3.Are Channel Links Good?

If the T-LNK LED for a twisted pair port is OFF:

•Ensure the network device connected to the twisted-pair channel port is powered ON.

•Ensure that the twisted-pair cable is connected securely both to the channel port and to the network device.

•If the network device connected to the port is a workstation, ensure that the cable is in the crossover configuration.

•If the network device connected to the port is a hub or switch, ensure that the cable is in the straight-through configuration.

•Ensure that the network device connected to the port is operating at correct speed: 10 Mb/s or 100 Mb/s.

If the F-LNK LED for a fiber optic port is OFF:

•Ensure that the network device connected properly to the fiber-optic port is powered ON.

•Ensure that the fiber-optic cable is connected to the fiber- optic port and to the network device.

•Ensure that the network device connected to the fiber-optic port is operating at correct speed: 10 Mb/s or 100 Mb/s.

•Set the Link Test switch(es) to TEST position (to isolate fiber link faults from faults on the twisted-pair network).

Allow 5-10 seconds for all devices to link-up. All LNK LEDs should illuminated

NOTEL Remember to reset Link Test switch(es) to NORMAL after procedure is completed

•Verify that the maximum allowable loss budget on the fiber- optic cable is within acceptable limits.

If a LINK LED of a port is illuminated but there is a communication problem with the port:

•Ensure that the duplex setting is set the same on the nodes connected to the twisted-pair and to the fiber-optic ports of the media converter channel.

If all LNK LEDs are OFF but all network decices and fiber-optic cable are connected, a link-up problem is suspected:

•Contact TRANSITION Networks Technical Support.
