Our service staff reported that when powered up, the D9 and D10 were blinking and RDY led is on steady, none of the other leds ERR, BUSY were on
That means the UCM was working
The UCM has been upgraded to the latest version
If any frmware upgrade operation fails, especially for Ethernet when connection is lost, the firmware upgrade should be repeated without resetting the UCM or Comfort. If the UCm or comfort is reset the firmware becomes corrupted and the RDY, BUSY1, BUSY2, ERR leds will be permanent on
