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.
