Installing the Processor Board
1. Be careful not to touch components or gold edge
connectors on the processor/memory board as you
remove it from its protective wrapper. Place board
component-side up on an antistatic surface. If you
need to set any of the processor board configuration
jumpers, refer to the Configuring System Board
Jumpers section in the Configuring Your System
chapter.
2. On the system board, locate the processor board
connector (Figure 5-6).
3. Hold the processor board (see Figure 5-6, D) by its
edges and start to insert it into the slot guides.
4. Do not press in on the board yet! Ease board into the
slot guides until it is just touching the connector on
the system board.
Caution: Before pressing the board firmly into the
system board connector, confirm visually that the board
edge connectors are correctly oriented—not too low or
high—at the system board connector.
5. Press the board carefully but firmly into the system
board connector to seat the board.
Caution: Before applying power, do one more check.
Make sure the board is completely seated in the system
board connector before applying power. Incomplete
insertion can result in damage to the system board and
to the board you have installed.
6. Replace the board support panel as described earlier
in this chapter, see Installing a Board Support
Panel.
7. Replace the side panel and turn on the power.
