Troubleshooting

This chapter describes the procedures to test and troubleshoot the hub.

Connectivity Testing

In the following procedure, you will test each port for a valid connection and to

confirm the correct operation of the network.

1. Start with Ports 1 and 2. Connect these two ports of a single hub to two

nodes or workstations and turn on the hub’s power supply.

2. Make sure the Link/Activity and other LEDs of both hub ports are lit.

3. 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 in each port by checking the Link/Activity and other

activity LEDs.

Note

When testing the 100 Mbps ports with Port 1 connected to a workstation,

set the button

position.

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

complete after power-on or after the cables are reconnected.

4. When cascading hubs using port 1, set the uplink slide switch to the
