3Com 5101T-FB-ST manual Verifying Physical Link Operation, To verify physical link operation

There are differences between IEEE 802.3 and Ethernet Version 2.0 AUI cables. While the 10BASE-FB Transceiver is compatible with both, ensure that the AUI cable being used is appropri- ate for the device being connected. Refer to the section, AUI Cables and Pinouts, later in this manual for cable specifications.

Note: The AUI cable can not exceed 50 meters in length.

Verifying Physical Link Operation

To verify physical link operation:

1.Verify that every transceiver on the network has its status indicator ON and not blinking.

2.Verify that each 3Com 10BASE-FB Sta Coupler or Ethernet 10BASE-FB Module port status indicator is ON and not blinking.

If after completing Steps 1 and 2 you find no blinking Status indicators, you can now use your network nodes and verify data connectivity.
