A Alarms
The Acme Packet 1100 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.
Table A-1 Descriptions of Alarm Severity Levels (cont.)
| 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 1100 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.
Hardware Temperature Alarm
The following table lists the hardware temperature alarm.
Table A-2 Hardware Temperature Alarm Information (cont.)
| Alarm Name | Alarm ID | Alarm Severity | Causes | Example Log Message | Graphic Display Window Message |
| TEMPERATURE HIGH | 65538 | CRITICAL: >100°C
MAJOR: >95°C MINOR: >90°C |
Fans are obstructed or stopped. The room is abnormally hot. | Temperature: XX.XXC
(where XX.XX is the temperature in degrees) |
Temperature X C (where X is the temperature in degrees) |
Fan Speed Alarms
The following table lists the fan speed alarm.
Table A-3 Fan Speed Alarm Information (cont.)
| Alarm Name | Alarm ID | Alarm Severity | Causes | Example Log Message | Graphic Display Window Message |
| FAN STOPPED | 65537 | CRITICAL: any fan speed is <50%.
MAJOR: speed of two or more fans is > 75% and < 90%. Or speed of one fan is >50% and <75% and the other two fans are at normal speed. MINOR: speed of one fan> 75% and <90%, the other two fans are at normal speed |
Fan failure. | Fan speed: XXXX XXXX XXXX
where xxxx xxxx xxxx is the revolutions per minute (RPM) of each fan on the fan module |
Fan stopped |
Environmental Sensor Alarm
The following table lists the environmental sensor alarm.
Table A-4 Environmental Sensor Alarm Information (cont.)
| Alarm Name | Alarm ID | Alarm Severity | Cause(s) | Example Log Message | Graphic Display Window Message |
| ENVIRONMENTAL SENSOR FAILURE | 65539 | CRITICAL | The environmental sensor component cannot detect fan speed and temperature. | Hardware monitor failure! Unable to monitor fan speed and temperature! | HW Monitor Fail |
Link and SDP Alarms
Link alarms are generated when a network cable is plugged into or unplugged from a configured network interface. For each possible network interface, an alarm exists that indicates whether the link goes up or down.
The following tables list detailed information about the Acme Packet 1100 link alarms, including their ID assignments, severities, causes, log messages, and messages printed in the graphic display window.
Media Ethernet Link Alarms
The following table lists the Ethernet interface link up/link down alarms.
Table A-5 Media Ethernet Link Alarm Information (cont.)
| Alarm Name | Alarm ID | Alarm Severity | Cause(s) | Example Log Message | Graphic Display Message |
| LINK UP ALARM | 131073 | MAJOR | S0P0 link up | Slot 0 port 0 UP | X LINK ALARMS (where X is number of alarming links) |
| LINK DOWN ALARM | 131074 | MINOR | S0P0 link down | Slot 0 port 0 DOWN | X LINK ALARMS |
| LINK UP ALARM | 131075 | MAJOR | S0P1 link up | Slot 0 port 1 UP | X LINK ALARMS |
| LINK DOWN ALARM | 131076 | MINOR | S0P1 link down | Slot 0 port 1 DOWN | X LINK ALARMS |
Management Ethernet Link Alarms
The following table lists the management Ethernet port alarms.
Table A-6 Management Ethernet Link Alarm Information (cont.)
| Alarm Name | Alarm ID | Alarm Severity | Cause(s) | Example Log Message | Graphic Display Message |
|---|---|---|---|---|---|
| LINK UP ALARM VXINTF | 131077 | MINOR | Mgmt0 link up | Port 0 UP | X LINK ALARMS |
| LINK DOWN ALARM VXINTF | 131080 | MAJOR | Mgmt0 link down | Port 0 DOWN | X LINK ALARMS |
In the Graphic Display Message column, the X denotes the number of alarming links.
