### Resetting a PortServer

Use this troubleshooting procedure when AC does not display on your PortServer and you need to reset the PortServer to the factory defaults.

Important: You will lose all PortServer settings when you reset your PortServer to factory defaults. If you have a complex configuration, call Digi Technical Support for assistance.

#### Procedure

1. Power on while simultaneously pressing both arrow buttons on the front of the PortServer.

2. Hold these buttons down until EP is displayed on a PortServer I or CL is displayed on a PortServer II.

3. Reboot the PortServer.

4. If AC appears, reconfigure the PortServer.

5. If AC still appears, choose Back to return and continue with the Master Troubleshooting Process.

If AC doesn't appear, make note of the status of the LED display on the front of the PortServer and contact Digi Technical Support.
