Power-On Self-Tests
The Avid Adrenaline runs power-on self-tests (POSTs) to determine if the box
and the boards within the box are operating properly each time you turn it on.
If a failure occurs during the POST, specific Avid Adrenaline status LEDs on
the front panel (see the following figure) light to help you determine which
board within the Avid Adrenaline is not functioning properly.
Avid Adrenaline Status LEDs
The following table shows the failure codes presented on the LEDs that define
passing and failing during POST, and which specific board has failed.

If no LEDs are lit 10 seconds after you turn on the Avid Adrenaline, the Avid
Adrenaline has not yet reached the capability of running diagnostics and
should be considered nonfunctional.
When a failure occurs in the POST, both the high-definition (HD) and
standard-definition (SD) LEDs are lit and the DV and NTSC LEDs define the
failing board. The PAL and REF LEDs might be on or off. For more
information on the LEDs, see
“Front Panel” on page 6 .
