How to replace memory on a Sun Blade X8440 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 X8440 Server Modules use 1.8V error-correcting (ECC) high-capacity dual inline
memory modules (DIMMs). The DIMMs are built with double-data-rate-two
synchronous dynamic access memory (DDR2 SDRAM) that operates at a 667-MHz
clock frequency.

The X8440 Server Module supports up to 32 DIMMs, eight per CPU in the following
capacities:
■ 1-Gbyte
■ 2-Gbyte
■ 4-Gbyte

The maximum memory capacity for the X8440 Server Module is 128 Gbytes (4 CPUs
x 8 DIMMs per CPU x 4 GB DIMMs = 128 Gbytes total).

Memory Module Configuration and Population Order
TABLE 2-1 identifies the recommended memory configuration and population rules.

Each X8440 CPU supports up to 8 DIMMs
• All X8440 DIMMs must be populated in pairs, for example:
•2-DIMM = DIMM pair 3 (DIMM slots 6 and 7 installed)
•4-DIMM = DIMM pairs 2 and 3 (DIMM slots 4, 5, 6, and 7 installed).
•6-DIMM = DIMM pairs 1, 2, and 3 (DIMM slots 2, 3, 4, 5, 6, and 7
installed)
•8-DIMM = DIMM pairs 0, 1, 2 and 3 (DIMM slots 0, 1, 2, 3, 4, 5, 6,
and 7 installed
• If the X8440 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 6 and 7.
• All X8440 DIMM pairs must be identical with respect to manufacturer,
size and speed.

▼ 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. Remove the blade cover.

Note – Some X8440 Server Modules are shipped with tool-less covers. If the X8440
Server Module does not have screws holding the cover in place, refer to the
instructions for removing a tool-less cover.

• If the X8440 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 6 and 7.
• All X8440 DIMM pairs must be identical with respect to manufacturer,
size and speed.

c. 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.
Type of Cover Description Screws holding cover in place
Using a Phillips screwdriver, remove the four middle cover screws and
fully loosen the four captive screws.
Tool-less cover Locate the green release levers. Then, using your fingers push the levers
inward to release the cover.

4. Locate and unpack the new DIMM 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.
