3. When powered up:
a) Blue front panel LED remains illuminated as long as power is applied to the board (via the
AdvancedMC backplane connector).
b) Ethernet port activity LEDs switch on to indicate any Ethernet link to the front or back planes.
c) The "System Status" LED, LD507, switches on, then goes off once system configuration is
complete. LED LD506 should stay on indicating the processor is "Ready."
d) Any USB UART activity is shown on LEDs D507 and D508.
4. Pressing the power cycle button (SW2) power cycles the board and start the reset sequence.
5. Pressing the reset button (SW3) starts the reset sequence only.
