Chapter 2: Upgrading Baseboard Components
Installing a Processor
Use Figure 2-6 and the following steps when installing a new or additional processor.
Note: If your system has less than four processors and you are adding one, then you
must remove the termination board in the empty Slot 2 connector. The procedure for
removing a termination board is the same as for removing a processor.
If you plan to reduce the number of processors in your system, then you must replace a
processor with a termination board. The procedure for installing a termination board is
the same for installing a processor.
1. Read and observe all the safety and ESD precautions at the beginning of Chapter 1.
2. Remove the new processor from its antistatic package and place it on a grounded,
static-free surface or conductive foam pad.
3. Orient the S.E.C. cartridge so that the heat sink faces away from the center of the
baseboard.
If you are installing a termination board, orient it so that the side with the white
bar-code label faces away from the center of the baseboard.
4. With the tabs at the top of the S.E.C. cartridge completely open (pulled outward,
away from the center of the cartridge), slide the cartridge into the guide rails of the
retention module. When done properly, the triangular ends of the tabs (with two
round pegs on each) fit into the entrance to the guide rails.
5. When the cartridge meets resistance, push the two tabs toward each other until the
processor is fully seated.
6. Reattach the retention module bracket:
■ With the bracketin an open position (perpendicular to the front of the retention
module), slide the open hinge at the left of the bracket into its receptacle at the
left of the retention module.
■ Rotate the bracket to the right until it reaches the retention module. With your
right thumb on the face of the bracket and your right index finger around the
tab at the right of the bracket, slightly pull the tab outward and to the left to
open the latch at the back of the tab.
■ As you open the latch on the back of the tab, slide the right edge of the bracket
onto the retention module and release the tab. If done correctly, the bracket will
be securely latched.
