboard.

2. Locate the DIMM to be removed.

3. Push the ejection levers at each end of the DIMM connector away from the DIMM

4. Lift the DIMM straight up from the motherboard connector.

5. Place the DIMM on an antistatic mat.

Replacing a 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. Always wear an antistatic wrist strap when
handling DIMMs.

Note – Always remove and replace DIMMs in order, beginning with the DIMM
closest to the edge of the motherboard. The system will not function
properly with only three installed DIMMS. You must install either one DIMM, two
DIMMs, or four DIMMs.

1. Remove the DIMM from the antistatic container.

2. Position the DIMM in the connector, ensuring that the notches on the bottom of
the DIMM are aligned with the connector alignment keys

Note – DIMM alignment notches and connectors are keyed to ensure proper DIMM
orientation.

Caution – If the DIMM is not seated into its slot evenly, it can cause electrical short
circuits that will damage the system. Ensure that all contacts engage at the same
time by pressing evenly on both ends of the DIMM—do not rock the DIMM into
place. When the DIMM is properly seated, you should hear a click.

3. Press firmly on the top ends of the DIMM at the same time until the DIMM is
properly seated.

4. Verify that the ejection levers are closed toward the DIMM.

5. Detach the wrist strap, replace the system cover, and power on the system

OBTAIN CUSTOMER ACCEPTANCE
