### Resetting PortServer

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

Important: You will lose all PortServer settings when you reset 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 PortServer.

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

3. Reboot PortServer.

4. If AC appears, reconfigure 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.

6. Contact Digi Technical Support.
