4.3 Alarm Signal Flow
The detection of failures in the outdoor SPI-2210 can be implemented by hardware
interrupt or software polling method. The failures generated in the outdoor SPI-2210 are
reported to the management system via the SNMP trap message.
Failure Alarm Types
 System Failure Alarms
Time Sync Fail, Fan Fail, Temperature High, etc.
 Board Failure Alarms
 Hardware Failure Alarms: BOARD DELETION, FUNCTION FAIL, etc.
 Software Failure Alarms: COMMUNICATION FAIL, PORT DOWN, CPU
OVERLOAD, OVER POWER, etc.
 UDA
24 UDAs are supported.
 Environmental alarm via UCM
Failure Report Message Flow
The main OAM (UFM) collects the failures detected from each board and UDA interface
of the outdoor SPI-2210 and notifies them to the management system. At this time, it only
reports the upper failure information by using the failure filtering function. If it receives the
command to inhibit the report for a specific failure or all system failures from the
management system, it does not report the failure report.
The flows for the failure detection and the report message are as shown in the figures below:
