Installing the Motherboard
Caution – The system supplies power to the motherboard even when the system is
powered off. To avoid personal injury or damage to the motherboard, you must
disconnect all AC or DC power cables before servicing the motherboard.
1. Align the motherboard with the chassis so the CPU cage sits directly behind the
hard drives and fan trays (
FIGURE 4-40

2. Lower the motherboard into the chassis at an angle, inserting the CPU side of the
board first.
Ensure that the DVD cable and the SCSI cable are folded back out of the way. You
might have to rock the motherboard from side-to-side to install it cleanly.
