DIMMs
See the section, “Adding Memory,” in Chapter 3, “Upgrading the System,” for important
details on handling DIMMs. The DIMM sockets are located just below the power connectors
P1 and P2 on the system board. See the system board diagram in Chapter 5, “System Board,”
for connector and socket locations.
To replace a DIMM:
1. Swing the power supply out to expose the DIMM sockets. See Chapter 1, “Accessing the
System,” for details.
2. Press the release tabs outward, away from each other.
3. Grasp the top edge of the DIMM and pull it out of the socket.
4. Remove the new DIMM from the antistatic package.
5. Orient the DIMM so that the notches match the keys in the socket.

6. Insert the DIMM straight down into the socket.
7. Push gently straight down until the release tabs snap into place.
8. Swing the power supply back into the unit and secure it with the plungers.
System Board
You must swap the DIMMs, bus termination card (if installed), and processor module(s) from
the old system board to the new one (MSMT589). See the system board diagram in Chapter
5, “System Board,” for connector and socket locations.
Note that a number of Fastex fasteners are mounted in the right side of the chassis to secure
the system board and dual processor retention module (DPRM) supports. Do not overtighten
the screws to these fasteners. If overtightened, the fasteners may distort.
