IEEE 1394a

The IEEE 1394 expansion cable bracket is provided in the box but if you do

not require the additional external connections, you do not need to install it.

1. Secure the bracket to either the front or rear panel of your chassis (not all

chassis are equipped with the front panel option).

2. Connect the two ends of the cables to the IEEE 1394 connectors on the

motherboard.
