150 Upgrading Boardset Components
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

See Figure 53.
1. Observe the safety precautions, warnings, and cautions at the beginning of this chapter.
2. Remove the top cover (see “Removing the Top Cover” on page 98).
3. Remove the processor holddown bracket and set it aside.
4. Simultaneously rotate the eject/insert levers of the terminator module outward to eject the
module out of the Slot 2 connector.
5. Slide the module out of the processor retention bracket slot guides, and place it component-
side down on a nonconductive, static-free surface.
