When I power up my rack, the Aurora doesn't come on until I hit the power button. Why is that?

The default power-up state for the Aurora is "standby". With firmware revision 11 or later, this can be changed so that "On" is the power-up state. This mode is toggled by holding the standby switch while power is applied. PLEASE NOTE: After the mode is changed the unit must be put into standby mode to save this setting before power is removed.
