The Individual Errors and Consequences of Errors
The following errors will be indicated at the
Reference
page of the status monitor:
Chapter ‘
Overview of Error Indications at the Status Monitor
’ describes the mean
ing of
status
,
counts
,
fail
, and
disabled
.
pps timeout
Signal loss at the PPS input: no valid PPS detected since 1.6 s.
pps timing
PPS signal disturbance: the interval between two consecutive PPS signals does not
correspond to one second
serial timing
Serial data string at RXD IN either is lost or is not synchronized with the PPS
signal.
serial sequence
A time discontinuity has been detected while checking the time & date infor-
mation of the serial data string. This leads to an error even at a valid time
discontinuity in case of a leap second or a DST switching if a local time zone has
been selected as reference.
Each error has the following consequences:
•
Indication of an error at the status monitor (‘
status
’ = 1).
•
Error counter counts one up.
•
Counter ‘
overall errors
’ counts one up.
•
LED programmed as ‘
Switcher Error’
lights up (RUB1 version modules).
•
GPO output
programmed as ‘
System Error
’ becomes active.
•
SNMP trap ‘
System Error
’ will be sent.
Each error has additional the following consequences if the corr
esponding ‘
disable
’ checkbox
has not been checked:
•
Indication of a failure at the status monitor (‘
fail
’ = 1).
•
Counter ‘
overall failures
’ counts one up.
•
Lamp programmed as ‘
Fail’
lights up (RUB1 version modules).
•
GPO output
programmed as ‘
System Failure
’ b
ecomes active.
•
SNMP trap ‘
System Failure
’ will be sent.
•
The log file of an Ethernet module receives an entry.
Each ‘
current sequence
’ error produces an entry in the log file of an Ethernet module.
