Altera Cyclone II DSP Development Board - Manual (Page 77)

Altera Corporation Reference Manual 2–69
August 2006 Cyclone II DSP Development Board
Cyclone II DSP Development Board Components
Power Plane Connectors (J2-J6, J39 Through J42)
Bench power supplies provide an easy way to measure the current draw
on each power plane. When one plane is being powered by the bench
supply, all other planes still draw current from the DC power input. Upon
applying power to the Cyclone II DSP development board, the power
LED (D1) should be on.
Table 2–36 lists the procedure for powering individual planes through
bench power supplies. In the instructions, only remove the fuse listed in
the Settings column. Other fuses should be left on Cyclone II DSP
development board.
