FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: Memory Failure/Fault

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 ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE?:

SIMMs

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

Caution – When removing a SIMM, an identical replacement is required. The
replacement SIMM must be inserted into the same socket as the removed SIMM.

Caution – Each SIMM bank must contain at least two SIMMs of equal density (for
example, two 32Mbyte SIMMs) to function properly. Do not mix SIMM densities in
any bank.

Note – The system unit must have at least two identical SIMMs installed in paired
sockets of any SIMM bank. For best system performance, install four identical
SIMMs.

Bank     Bank Quad
0          U0701, U0702, U0703, and U0704
1          U0801, U0802, U0803, and U0804
2          U0901, U0902, U0903, and U0904
3          U1001, U1002, U1003, and U1004

To Remove a SIMM

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

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

1. Attach the wrist strap.

2. Power off the system and remove the input power connector(s).

3. Remove the top access cover.

4. Remove the power supply but do not disconnect any restraining power supply
cables.

5. Rest the power supply on the side of the system enclosure.

6. Locate the SIMM to be removed.

7. Push the lever away from the SIMM

8. Remove the SIMM from the socket.

9. Place the SIMM on an ESD mat.

To Replace a SIMM

Caution – SIMMs are made of electronic components that are extremely sensitive to
static electricity. Ordinary amounts of static electricity from clothing or work
environment can destroy the SIMM.

Caution – Do not remove any SIMM from the antistatic container until ready to
install it on the motherboard. Handle SIMMs only by their edges. Do not touch
SIMM components or metal parts. Always wear an antistatic wrist strap when
handling SIMMs.

Caution – Each SIMM bank must contain two SIMMs of equal density (for example,
two 32Mbyte SIMMs) to function properly. Do not mix SIMM density in any bank.

1. Attach the wrist strap.

2. Locate the appropriate SIMM slot(s) on the motherboard.

Note – The system unit must have at least two identical SIMMs installed in paired
sockets of any SIMM bank. For best system performance, install four identical
SIMMs.

Caution – Hold SIMMs only by the edges.

3. Remove the SIMM from the antistatic container.

4. Position the SIMM in the socket, ensuring that the notch is on the same side as
the lever.

5. Using your thumbs, press firmly on the top of the SIMM until it is properly
seated.

Note – Proper SIMM seating is verified by a clicking sound. Ensure the SIMM is
properly seated.

6. Replace the power supply.

7. Replace the top access cover.

8. Power on the system.

9. Detach the wrist strap.
