Performing a cold reset (to factory defaults)
Once you configure the print server, the configuration settings are retained in memory
unless you manually reset them to factory defaults, as follows:
1. Unplug the power module from the back of the print server.
2. While holding down the test button on the back of the print server, plug the power
module back into the print server and continue to hold down the test button for
about five seconds. Any user-configured settings will be erased.
