Applying Power to the Board

The Virtex-4 ML461 Development Board is now ready to power on. The Virtex-4 ML461

Confirm that the ON-OFF switch, SW4, is in the OFF position.
Plug the 5V desktop power supply into the 5V DC input barrel jack J9 on the Virtex-4
ML461 Development Board. Plug the desktop power supply AC line cord into an
electrical outlet supplying the appropriate voltage.
Turn SW4 to the ON position. The power indicators for all regulator modules should
come on, indicating output from the regulators. The System ACE status LED D9 comes
on when the System ACE controller (U36) extracts the BIT configuration file from the
CompactFlash card to the FPGA. If no CompactFlash card is installed in the card
socket J6 on the Virtex-4 ML461 Development Board, the red System ACE error LED
D11 flashes.
If a CompactFlash card is not installed in socket J6, a JTAG cable must be used to
configure the FPGAs. To use a Parallel Cable IV or other JTAG pod, download the
FPGA configuration bitstream into each FPGA. After the DONE LED (D1) comes on,
the FPGAs are configured and ready to use.
Eject the CompactFlash card from J6 after configuration is done and push the reset
button SW2.
