Troubleshooting

100M LED

If the 100M LED for the port does not indicate the correct speed, check the

following:

❑

If the port is auto-negotiating, wait 1-3 seconds after the device cable

is connected, or power is applied, for the negotiation process to

complete.

❑

If Port 8 is used as an “Uplink”, check that the cable length used for

an uplink does not exceed 5 meters (16 feet) in an 100 Mbps

configuration.

❑

For Ports 1 and 2, check that the speed is correctly set on the DIP

switch. If necessary, adjust port speed on Ports 1 and 2 by manually

setting the DIP switches before connecting other devices.

Connectivity Testing

The following procedure tests each port for a valid connection and correct

operation of the network.

1. Power OFF the unit.

2. Starting with Ports 1 and 2, set the DIP switch (on the back of the unit) to

the appropriate configuration. Refer to “Station Connections” on page 10.

Connect these two ports of a single unit to two nodes or workstations and

apply power to the hub.

3. Make sure the

Link/Activity

and other LEDs of both hub ports are lit. If

the port is auto-negotiable, wait approximately 1-3 seconds for the process

to complete after power is applied or after the cables are reconnected.

4. After confirming that Port 1 and Port 2 are operational, reconnect one of

the nodes/workstations to another port, then repeat this communications

test with the hub’s remaining ports. Continue to verify the connection on

each port by checking the

Link/Activity

and other LEDs of both hubs.

Note

When testing Port 8 connection to a workstation, set the uplink

switch to the

Normal

position.
