2.4 Errors and Alarms
Overview
Each output stage has its own status, error counter, alarm counter, GPI output, and SNMP trap
functionality. GPI_1 to GPI_6 are assigned to output stages 1 to 6, GPI_7 is assigned to the
spare output (or input). An SNMP trap which belongs to a certain output stage contains the
corresponding number.
The GPI outputs and SNMP traps can individually be enabled or disabled by configuration.
Additionally,
there are two overall counters: “
total number of errors
” and “
total number of
alarms
”. Any count value > 0 will be indicated by an LED or lamp at the module and/or by an
SNMP trap.
Errors
Any error detected on a signal always leads to the following error indications:
At the status monitor
•
The “
total number of errors
” counter shows the sum of all individual errors. A count value
of > 0 indicates that at least one error has been detected. Maximum value = 65,535.
•
Each output stage has its individual error counter. Maximum value = 65,535.
•
Each output stage has its individual status showing ‘
fail
’ in case of an error.
RUB1 modules, i.e. modules plugged to an H1, D1, Q1, S1, or T1 chassis
•
The LED in the “Error“ function lights up as long as the
“
total number of errors
” counter
has a count value > 0.
Depending on configuration an SNMP trap can be sent: An individual
Signal Failure
trap
and/or a
System Error
trap. Please notice section
