5.5 Alarm Characteristics

Units Alarms:
Each port card or access card of the equipment is provided with a bicolor LED (green/red) on the front
coverplate.
This LED indicates:
– when red, internal failure
– when green, in service unit
Centralized Equipment Alarms:
All the alarms detected on the units are collected by the EC320 unit which will deliver centralized optical
indications (by means of LEDs on its front coverplate). Specifically:
• Red LED (13): detection of an CRITICAL alarm
• Red LED (14): detection of an MAJOR (URGENT) alarm
• Orange LED (15): detection of a MINOR (NOT URGENT) alarm
• Orange LED (16): detection of an WARNING (INDICATIVE) alarm
• Red LED (17): alarm condition ATTENDED
• Orange LED (18): detection of an ABNORMAL operative condition. Type: active loopbacks,
forcing the unit into service, laser forced ON or OFF, try to restore after ALS
Refer to Figure 19. on page 47, where the front view of each unit and the LED locations are illustrated.
Rack lamps and Remote Alarms:
Some equipment alarms are carried to a connector, for customer applications, such as lighting-up of alarm
lamps (rack-lamps) or to drive a custom-alarms interface. Rack alarm and Remote Alarm are physically
available on connectors placed at the top of the subrack back panel (refer to Figure 16. on page 44).
The available alarms are the following:
Rack lamps alarms:
• RL_RURG: urgent alarm
• RL_RNURG: not urgent alarm
• RL_RATTD: alarm storing
Remote alarms:
• RA_URG: detection of an urgent alarm (from EC320)
• RA_NURG: detection of a non-urgent alarm (from EC320)
• RA_INT: detection of an Internal alarm (from EC320)
• RA_ORC : fault or loss of service battery (OR) (from EC320)
• RA_IND: Indeterminate alarm. It indicates synthesis of alarms not associated to the other
severity (from EC320)
• RA_ORBATT: fault or loss of one battery station (from POW320)
• RA_ANDBATT: loss of both battery station (from POW320)
