Boot-time LED Diagnostics
The front panel’s Status, Act 1 and Act 2 LEDs display the transition
through a sequence of codes at boot time indicating the SA8250’s
progress through the boot process. If the boot process aborts,
terminates, or hangs before the SA8250 is online and functional, the
state of the LEDs can help in diagnosing the problem. This table
describes the restart sequence and conditions.
After restart completes, the Status LED begins to blink and LED
activity begins as described in the next section, “Run time LED
Diagnostics.”
