DISPATCH INSTRUCTIONS
- WHAT SKILLS DOES THE ENGINEER NEED: Nothing beyond basic hardware and Solaris training
- TIME ESTIMATE: 30 minutes
- TASK COMPLEXITY: 0

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW:How to Remove and Replace a Ultra 40 M2 Workstation Memory DIMM
- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?:

Caution: DIMMs are installed in adjacent pairs. However, if you replace a single DIMM, the new DIMM must be identical to the DIMM that you removed.
Caution: Handle the DIMMs along the outside edges. Do not handle the DIMM along the gold contact edge. Do not touch DIMM components or other metal parts. Always wear an antistatic wrist strap when handling DIMMs.

Sun Ultra 40 memory is installed as pairs of DDR400 PC3200 Registered ECC DIMMs. Sun Ultra 40 M2 memory is installed as pairs of DDR2-667 DIMMs.

The DIMMs in a pair must be identical, from the same manufacturer with the same type and number of memory devices, the same amount of memory per device, and the same memory speed. All installed DIMMs must have the same memory speed.

* The minimum configuration is two 512-Mbyte DIMMs installed in slots 0 and 1.

* Connector slots 0, 1, 2, and 3 are for CPU0, and 4, 5, 6, and 7 are for CPU1. However, the second CPU does not require installed DIMMs. The workstation will operate with only two DIMMs installed in CPU0, even if it has two CPUs.

* DIMMs should be installed in the following order:

Caution: The Ultra 40 and Ultra 40 M2 DIMMs are numbered the same but located differently, and this difference is critical. On the Ultra 40, DIMM slots 0/1 and 4/5 are closest to their respective CPUs. On the Ultra 40 M2, DIMM slots 0/1 and 4/5 are farthest from their respective CPUs. See FIGURE 5-4 and FIGURE 5-5 respectively. The slot color coding and provisioning rules are the same.

The DIMM connectors on the motherboard are color-coded blue and black:

o Single-CPU systems:

0/1 (black)

2/3 (blue)

o Dual-CPU systems:

0/1 (black)

4/5 (black)

2/3 (blue)

6/7 (blue)

o A single-CPU system cannot have DIMMs in any CPU1 slot (4 through 7).

o Memory should be evenly split across CPUs in a 2 CPU configuration or all on CPU0 in a 1 CPU configuration.

o Larger DIMM pairs go into the lower DIMM slots first.

1 GB : 2 x 512 MB : Standard (Ultra 40 only)

2 GB : 2 x 1 GB : Standard

4 GB : 4 x 1 GB : Standard

8 GB : 8 x 1 GB : Optional

16 GB : 8 x 2 GB : Optional

32 GB : 8 x 4 GB : Optional

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Power off the system, open and position the chassis, and remove the access panel.

I. Power off and disconnect the monitor, keyboard, mouse, network connections, and any peripherals.
II. Disconnect the power cord from the workstation.
III. Press down the two latches on the side cover and lift the cover off the workstation.
IV. Using both hands, place the workstation on its side.
V. Pivot the workstation support leg underneath the workstation.
VI. Remove the access panel:
a. Slide the lock block to the front of the system.
b. Press and release the two latches and lift the access panel.
VII. Attach the antistatic wrist strap.
VIII. If your procedure requires it, lift the fan module up and out.
IX. Find the removal or replacement procedure you need.

Removing the DIMMs

I. Open the memory cooler (Ultra 40 M2 Only) :
a. Squeeze the latch until it releases.
b. Raise the housing to expose the DIMMs.
II. Release the DIMM by simultaneously pressing down on both ejector levers at the ends of the DIMM slot.
III. Lift the DIMM straight out of the DIMM slot.

Caution - Handle the DIMMs along the outside edges. Do not handle DIMMs along the gold edge. Do not touch DIMM components or other metal parts. Always wear an antistatic wrist strap when handling DIMMs.
Caution - Do not lift the DIMM out of the DIMM slot at an angle. This can damage the edge connector for the DIMM or the DIMM slot.

IV. Set the DIMM aside on an antistatic mat.
V. Repeat Step II through Step IV until you have removed all relevant DIMMs.

Installing the DIMMs

DIMMs should be installed in the following order. Note that the DIMM connectors on the motherboard are color-coded blue and black:
Caution - The Ultra 40 and Ultra 40 M2 DIMMs are numbered the same but located differently, and this difference is critical. On the Ultra 40, DIMM slots 0/1 and 4/5 are closest to their respective CPUs. On the Ultra 40 M2, DIMM slots 0/1 and 4/5 are farthest from their respective CPUs.

o Dual-CPU systems:

4/5 (black)
2/3 (blue)
6/7 (blue)

* A single-CPU system cannot have DIMMs in any CPU1 slot (4 through 7).

* The DIMMs in a pair must be identical; they must be from the same manufacturer, with the same speed and the same architecture.

* All DIMMs in the system must have the same speed.

Before installing memory, verify that the latest version of BIOS, system firmware, and recommended system patches are installed on your system.

Caution - Use proper ESD grounding techniques when handling components.

I. Power off the system, open and position the chassis, and remove the access panel.
II. Remove the new DIMM from its antistatic container.
III. Review the recommended DIMM installation and configurations before installing the DIMM.
IV. Align the DIMM notch to the DIMM connector key.
V. Using both thumbs, press the DIMM straight down into the DIMM connector slot until both ejector levers close, locking the DIMM in the DIMM connector slot.
VI. Repeat Step IV through Step V until all DIMMs are installed.
VII. Verify that the DIMM ejector levers are upright, seated, and tight.
VIII. Close the memory cooler
IX. Install the side cover and the access panel.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
AN OPERATIONAL STATE: Power on the system, and verify the installation
