enable position. This switch enables carrier clocking even if the Local
Carrier Interface card is not software enabled.
System monitors and alarms
System monitoring units continuously monitor the environmental and
power status of the system and the individual system modules including
the Carrier Remote IPE equipment.
The system monitor issues alarms when:
•
CPU fails or the system reloads
•
main power source is lost
•
power supply in the modules fails
•
system temperature exceeds limits due to blower or fan failure
System alarms are categorized for alerting and maintenance action on the
type and severity of faults reported by the system monitors and indicators.
These alarms are divided into:
•
major alarms, which indicate serious system problems that require
immediate attention
•
minor alarms, which indicate isolated faults relative to a limited number
of call connection problems that do not require immediate attention
Software diagnostic tools
System software diagnostic tools are used to monitor the system status,
provide the ability to test various system functions and equipment
suspected of being faulty, and log and display system fault history.
Diagnostic tools are:
•
resident diagnostic programs
•
interactive non-resident diagnostic programs
•
history file
•
user reports
Resident programs
System resident programs are diagnostic and administration programs
that continuously monitor system operation and report faults and generate
system messages, which are displayed on the system terminal or printed
on a system printer. These system messages are listed in the Software
Input Output Administration (NN43001-611) ().
