7. Verify that you are using the appropriate type of fiber optic cable and

that you have not exceeded the maximum operating distance. For
maximum operating distances and cable types, refer to “Fiber Optic
Port Specifications” on page 39.

8. Check that the operating specifications (e.g., wavelength and

maximum operating distance) of the fiber optic port on the end-node
are compatible with the operating specifications of the fiber optic port
on the media converter. Refer to “Fiber Optic Port Specifications” on
page 39 for more information.

Link Test

To check hardware reliability of the media converter, perform the following
procedure:

1. Power OFF the PC chassis where the media converter is installed.

1. Connect the RJ-45 twisted pair port to a 100Base port on an end-

node, such as an Ethernet switch, and power ON the end-node.

2. Using a tested and good fiber patch cable, attach the matching ends of

the fiber cable to the transmit (TX) and receive (RX) connectors of the
media converter and the opposite ends to a second end node with a
compatible 100 MB fiber port. Power ON the end-node.

3. Configure the media converter for Link Test and re-install the media

converter in the PC. See “Configuring MissingLink & Link Test” on
page 28 for more information.

4. Power ON the PC chassis where the media converter is installed.

5. Verify that the PC is powered ON and has booted up successfully.

6. Verify that the LINK LED on both the twisted pair and fiber optic ports

are green.

7. If the LEDs are green, the unit is working properly and there is a

problem elsewhere on the segment.

8. If the LEDs are OFF, contact Allied Telesis Technical Support.
