Front Side Bus Terminator Module; Removing A Terminator Module; Reinstalling A Terminator Module - Intel AC450NX Product Manual

Front Side Bus Terminator Module

The CPU baseboard provides four slot 2 connectors for processors packaged in S.E.C. cartridges.
If any slot 2 connector is depopulated, a terminator module must be installed in the connector to
properly terminate the signals on the front side bus (FSB). For example, if only two slots are
populated with processors, you need FSB terminator modules in the two unpopulated processor
slots. The terminator modules are housed in plastic covers.

Removing a Terminator Module

See Figure 13-5.
1. Observe the precautions on page 115, "Safety Guidelines."
2. Remove the top cover as described in Chapter 12, "Server Covers: Removing/Reinstalling."
3. Loosen the holddown bracket captive screw and remove the holddown bracket.
4. Simultaneously rotate the eject/insert levers of the terminator module outward to eject the
module out of the slot 2 connector on the CPU baseboard.
5. Slide the module out of the slot guides, and place it component-side down on a nonconductive,
static-free surface.

Reinstalling a Terminator Module

See Figure 13-5.
1. Grasp the terminator module by the eject/insert levers, and carefully slide it into the slot guides
until the levers engage with the flanges in the front sides of the guides.
2. Simultaneously rotate the levers inward until they are flush with the edge of the module to seat
the module into the slot 2 connector on the CPU baseboard.
3. Insert the hook end of the holddown bar in the flange of the right slot guide.
4. Tighten the captive screw.
5. Reinstall the top cover as described in Chapter 12.
