Retension Modules - Intergraph InterServe 80 SL System Reference Manual

Retension Modules

Pentium II processors are secured to the system board using retension modules. See the
system board diagram in Chapter 5, "System Board," for connector and socket locations.
NOTE You do not need to replace a retension module to replace a processor module.
Retension module
To replace a retension module:
1. Remove the processor module. See the "Processor Modules" section above for details.
2. Remove the heat-sink locks, if necessary. See the "Heat-Sink Mounting Brackets"
section above for details.
3. Remove the screws securing the retension module to the system board, and remove the
retension module.
4. Locate the key pin on one end of the processor slot on the board. Carefully line up the
key notch on the new retention module with the key pin on the processor slot. The key
pin on the processor slot indicates the correct orientation of the CPU.
5. Lower the retention module down over the processor slot so that the retention module
seats flatly against the system board. Tighten the screws in a clockwise manner to
secure the module to the board.
WARNING Do not overtighten the screws as you may damage the module and/or the system
board.
6. Replace the heat-sink locks, if necessary. See the "Heat-Sink Mounting Brackets"
section above for details.
7. Replace the processor module. See the "Processor Modules" section above for details.
8. Replace the air duct using the two screws removed previously.
