17.2 LED’s on Thermal Hub a nd Mainboard.
On the Thermal Hub boa rd and the Main board, there are several LED’s which will illuminate if a failure occurs on the board. It is
primarily the different voltages on the boards which are monitored, but also some other control parameters. The table and figures
below show the failure matrix and the location of the different LED’s.
