Installation. To install the front-panel cable, refer to Figure 8--3 and follow these
steps:
1. Connect the front-panel cable to the front-panel module at J1 through the
appropriate slot on the chassis.
2. Twist the cable to keep it from contact with the boards and chassis, and
secure using the right cable tie.
NOTE. Wind up the front-panel cable until it is tight; loops are okay. This keeps
the cable bundle together.
3. Connect the front-panel cable at J202 on the main board by pushing the cable
straight down into the connector.
4. Install the five screws to attach the front panel module to the chassis.
You will need a torque-limiting Torx T-15 long shank screwdriver, a torque
wrench, and a 5/8 inch deep socket for this procedure.
CAUTION. The main board module is particularly sensitive to ESD. Read the
Preventing ESD section on page 6--1 before removing or installing the main
board.

these steps:
1. Remove the power button and rear case using the procedures on page 6--9.
2. Remove the internal assembly from the front case using the procedure on
page 6--12.
3. Disconnect the following wires from the main board by pulling straight up
from the connector:
H The power supply cable at J101. Press down on the latch while pulling
up on the cable.
