Backplane & LEDs
A functional / operational backplane will illuminate three solid RED LEDs. See picture below.
One solid green LED on the backplane signifies “standby mode”. The magma device is” switched off” on the
electronic interface (but it draws some power) on standby mode. It is waiting to be activated by a remote power or
remote controller.
See picture below.
IMPORTANT
If the above three RED LEDs are not coming ON, you may be having a faulty power supply unit or
defective backplane
