3.8.5.2 Monitoring
Monitoring is ensured through:
• Autotests:
The various subassemblies of the iPBX (power supply unit, cards, main card functional
modules) include software or hardware self-monitoring devices; their condition is
broadcast to the central unit and triggers their resetting in case of fault, for CLX cards.
• Software watchdog on the UCV/UCV-D card
• Tachometric sensors for the fans, built into the power supply module and into the
ventilation module
• Temperature sensor built into the power supply module and ventilation module. When
the module’s internal temperature exceeds a certain threshold (fixed by the
manufacturer), an alarm is activated.
3.8.5.3 Alarm management
Alarm management is ensured by maintenance software present on the main card. The
alarms managed are those of the subassemblies in the iPBX, but also external alarms.
The main card collects the status of:
• Expansion cards
• Peripheral devices and links to the various cards
• Its modules and internal interfaces
• The iformation supplied by external sensors available to the customer (4 maximum).
A CLX card is declared faulty by the UCV/UCV-D in one of the following cases:
• If the card sends no reply
• If the card sends invalid replies.
A CLX card declared faulty is reset automatically by the UCV/UCV-D card then, if the fault
persists, deactivated.
A presence test is performed regularly by the UCV/UCV-D card on the equipment cards.
These are declared faulty when they no longer send replies or send an invalid identifier.
An anomaly detected in the configuration triggers the following:
• Recording of a fault report in the log
• A fail-safe action, initiated and executed by the maintenance software
• Recording of an action report message in the log.
The status of the subassemblies, centralised by the main card, can be viewed and
managed with the AMP, in the log.
