- Now the power switch -SW10 can be changed to ON- position.
4.
When power is applied to the EVB, three orange LED’s adjacent to the voltage regulators show the presence of the supply
voltages as follows:
•
LED D34
Indicates that the 12.0V is connected to the EVB correctly.
•
LED D35
Indicates that the 5.0V linear regulator is enabled and working correctly.
•
LED D36
Indicates that the +3.3Vlinear regulator is enabled and working correctly.

– Power supply Input and LED power indicators
If no LED’s are illuminated when power is applied to the EVB and the regulators are correctly enabled using the appropriate
jumpers, it is possible that either power supply is not connected properly, or the voltage level is lower that the specified [+12.0V
to
≥2Amps].
Note that the fuse will not protect against one of the EVB regulators being shorted. If this happens, damage is likely to occur to
the EVB and / or components.
5. The board is ready to use now.
