KB01114 - Performance Issues after loading firmware for AT-UHD-SW-52ED onto an UHD-SW-52 or vice-versa


Symptom: Incorrectly loading AT-UHD-SW-52 firmware on the AT-UHD-SW-52ED or vice versa

  • Since the SKU’s are similar and products look alike, it’s possible to accidentally load the incorrect firmware on the AT-UHD-SW-52ED
  • Common way to diagnose this is if you have lost IR control on the SW-52ED or SW-52
  • Logging into the WebGUI won’t allow you to load the correct firmware


  • Connect to the switch via Telnet or RS232
  • Send the “Mreset” command (followed by a carriage return).

This should reset the unit and should give you the ability to load the correct FW via the WebGUI.

  • Try reloading firmware again through the web-interface
  • After loading correct FW, send the Mreset command again to reboot the unit.

This should resolve the issue and allow the unit to function again.
