Upgrading Your System 4-29
Front Side Bus (FSB) Termination Board
Assembly
The profusion carrier provides connectors for two processor mezzanine boards.
Each board provides four Slot 2 connectors for Pentium III Xeon processors
packaged in S.E.C. cartridges. If any Slot 2 connector is depopulated, a
termination board assembly must be installed in the connector to properly
terminate the signals on the FSB.
For example, if only two slots in a mezzanine board are populated with
processors, you need FSB termination board assemblies in the two unpopulated
processor slots.
The assembly is a termination board packaged in plastic housing.
Removing a Termination Board
1.
Observe the safety precautions, warnings, and cautions at the beginning of
this chapter.
2.
Remove the top cover following procedures previously described in this
chapter.
3.
Remove the processor holddown bracket and set it aside following
procedures previously described in this chapter.
4.
Simultaneously rotate the eject/insert levers of the terminator module
outward to eject the module out of the Slot 2 connector. See Figure 4-18.
5.
Slide the module out of the processor retention bracket slot guides, and place
it component-side down on a nonconductive, static-free surface.
Installing a Termination Board
1.
Grasp the terminator board by the eject/insert levers, (A) and carefully slide
it into the slot guides of the processor retention bracket until the board stops.
See Figure 4-18.
2.
To seat the board in the mezzanine board connector, push down on the
levers simultaneously, making sure that the lever locks (B) engage with the
slots of the processor retention bracket flange (C).
3.
Insert the hook end of the holddown bracket in the flange of the processor
retention bracket. See Figure 4-16.
4.
Insert the screws you removed earlier and tighten them firmly (8.0 inch-
pounds).
5.
Install the top cover.
