Testing You should check the Port OK LED for each 10BASE-T port that is being
used. ON indicates a valid link. There are two methods for doing this:
One method uses a transceiver connection to the AUI port
1. Connect an AT-210T Transceiver to the repeater’s AUI port.
Attach one end of a straight-through UTP cable to the transceiver’s
10BASE-T receptacle, and the other end to Port #1; make sure the
MDI/MDI-X switch is set to the MDI-X (crossover) setting (see
Figure 4).
2. Check for valid LED settings:
— Port OK #1 should be lit on the repeater side of the connection.
— The Link LED on the AT-210T should also be lit.
3. Leaving the transceiver connection intact, connect the other end of the
cable in turn to each of the other 10BASE-T ports and check the LEDs.
The other method uses existing network devices
1. Establish a network connection from Port #1 to a network device (such as
a server) and from Port #2 to a workstation. Make sure both Port OK
LEDs are lit.
2. After a successful connection, disconnect the active 10BASE-T connector
from Port #2 and connect it to the next successive port (i.e., Port #3).
Continue until all 10BASE-T ports have been validated with good
network connections.
