Gigabit SNMP card for secure remote UPS monitoring and shutdown

The UPNETG2 is Uniti Power's Gigabit network management card, an SNMP-based module for remote monitoring and control of UPS systems through a secure web browser interface. Built on an embedded Linux platform, it supports SNMP v1/v3, Modbus TCP, MQTT, HTTPS and a REST API, and works with WinPower G2 and SPS G2 to shut down physical and virtual servers safely during a power outage.

For IT teams, facilities managers and service providers, the UPNETG2 brings UPS status, alarms and battery condition into the wider network-management environment, so problems can be seen and acted on without anyone being at the equipment.

Where the UPNETG2 is used

Typical applications include data centres, IT and server rooms, industrial facilities, remote branch offices and edge computing environments.

Key capabilities

• Web-based management: an embedded HTML5 interface over HTTPS, with no software installation, compatible with Chrome, Edge, Firefox and Safari (latest versions recommended).
• Multi-protocol support: SNMP v1/v3, Modbus TCP, MQTT and HTTPS for integration with network management tools, SCADA and other industrial systems.
• REST API: secure integration with third-party platforms and custom software.
• Management features: UPS and PDU discovery, alarm notifications, outlet control, battery testing, shutdown scheduling, event and data logging.
• Environmental monitoring: with the optional SPYEMP probe, temperature from 0 to 70°C and humidity from 10 to 90%, with alerts when thresholds are exceeded.

Cybersecurity

Secure boot prevents unauthorised firmware running, firmware images are encrypted, and access is controlled by user role, a configurable firewall with port-level management, and TLS/SSL, SNMPv3 and LDAP authentication. Credentials are held in an isolated secure enclave.

Shutdown with WinPower G2 and SPS G2

WinPower G2 gives a browser-based dashboard across UPS systems, with auto discovery, live data, event logging and remote shutdown of connected systems including VMware, ESXi, IPMI, SSH and NetApp. SPS G2 runs on individual Windows, Linux or macOS endpoints for graceful local shutdown, including scripted shutdown sequences.

Compatibility and installation

The UPNETG2 is designed to support all Uniti Power UPS models with a network card slot, including the Symphony range. The G2 card platform is designed for both short and long card slots, and a short-format UPNETG2S is also listed. Confirm the right card for your UPS model with Uniti Power technical support.

The card is hot-swappable, so fitting or removing it has no effect on the UPS output. It connects with a shielded Gigabit Ethernet cable and can be configured over USB before it goes on the network.

Warranty and support

See warranty information for the terms that apply to the UPNETG2. Documentation and software are available from the downloads page.

UPNETG2 network card questions answered

Which protocols does the UPNETG2 support?
The UPNETG2 supports SNMP v1/v3, Modbus TCP, MQTT and HTTPS, plus a REST API and SSH command-line access.

Can the UPNETG2 shut down virtual servers?
Yes. Paired with WinPower G2, the UPNETG2 can initiate controlled shutdown of local and virtual servers, including VMware, ESXi, IPMI, SSH and NetApp systems.

Does the UPNETG2 monitor temperature and humidity?
Yes, with the optional SPYEMP probe, which measures 0-70°C and 10-90% humidity and triggers alerts when readings pass configured thresholds.
