8. Replace the air duct beneath the power supply, using the screws you removed previously.
9. Connect the power cables to the system board and internal devices. See Chapter 7,
“Power Supply and Cooling Fans,” for connection details.
Bus Terminator
The bus terminator card is used only in systems with a single processor. The card provides
termination for the secondary processor bus. Single-processor systems will not operate
without the card installed. See the system board diagrams in Chapter 5, “System Board,” for
connector and socket locations.
To replace the bus terminator card:
1. Locate the bus terminator card in the secondary processor slot.
NOTE The card is keyed to prevent incorrect insertion.
2. Grasp the top edge of the card at each end, and pull it straight out.
3. Remove the new card from its antistatic package, orient the card the same was as the old
card, and insert the card in the slot.
4. Press down firmly until the card is seated.
Processor Modules
TDZ 2000 GL2 and ExtremeZ GL2 systems are compatible with 266, 300, 333, 350, and 400
MHz Pentium II processors. See the system board diagram in Chapter 5, “System Board,”
for connector and socket locations.
To replace a passive processor module:
1. Remove the heat-sink lock from within the heat-sink fins, if necessary, by pressing the
ends of the lock inward and pulling outward.
2. Press the locking tabs on the top corners of the processor module inward, towards each
other, until they click into the release position.
3. Slide the processor module out of the retension module.
4. Remove the new processor from its antistatic package, and align the processor module
over the retension module. The processor module is keyed and fits only one way.
