Connectivity Testing
Follow the steps outlined below to test for a valid connection as well as to
confirm the correct operation of the network.
1. Connect port 1 and port 2 of a single AT-MR908TX to two nodes or
workstations and turn on the hub power supply by connecting the AC
power cord.
2. Check to make sure the Link/Activity LEDs of both port 1 and port 2 are
illuminated.
3. After confirming that port 1 and port 2 are operational, remove the power,
reconnect one of the computers to another port, turn the power back on,
then repeat this communications test with all of the ports.
Note
When testing the cascade port (Port 1), connect the port to a computer
and select MDI-X using the MDI/MDI-X slide switch.
4. Verify the connection in each port by checking the Link/Activity LED and
performing the communications test as described in steps 2 and 3.
5. Once each port of a single AT-MR908TX hub has been tested, check the
connection between computers of two different AT-MR908TX hubs (if your
configuration has more than one hub). When cascading repeaters, always
select cascade mode on one repeater by using the MDI/MDI-X slide switch
to select MDI.
