Bus Termination Card
The bus termination card, MSMT379, is used only in systems with one processor. The card
provides termination for the processor bus. Single-processor systems will not operate without
the card installed. See the system board diagram in Chapter 5, “System Board,” for connector
and socket locations.
To replace the bus termination card:
1. Swing the power supply out of the chassis. See Chapter 1, “Accessing the System,” for
details.
2. Locate the bus termination card at J8, just below the primary processor.
3. Note the orientation of the card.
4. Grasp the top edge of the card at each end, and pull it straight out.
5. Remove the new card from its antistatic package, orient the card component side up, and
insert the card in the slot.
6. Press down firmly until the card is seated.
7. Swing the power supply back into the chassis and secure it with the plungers.
Processor Module
The replacement Pentium II processor is housed in a plastic module with heat sinks. The
processor module mounts in the dual processor retention module (DPRM). See the system
board diagram in Chapter 5, “System Board,” for connector and socket locations.
To replace the processor module:
1. Swing the power supply out of the chassis to expose the processor. See Chapter 1,
“Accessing the System,” for details.
2. Press the locking tabs on the top corners of the processor module inward, towards each
other, until they click into the release position.
3. Slide the processor module out of the DPRM.
4. Remove the new processor from its antistatic package, and align the processor module
over the DPRM. The processor module is keyed and fits only one way.
5. Press the processor module down until it seats.
6. Press the processor module locking tabs outward until they click into the locked position.
7. Swing the power supply back into the chassis and secure it with the plungers.
