Rear Panel Installation Procedure (Option 203 only)
1 Install the Channel 3 assembly as follows:
2 Remove the T20 TORX screw at the rear of the motherboard.
3 Connect one end of the supplied 40-pin ribbon cable to J900 on the
motherboard. Connect the other end to J401 on the underside of
the Channel 3 circuit board.
4 Set the Channel 3 assembly down on top of the motherboard so
that the female SMA edge connector is towards the rear panel.
The front flange on the right-front of the Channel 3 assembly
bracket must rest on the tab protruding from the front panel (see
Figure 4-22).
Figure 4-22. Channel 3 assembly installed on top of the motherboard,
with the female SMA edge connector pointing toward the rear.
5 Install the supplied SMA semi-rigid cable as follows:
6 Insert the end of the semi-rigid cable with the female SMA
connector through the hole on the rear panel marked "Opt
106/115". Secure the connector with the supplied 5/16" hex nut and
lockwasher. Finger-tighten only.
