System Board
i.LINK Connectors
The system board has two i.LINK (IEEE-1394) connectors: a 4-pin connector is accessible from the front panel, and a 6-pin connector is accessible from the rear panel. Use the front-panel connector to connect to devices that use a 4-pin i.LINK (IEEE-1394) connector. Use the rear-panel connector to connect to devices that use a 6-pin*i.LINK (IEEE-1394) connector.

*A 6-pin i.LINK connector can supply power from the computer to the device if the device also has a 6-pin i.LINK connector. A 4-pin i.LINK connector cannot supply power to a device.
