How to replace memory on a Sun Blade X8400 Server Module

Add Memory Modules to the Server Module
The Sun Blade server modules are shipped with standard memory configurations.
If you ordered additional memory, a kit for the additional memory is shipped separately.
About Memory Modules

The X8400 Server Module uses 2.5V error-correcting (ECC) high-capacity dual inline
memory modules (DIMMs). The DIMMs are built with double-data-rate
synchronous dynamic access memory (DDR SDRAM) that operates at a 400-MHz
clock frequency.

Memory capacities available include:
■ 1-Gbyte
■ 2-Gbyte
■ 4-Gbyte

Memory Module Configuration and Population Order

TABLE 2-1 Memory Module Configuration and Population Rules

Server Module Memory Module Configuration Rules X8400

• Each X8400 CPU supports up to 4 DIMMs

• All X8400 DIMMs must be populated in pairs, for example:

•DIMM pair 0 = DIMM slots 0 and 1. These DIMM slots are the
farthest slots from the respective CPU.

•DIMM pair 1 = DIMM slots 2 and 3. These DIMM slots are the
nearest slots to the respective CPU.

• If the CPU has only a single DIMM pair, then you must install that
single DIMM pair into the farthest slot locations from the respective
CPU, which are slots 0 and 1.

Memory Module Installation
Before installing additional memory on the server module, you will need to gather
the following items:
■ Antistatic wrist strap and mat
■ Sun Blade server module
■ Memory kit

Follow these steps to add memory modules to a server module.
1. Locate and unpack the server module from its antistatic packaging.
Caution – Do not use the ejector latches to carry the server module. The ejector
latches should only be used to seat the server module in the chassis. They are not
designed to support the weight of the server module.

2. Remove the server module cover by performing the following steps:
a. Place the server module on a stable, antistatic work surface.
For example, place the server module on top of an antistatic mat; or, place the
server module on top of the server module’s plastic packaging.
b. Slide the cover up until the cover clears the tabs at the front of the server
module, then remove the cover.

3. Locate and attach the antistatic wrist strap.
Follow instructions provided with the wrist strap.

4. Locate and unpack the new from its antistatic container.

5. Ensure that the DIMM ejector levers are open (angled outward) then align the
DIMM notch to the DIMM connector key.

6. 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.

Note – The DIMMs must be inserted evenly, straight down into the DIMM
connector slot, until the ejector levers lock into place.

7. Verify that the DIMM ejector levers are upright, seated, and tight. Press on the
ejector levers to ensure that they are engaged properly.

8. To install the second DIMM, repeat Steps 4 through 7.

9. To reinstall the server module cover, slide the cover under the tabs at the front
of the server module, then reinstall and tighten all screws.
