Alarms
The Acme Packet 4500 generates internal alarms that correspond to internal
hardware fault conditions. Hardware faults are divided into two types:
•
Hardware and environmental
• Media link
Each alarm is assigned a severity level, depending on the details of the fault. Refer to
the following table for information about these alarms.
Table 6 - 8. Alarm Severity Levels Described
Alarm Severity Description
Minor Functionality is impaired to a small degree (e.g., a single fan has failed).
Major Pending failures or unexpected events are imminent (e.g., an LOS).
Critical Catastrophic condition has occurred (e.g., the system is overheating).
The Acme Packet 4500 polls its hardware components to ensure they are functioning
properly. If it encounters a fault condition, it will report alarms in these categories:
• Hardware temperature
•
Fan speed
• Environmental sensor
•
Power supply
• Voltage
•
Physical interface cards
For each category, the following tables list the Acme Packet 4500 alarm name,
