10 ALARMS
10.1 GENERAL
In this document is present a description of alarms in order to help operators to perform equipment trou-
bleshooting.
10.2 ALARM SYSTEM
There are two ways to identify the alarms:
•through LEDS
• through SCT/WebLCT
For each part of SIAE radio system, groups of alarms are defined. These alarms can be independent or
interdependent with each other, according to the real causes that generated them.
Alarms are divided into 4 severity levels according to the effects that an alarm might cause to the regular
operation of the unit detecting it. Levels are prioritised as follows:
• Critical (red): out-of service, hw failure, urgent alarm
• Major (orange): loss of signal, minimum residual functionality, urgent alarm
• minor (yellow): failure neither urgent, high residual functionality, not urgent alarm
• warning (light blue): indication or wrong configuration, not urgent alarm
• none (green) no alarm or masked alarm.
Critical and Major alarms indicate impossibility of executing a service, hence the faulty units needs to be
serviced. Minor level represents the not urgent alarms which do not prejudice service continuity.
Warning level indicates malfunctions that might be locally removed without having to replace the unit.
Alarm severity can be modified or masked in “alarm severity configuration” via SCT/WebLCT by the oper-
ator.
