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

position.
