Optional Extension Brackets

For this mainboard, you can also obtain a serial port extension
bracket and an Optic module extension bracket. Install them by
following the steps below.
Serial Port Extension Bracket
The mainboard has a header for an optional second serial port. You
can implement the second serial port by connecting this extension
bracket with a serial port to the onboard serial port header COM2.
1. On the mainboard, locate the header COM2 for this bracket.
2. Plug the serial cable into COM2.
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.
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.
