5. Insert the new SEC cartridge/heat sink assembly into the system board
connector.
Press the SEC cartridge firmly into its connector until it is fully seated and the
latches snap into place. You must use up to 25 lb of force to fully seat the SEC
cartridge in its connector. Install or replace the two large thumbscrews that
secure the heat sink to the system board.
6. If necessary, change the processor speed jumper setting (see Figure B-1 to
locate system board jumpers).
The processor speed jumper should be set for the installed microprocessor’s
rated internal speed. For example, for a 450-megahertz (MHz) Intel Pentium II
processor, a jumper plug should be installed on the pins labeled “450MHZ.”
(See Appendix B, “Hardware Configuration Features,” for more information
on the jumpers.)
7. Rotate the power supply back into position, making sure that the securing tab
snaps into place.
