Installation and Maintenance Manual - Aastra 5000 AMT/PTD/PBX/0058/4/6/ENDescription et caractéristiques d’un PBX 01/2011 Page 1033.8.5.2 MonitoringMonitoring is ensured through:• Autotests:The various subassemblies of the iPBX (power supply unit, cards, main card functionalmodules) include software or hardware self-monitoring devices; their condition isbroadcast 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 theventilation module• Temperature sensor built into the power supply module and ventilation module. Whenthe module’s internal temperature exceeds a certain threshold (fixed by themanufacturer), an alarm is activated.3.8.5.3 Alarm managementAlarm management is ensured by maintenance software present on the main card. Thealarms 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 faultpersists, 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 andmanaged with the AMP, in the log.
