Alarms by SNMP Traps
SNMP functionality for a RUBIDIUM system requires the installation of an Ethernet module
(
RUB IE
or
RUB PM
) with option
S
(SNMP).
Utilizing one of the configuration tools, the SNMP traps can be enabled and disabled at the
System
page (please refer to chapter
‘
”
System
”
: Identification, Reset, SNMP, Fan Control
’
).
The “Any Trap” checkbox in genera
l controls the SNMP traps functionality. Furthermore, there
are checkboxes corresponding to all the individual traps.
Recommen
ded configuration: Check the “Any Trap” and “System Failure” checkboxes.
This chapter describes all the alarm functions for traps. The following feature is valid for all
these traps: As long as the alarm condition is present, traps will be repeated in an 8 hours
interval.
Signal 1 Failure / Signal 2 Failure
Check the “Signal Failure“ checkbox
Trap will be sent as long as there is any major word clock error at
CLOCK IN 1
or
CLOCK IN 2
respectively. In detail, this trap will be sent if one of the following errors has
occurred and this error has been enabled to indicate a failure (checkbox “
disable

not
checked):
signal loss
frequency
signal to pps drift
Please refer to chapter
‘

’
for a detailed error description.
Word Clock Warning

System Error
Check the “System Error“ checkbox
Active, as long as the “

The error indication cannot be disabled, so this trap will be sent in case of any error, i.e.
word clock/real-time reference/self test errors.
System Failure
Check th
e “System Failure“ checkbox
Active, as long as the “
overall failures
” counter has a count value > 0.
Any individual errors can raise this alarm provided this error has been enabled to
indicate a failure (checkbox “

not checked). Depending on this configuration,
word clock/real-time reference/self test errors may activate this trap.
