MMC: 851
ALARM REPORTING
DESCRIPTION:
This MMC is used to view, store, print or clear system alarms. There are two levels
of faults displayed via alarm code, major alarms and minor alarms. Major alarms
codes are usually service affecting and require a certified technician to determine
the fault. A minor alarm indicates a fault that may or may not be service affecting
and usually does not seriously degrade the systems operating capabilities. The
alarm buffer will hold up to 100 alarms on a first in - first out (FIFO) basis. Alarms will
provide a date and time stamp based on the system time. If applicable the hardware
cabinet, port, and/or slot will be displayed. If an ALARM SIO port is programmed
(MMC 804) alarm information can be printed on demand and also prints as alarm
information is provided.
✳
System Alarm Reporting is only available on a system with a LAN module
installed on the MCP card.
