KB01388 - How to reset a AT-UHD-SW switch


Subject: How to factory reset the AT-UHD-SW switch


  • Connect to the switch via its local RS232 - For information on how to create a DB9 to barewire cable, please see this article. For information on how to use a serial emulator, see this article
  • Send the “Mreset” command (followed by a carriage return).
  • Hard power cycle (remove the powersupply) the unit for 30 seconds

Please note, factory resetting the unit will re-enable all the factory settings on the unit. This will also clear any existing network address assignments and use DHCP. Please see this article for information on how to connect to the UHD-SW's web-GUI.
