P-660HN-T1H User’s Guide

Refer to the Quick Start Guide for information on hardware connections. 

If you forget your password or cannot access the web configurator, you will need 
to use the RESET button at the back of the device to reload the factory-default 
configuration file. This means that you will lose all configurations that you had 
previously and the password will be reset to “1234”. 

Make sure the POWER LED is on (not blinking).

To set the device back to the factory default settings, press the RESET button for 
ten seconds or until the POWER LED begins to blink and then release it. When the 
POWER LED begins to blink, the defaults have been restored and the device 
restarts.
