What Is SNR-ERD-3s?
SNR-ERD-3s is an enterprise MIB for the NAG SNR-ERD-3s environmental relay device, a network-attached appliance used to monitor environmental sensors and drive relay/contact outputs for alarm and remote-control purposes. It belongs to the facility/environmental monitoring technology area and exposes data on IP-level device identity (ipAddress, ipGatewayAddress, ipMonitoringDevice), configured trap destinations, sensor-triggered alarm contacts, and remote relay control contacts along with cumulative alarm/reset counters. Its monitoring value is squarely in facility/hardware fault detection: tracking monitorAlarmSignal1Contact8 and monitorAlarmSignal2Contact9 for dry-contact alarm inputs (e.g., door, smoke, or equipment sensors), monitorAnySensorSignal1contact5/contact6 for generic sensor triggers, and numberOfAlarmPositives/numberOfResetPositives to count how often alarms have fired or been reset — effectively serving as an environmental/physical-security alarm-status feed for a rack or facility. As a self-contained device MIB it has no stated dependency on other standard MIBs, using its own IP-management object set. Typical deployment context is telecom cabinets, data-center racks, or equipment rooms where the SNR-ERD-3s unit provides remote environmental/contact-closure monitoring and alarm notification. Network engineers evaluating or troubleshooting this functionality can download the SNR-ERD-3s file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in SNR-ERD-3s. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- NAG SNR-ERD-3s environmental relay/alarm device
Monitoring Examples
An administrator polls monitorAlarmSignal1Contact8 and monitorAlarmSignal2Contact9 to check the state of connected alarm sensors (e.g., door or intrusion contacts), and reviews numberOfAlarmPositives to see how many times an alarm has triggered historically. If monitorAnySensorSignal1contact5 shows an active state while remoteControlContact11 has not been actuated, this points to a real environmental event (rather than an operator-triggered relay) needing on-site investigation; ipForTrap confirms where such alarm traps are being sent.
What Can Be Monitored
- alarm contact sensor states
- generic sensor signal states
- cumulative alarm trigger count
- cumulative reset count
- remote relay control contact state
