6. Insert the new SEC cartridge/heat sink assembly
into the system board connector.
Press the SEC cartridge release latches outward until
they snap into position. Orient the assembly with the
heat sink facing the left side of the chassis, and 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.
7. Replace the airflow shroud over the processor(s).
Fit the mouth of the shroud into the alignment slot on
the left side of the fan and between the fan and the

both pairs of tabs on the top of the shroud and lower
it down until the clips on the bottom of the shroud
engage onto the top of the processor heat sink(s).
8. 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 266-megahertz (MHz) Intel Pentium
II processor, a jumper plug should be installed on the
pins labeled "266MHZ." (See Appendix B, "Hard-
ware Configuration Features," for more information
on the jumpers.)
