To determine if the computer’s IEEE 1394 system is functioning properly, perform the

following procedures. Figure 2-14 outlines the process. Start with Procedure 1 and continue

with the other procedures as instructed.

Procedure 1: IEEE 1394 device check

Procedure 2: Diagnostic check

Procedure 3: Connection and replacement check

Procedure 1

IEEE 1394 device check

Connect an IEEE 1394 device to the computer’s IEEE 1394 port, then boot the computer for
Windows Vista. The computer should automatically detect the 1394 device. Check whether
the device can transmit data to the computer.

If the device is able to communicate with the computer, the problem may be intermittent or
connections may be faulty. Go to Procedure 2.

If communication is impaired, there may be a faulty connection. Go to Procedure 3.

Procedure 2

Diagnostic check

Run the Diagnostic Program, which will automatically execute the IEEE 1394 port test for
transmission. Refer to Chapter 3, Tests and Diagnostics for more information on how to run
the program.

If an error is located, go to Procedure 3. If an error does not occur, the 1394 port is
functioning properly.

Procedure 3

Connection and replacement check

The transmission cable may be damaged or the connections may be loose. Perform Check 1:

Check 1

Make sure the transmission cable is firmly plugged into both the IEEE 1394-
compatible device and the IEEE 1394 port of the computer. If the cable is
connected correctly, go to Check 2.

Check 2

Make sure the IEEE 1394 port is firmly secured to the system board of the
computer. If the malfunction persists, go to Check 3.

Check 3

The transmission cable may be damaged. Replace with a good cable. If the
malfunction persists, go to Check 4

Check 4

The system board may be damaged. Replace it with a new one following the
instructions in Chapter 4.
