Figure 17.

Caution!
Do NOT plug a PC ATX power supply 6-pin connector into J49 on the AC701 board
The ATX 6-pin connector has a different pinout than J49. Connecting an ATX 6-pin connector into
J49 will damage the AC701 board and void the board warranty.
To avoid loose contact issues, make sure the connections are secure. Turn ON the SW15
switch, apply power to the system, insert the Fedora LiveDVD, and change the boot
order to boot from the DVD.
Check the status of the design using the AC701 board LEDs. The design provides
status with the GPIO LEDs located on the upper right portion of the AC701 board.
When the PC is powered on and the TRD has successfully configured, the LED status
from left to right indicates:
• LED position 1: ON if DDR3 is calibrated
• LED position 2: ON if the lane width is x4, else flashing
• LED position 3: Heart beat LED, flashes if PCIe user clock is present
• LED position 4: ON if the PCIe link is up
