P6 Bus Termination Card
The P6 bus termination card, MSMT311, is used only in systems with the MSMT353 or MSMT359
system board that has one or two processors. Refer to Chapter 5, “System Board MSMT353 and
MSMT359,” for details.
To replace the P6 Bus termination card:
1. Open the base unit.
2. Remove the installed PCI cards. The termination card is attached to the system board adjacent to
the memory modules.
3. Remove the screws securing the termination card to the system board.
4. Carefully disengage the card from the system board and remove it.
5. Attach the new card to the system board, and secure the card with the screws.
6. Replace the PCI cards.
7. Close the base unit.
Processor Module for MSMT353 and MSMT359
The replacement processor module, MSMT364 or MSMT310, for the MSMT353 and MSMT359
system board, includes pre-installed voltage regulator modules(VRMs) and processors.
To replace the processor module:
1. Open the base unit.
2. Remove the installed PCI cards. The processor module is attached to the system board adjacent
to the memory modules.
3. Remove the left VRM to access mounting screw.
4. Remove the screws securing the processor module to the system board.
5. Carefully disengage the module from the system board and remove it.
6. Attach the new processor module to the system board, and secure it with the screws.
7. Reinstall the left VRM.
8. Replace the PCI cards.
9. Close the base unit.
Processor Module for MSMT378
The Pentium Pro and Pentium II processors for the MSMT378 system board are housed in plastic
processor modules, which have heat sinks attached to one side. When a Pentium II module is
installed into an S1 slot, the heat sinks are supported at the bottom by a black plastic bar, which runs
between the two bottom-most rows of heat sink fins. The support bar is connected to a support
assembly via four posts.
