SNMP Device MIB

This page briefly describes the content of the Vingtor-Stentofon MIB.

Simple Network Management Protocol (SNMP) is an Internet-standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.
Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and more.

A Management Information Base (MIB) is a database used for managing the entities in a communication network.
Most often associated with the Simple Network Management Protocol.

temp OID

Only ENA2x00 and ESC1 devices has temperature sensors implemented and will report temperature values in this object identifier.

All reported temperature values is 10 times the real value, i.e. reported value 355 is 35.5 C and should be adjusted accordingly by the NMS before presented to the observer.

1.     tempTableCount shows the number of temperature sensors reported and viewed in the tempTable, i.e. 5 for ENA2x00 and 4 for ESC1.

2.     tempTable contains the items for temperature reporting.

2.1.  tempIndex internal identifier.

2.2.  tempSensorName shows the temperature sensor name, device dependent.

2.3.  tempCurrentString, fixed text “Current Temperature” to identify current temperature item.

2.4.  tempCurrentValue shows the current (last measured) temperature value. Temperatures for ENA2x00 ranges typically from 30.0 C to 75.0 C and is highly dependent on audio level, load and which temperature sensor measured. Temperatures for ESC1 ranges typically from 25.0 C to 40.0 C and will probably be more affected by the ambient temperature than the ENA2x00.

2.5.  tempPeakString, fixed text “Peak Temperature” to identify peak temperature item.

2.6.  tempPeakValue, shows the peak (highest measured) temperature since device was booted. Peak temperatures for the ENA2x00 ranges from typically 35.0 C to 75.0 C, although higher temperatures may be reported. Peak temperatures for the ESC1 ranges typically from 30.0 C to 40.0 C.

2.7.  tempAverageString, fixed text “Average Temperature” to identify average temperature item.

2.8.  tempAverageValue shows the average value of the last 8 measured current temperatures and will slowly follow the value in the tempCurrentValue and lags approx. 20 seconds after tempCurrentValue.

For ENA2x00 the following actions will be carried out based on the current value of any of the 5 temperature sensors:

·        If the temperature on any of the sensors rises above 36.0 C both fans will start to run and will not stop running until the temperature on all sensors falls below 32.0 C for minimum 30 seconds.

·        If the temperature on any of the sensors rises above 50.0 C, both fans will rotate at their maximum speed and will continue at maximum speed until the temperature on all sensors falls below 45.0 C.

·        If the temperature on a sensor rises above 65.0 C a warning level message of type “Warning High” is generated and will not be cleared until the temperature on that sensor falls below 60.0 C. The warning message will be auto-cleared from the system when the temperature on that sensor falls below 60.0 C.

·        If the temperature on a sensor rises above 83.0 C a warning level message of type “Alarm High” is generated and will not be cleared until the temperature on that sensor falls below 78.0 C. The warning message will be auto-cleared from the system when the temperature on that sensor falls below 78.0 C.

ENA2200 and ENA2400:

·        If the Class D chip internal temperature sensor rises above approx. 125.0 C an alert level (crit) message of type “Graceful Degradation” is generated and will not be cleared until the temperature on the internal temperature sensor falls below approx. 110.0 C. Graceful degradation in this context means lowered audio output to self-protect the device from over-heating. The only way to remove the alert message from the system is to acknowledge the alert message and manually clear it on the ESC1 if it previously has been auto-cleared locally on that specific device.

ENA2400:

·        If the DC Power temperature sensor rises above 100.0 C an alert level (crit) message of type “Graceful Degradation” is generated and will not be cleared until the temperature on the DC Power temperature sensor falls below 90.0 C. Graceful degradation in this context means lowered audio output to protect the DC Power unit from over-heating and subsequent power shutdown. The only way to remove the alert message from the system is to acknowledge the alert message and manually clear it on the ESC1 if it previously has been auto-cleared locally on that specific device.

·        The AC Power temperature sensor is unused (at the time of writing) and is reported as 0 C.

For ESC1 the following actions will be carried out based on the current value of any of the 4 temperature sensors:

·        If the temperature on any of the sensors rises above 41.0 C the fan will start run and will not stop running until the temperature on all sensors falls below 35.0 C for a minimum 30 seconds.

·        If the temperature on any of the sensors rises above 55.0 C, the fan will rotate at its maximum speed and will continue at maximum speed until all sensors falls below 49.0 C.

·        If the temperature on a sensor rises above 65.0 C a warning level message of type “Alarm High” is generated and will not be cleared until the temperature on that sensor falls below 60.0 C. The warning message will be auto-cleared from the system when temperature falls below 60.0 C.

ampChannel OID

This OID will report the present status of the amplifier channel output(s), that is if the channel is operative (OK) or in any way disabled or impaired.

Only ENA2x00 and Exigo panels and kits based on 8121 or 8124 will report status to this OID although the panels and kits will only report “channelOK” or “unknown” in the ampChannelStatus field. The ENA2x00 devices will report all possible statuses as defined in the ampChannelStatus OID in the MIB.

1.     ampChannelCount shows the number of amplifier channel outputs reported and viewed in the ampChannelTable and will vary according to model type.

For ENA2x00 the ampChannelStatus identifies the following statuses:

·        “unknown” means the OID has not been updated with data from the monitoring software.

·        “notOperative” means the amplifier output has been set in “Disabled” mode either by the operator from the ENA2x00 GUI or is configured as “Disabled” from EMT.

·        “channelOk” means the amplifier output is on and working as intended.

·        “channelFail” means the monitoring software has detected a hardware related fault. This fault can for instance be the “Ready” signal from the Class D amplifier chip not responding as expected.

·        “channelShutdown” means the Class D amplifier chip has been overloaded for up to 5 times within a time-slot of 15 seconds. The overloaded amplifier output is set in “Shutdown” mode by the monitoring software and the output is “Disabled” (as in off) and reported as “Channel Shutdown” to the ESC1 system controller. Only manual operation on the local GUI on the ENA2x00 amplifier can clear the “Shutdown” mode and bring the amplifier output back into normal operation.

Note: Future versions of the ENA2x00 firmware may have an EMT selectable “channel shutdown auto-clear” option which, when enabled, will try to bring the amplifier output on and operative without manual interference.

·        “channelGracefulDegradation” means either the Class D chips internal over-temperature self-protect circuitry has been activated (120.0 C) or any of the two the external temperature sensors adjacent to the Class D chip has reach the “Graceful Degradation” temperature (100.0 C). The amplifier will reduce audio output to self-protect the device. Once the temperature is below the safe temperature limit (90.0 C) the amplifier will resume normal output levels.
