Description: Manages NAG SNR-ERD-4 environmental relay device sensor readings, relay outputs, and alarm thresholds.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is SNR-ERD-4?

SNR-ERD-4 is a vendor MIB from NAG for the SNR-ERD environmental relay device, a rack-mount sensor/relay monitoring unit used in telecom and data-center environments. It exposes readings from multiple analog and digital sensor inputs (voltage sensor and a bank of serial-numbered sensor channels S1-S10), including temperature sensors, along with relay outputs and configurable alarm thresholds. Its core purpose is environmental hardware monitoring: administrators poll voltage and temperature sensor channels to detect out-of-range conditions such as overheating equipment racks or power supply voltage drift, and use relay status to confirm alarm outputs (e.g., door contacts, smoke/water sensors wired to the unit) are functioning as expected. As a self-contained environmental monitoring appliance MIB, it has no significant dependency on other vendor MIBs beyond standard SNMP. It is typically deployed in telecom equipment rooms, data-center racks, or remote cabinets where the SNR-ERD-4 unit provides centralized environmental and relay-based alarm monitoring via SNMP. Engineers can download the SNR-ERD-4 file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SNR-ERD-4. 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.

Monitoring Examples

A facilities engineer would poll temperatureS1 alongside the other serial channels (serialS1 through serialS10) to track ambient or equipment temperature in a rack, and check voltageSensor to confirm DC power feed voltage stays within tolerance. Under the measurements branch, a temperature reading exceeding a configured threshold would indicate a cooling failure in the equipment room requiring immediate attention. Monitoring multiple serial sensor channels together helps correlate a voltage dip with a rising temperature trend, pointing to a broader power or cooling event.
