Copper Transceivers
Copper transceivers are also available for the Acme Packet 4600 System. They are
removed and replaced similarly to the optical transceivers.
Alarms
The Acme Packet 4600 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.
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 4600 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
Important:
If different sensors report two or more events of the same severity with the
same Alarm ID, only the first alarm gets reported.
Hardware and Environmental Alarms
This section provides details about hardware and environmental alarms.
