Optional Extension Brackets
For this mainboard, you can also obtain an Optic module extension
bracket and a USB module extension bracket. Install them by
following the steps below.
Optic Module Extension Bracket
This bracket has two SPDIF jacks for digital audio in and digital
audio out, and an auxiliary jack for a stereo Line In device. It also
provides a pair of optic fiber interfaces which enable connection to
MiniDisk or high-end audio systems.
1. On the mainboard, locate the SPDF I/O header for this bracket.
2. Plug the cable from the bracket into the SPDF I/O header.
3. In the system chassis, remove a blanking plate from one of the
expansion slots and install the extension bracket in the slot.
Use the screw that held the blanking plate in place to secure
the extension bracket.
Internal Digital Audio
If you have an optional internal digital audio cable, you can also
use it to connect the digital audio output connector of a CD-ROM
or DVD-ROM drive to the pins 5-6 of SPDF I/O.
