Troubleshooting

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

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 switch to two
nodes or workstations and turn on the switch power.

2.

Wait approximately 1-3 seconds for the auto-negotiation process to
complete after power-on or after the cables are reconnected.

3.

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

4.

After confirming that Port 1 and Port 2 are operational, reconnect one of
the nodes/workstations to another port, then repeat this connectivity test
with the switch’s remaining ports. Continue to verify the connection in
each port by checking the Link/Activity and other activity LEDs.

Note
Use Port 8 MDI-X connected to a workstation. Use Port 8 MDI
connected to a hub. Use only one Port 8 at a time.
