A Pentium II Xeon processor upgrade kit includes the new Pentium II Xeon processor
Slot 2 SEC cartridge with attached heat sink.
Use the following procedure to add or replace a Slot 2 SEC cartridge.
NOTE: Dell recommends that only a technically knowledgeable person perform this
procedure.
Be sure the system board standby LED is turned off. If the standby LED is turned
on, the computer is not unplugged from its AC power source.
Unscrew and remove the four large thumbscrews and top bracket that secure the
heat sink and the Dell terminator card to the system board. Pull the terminator
card straight out to remove it from the connector. Be sure that the power require-
ments for both processors match. Otherwise, the CPU mismatch LED will light
up and the system will not turn on.
Unscrew and remove the four large thumbscrews and top bracket that secure the
heat sink to the system board. Grasp the Slot 2 SEC cartridge assembly firmly,
and pull it away from the guide bracket assembly (see Figure 9-8). You must use
up to 15 pounds (lb) of force to disengage the Slot 2 SEC cartridge from the con-
nector. Repeat this step if you are also replacing a second Pentium II Xeon
processor.
