Self-Test Failure
LED
Operational Status
LEOs
Summary: Interpreting
the
LEOs
The self-test runs when the computer power is switched on or the
PCA
is reset.
The self-test failure LED goes on during execution of the self-test (which takes
less than five seconds), and will go off when the self-test passes.
If
the self-test
fails, the self-test failure LED will remain on, and you must replace the
PCA.
If
the
PCA
self-test completes successfully, the self-test failure LED will turn off
and remain off. Subsequently, under firmware control, the
PCA
will begin
operation. In this mode, the interpretation of the LEDs is summarized in
table 3-1 and described below.
In table 3-1, the bold
type
in the status column shows the acceptable state(s) of
the LED in question. Entries in normal-weight type designate a fault. The
self-test failure LED must be off for this information to be accurate.
