Overview of Error Indications and Alarms in General
This module detects errors on the word clock signals, on signals of the real-time reference, or
on the module itself after a self-test.
Basically, each individual error will be represented by a status, an error counter, and an
indication of a failure. The indication of a failure can be disabled. If not disabled, special
alarms can be raised in case of an error. This gives the user the possibility to select individual
errors for an alarm indication.
Furthermore, two overall counters are giving a quick overview:
•
The “
overall errors
” counter
shows the sum of all individual errors. A count value of > 0
indicates that at least one error has been detected.
•
The “
overall failures
” counter
shows the sum of all individual failures, i.e. all those errors
with the failure indication not disabled. A count value of > 0 indicates that at least one
failure has been detected.
You can see all the individual errors and both overall counters at the status monitor. Please
open the status monitor to investigate the source of an error.

RUB1 modules, i.e. modules plugged to a 1 RU chassis, indicate errors by the ERROR LED and
failures by the FAIL lamp (in the default configuration):
•
The LED in
the “Switcher Error“ func
tion
lights up as long as the “
overall errors
” counter
has a count value > 0.
•
The lamp/key
in the “Fail“ function lights up as long as the “
overall failures
” counter has
a count value > 0.
