Install the Extension Brackets
The extension brackets are used to transmit features on the
mainboard to external connectors that can be fixed to the system
chassis. Follow the steps below to install the extension brackets.
Note:
All the ribbon cables used on the extension brackets carry a
red stripe on the pin-1 side of the cable.
Fax/Modem DAA Module
The Fax/Modem DAA module plugs directly into the mainboard
adjacent to an expansion slot in the system chassis. When you
remove the blanking plate from the system chassis, you can access
the LINE and TEL RJ11 phone jacks on the metal edge of the Fax/
Modem DAA module.
