Fallback Reference (daxClockFallbackRef)
The fallback reference enables the configuration of a back-up clock reference should the main reference fail.
The
Main Reference
and
Fallback Reference
parameters have the same selections for system clock. Make sure
you choose different clock sources for the Main Reference and Fallback Reference. The fallback reference set-
tings are the same as those described in section “Main Reference (daxClockMainRef )” on page 42.
Clock Status (daxClockFailure)
The clock status indicates alarm conditions relating to the system clock. If there are no alarms, the Clocking
page will indicate
No Alarm
(see figure 15 on page 42). If an alarm condition exists, an
Alarms Present
message
will be displayed along with one of the following failure descriptions.
•
no-failures(0)—No alarms present
•
main-ref-fail(1)—The main clock reference has failed
•
fallback-ref-fail(2)—The fall back clock reference has failed
