AT-30xxSL Multiport Repeaters
11
Using an external transceiver
1. Connect an AT-210T transceiver or AT-210TS transceiver to the
repeater’s 15-pin AUI port.
2. Make sure that the transceiver’s Signal Quality Error (SQE)/Heartbeat
test function is disabled.
When the repeater is powered on, the transceiver should also be
receiving power.
3. Attach one end of a straight-through UTP cable to the transceiver’s
10Base-T receptacle, and the other end to Port 1, as shown in Figure 8.
4. Make sure that the MDI/MDI-X switch is set to the MDI-X position
(crossover).

5. Check for valid LED settings:
❑ LINK (Port 1) should be lit on the repeater side of the connection.
❑ The Link LED on the AT-210T or AT-210TS should also be lit.
6. 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.
Using 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 LINK
LEDs are lit.
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 secure network connections.
