### Checking LED Indicators: OFC On?

Use this procedure when an OFC indicator light is on on the PortServer.

Note: This Procedure only works with a PortServer and not a PortServer II. PortServer II users should choose Back to return and continue with the Master Troubleshooting Process.

Procedure

1. From a terminal attached to the port, enter:

> `Ctrl-Q`

2. From the PortServer, enter:

> `kill tty=port number`

> where `port number` is the number assigned to the PortServer.

3. If OFC is still on, enter the following at the PortServer command line prompt:

> > `who`

> If the Connected from column shows other items such as IP address, make sure that the originating system process is disabled.

> If in either case, the lights are still on, choose Back to return and continue with the Master Troubleshooting Process.
