Vertiv IS-UNITY-SNMP IntelliSlot SNMP Network Communications Card
Overview
The Vertiv IS-UNITY-SNMP is an IntelliSlot communications card that brings SNMP network monitoring capability to compatible Liebert UPS and power conditioning equipment. If your data center or edge infrastructure team needs to fold UPS status into a building management system (BMS), data center infrastructure management (DCIM) platform, or enterprise NMS, this card is the insertion point — it slots directly into the IntelliSlot bay of the host unit and exposes the UPS over the network without requiring a separate monitoring appliance. It also enables enrollment in Vertiv™ LIFE Services, the manufacturer's remote monitoring and analytics program, making it relevant not just for in-house NMS teams but for managed service providers running remote NOCs.
The IS-UNITY-SNMP (often searched as IS UNITY SNMP) addresses a common gap in edge and distributed UPS deployments: the UPS is physically in the rack, but there is no clean way to pull alarm states, runtime estimates, or load data into the monitoring fabric without either buying a separate network management card or relying on legacy serial connections. This card closes that gap by adding standards-based SNMP communication directly to the host device.
Key Features
- SNMP Integration for BMS and DCIM Platforms: SNMP support means your existing NMS — whether that is SolarWinds, PRTG, Nagios, or a proprietary DCIM tool — can poll the UPS directly for status, load percentage, battery health, and alarm conditions without vendor-specific middleware. If your operations team already manages hundreds of network nodes over SNMP, this card makes the UPS a first-class citizen in that same monitoring view.
- Vertiv LIFE Services Enrollment: The IS-UNITY-SNMP enables connection to Vertiv's LIFE Services remote monitoring platform. For organizations that prefer to offload UPS health monitoring to the manufacturer's support infrastructure — or for MSPs with service contracts — this is the path to proactive fault notification and remote diagnostics without deploying an on-premises monitoring server.
- IntelliSlot Form Factor — Tool-Free Installation: The card installs into the host unit's IntelliSlot bay, which is a dedicated expansion interface on compatible Liebert equipment. No cable adapters, no external hardware. Swap in the card, configure the network settings, and the UPS is on the network. For multi-site deployments where technician time is expensive, this matters.
- Ecosystem Expandable with Sensor Probes: The IntelliSlot ecosystem supports a range of environmental sensor probes that pair with this card: the SN-T single modular temperature probe, the SN-TH temperature and humidity rack monitoring sensor, the SN-2D two-door switch monitor with two inputs, the SN-3C three dry contact input monitor, and the SN-L20 leak detection sensor. If your deployment needs to go beyond UPS status to cover rack temperature, humidity, door intrusion, or water leak detection, those sensors extend the IS-UNITY-SNMP's monitoring footprint without adding another management system.
- Dry Contact and Door Monitoring via Companion Probes: The SN-2D and SN-3C sensor options provide contact closure and dry contact input monitoring respectively — useful in edge sites where you need to track door open/close events or monitor alarm relay states from third-party equipment alongside UPS health. Aggregating both in one SNMP-visible management card simplifies the monitoring architecture for distributed sites.
- Modbus/RTU and BACnet/MSTP via USB485I Adapter: For facilities that run BACnet (common in building automation) or Modbus (common in industrial environments), the USB485I adapter extends protocol coverage to RS-485-based networks. If your site is a mixed BMS environment where some systems speak SNMP and others speak BACnet, the combination of the IS-UNITY-SNMP and the USB485I adapter covers both without requiring a separate protocol gateway.
- Contact Closure Relay Monitoring via RELAYCARD-PG: The companion RELAYCARD-PG card provides contact closure for remote alarm monitoring on Edge UPS units. In deployments where the receiving system is a legacy alarm panel that expects dry contacts rather than IP packets, this accessory bridges the gap. It operates alongside the IntelliSlot architecture rather than replacing it.
Integration and Compatibility
The IS-UNITY-SNMP is designed for the Vertiv Liebert IntelliSlot expansion bay, found across the Liebert GXT, EXM, and related UPS families. Before ordering, verify that your specific Liebert UPS model includes an IntelliSlot bay — not all Liebert units support expansion cards, and some support only one card at a time. If the bay is already occupied by a relay card or another communications module, you will need to choose which function takes priority unless the host unit supports multiple slots.
SNMP-capable management cards require a network connection and a correctly configured SNMP community string or SNMPv3 credential set. Plan for this during commissioning — if your NMS uses SNMPv3 for security policy reasons, confirm that the IS-UNITY-SNMP firmware version in use supports the authentication and privacy protocols your NMS requires.
For broader Liebert monitoring options, explore the full Vertiv power and infrastructure product line or browse the power distribution and UPS category for compatible host units. If your project also involves environmental monitoring, the environmental sensor accessories for rack temperature and humidity pair directly with this card. For network infrastructure planning alongside your UPS deployment, the network switches category provides PoE and managed switching options for the same rack environment. Teams evaluating UPS selection can also reference the UPS selection guide for capacity planning context.
Frequently Asked Questions
Q: What UPS models are compatible with the IS-UNITY-SNMP?
A: The IS-UNITY-SNMP installs into the IntelliSlot expansion bay found on compatible Vertiv Liebert UPS units, including units in the Liebert GXT and EXM families. Verify your specific model has an available IntelliSlot bay before ordering — not all Liebert UPS units include this expansion interface.
Q: Does the IS-UNITY-SNMP support SNMPv3?
A: The card supports SNMP for BMS and DCIM integration. For specific SNMPv3 authentication and privacy protocol support, consult the current Vertiv firmware release notes for your host unit, as supported SNMP versions depend on firmware revision.
Q: Can the IS-UNITY-SNMP connect to Vertiv LIFE Services?
A: Yes. The IS-UNITY-SNMP explicitly supports enrollment in Vertiv LIFE Services, the manufacturer's remote monitoring and analytics platform, in addition to local SNMP-based NMS integration.
Q: Can environmental sensors like temperature or leak detectors be added to the IS-UNITY-SNMP?
A: Yes. The IntelliSlot ecosystem supports a range of sensor probes that pair with this card, including the SN-T (temperature), SN-TH (temperature and humidity), SN-L20 (leak detection), SN-2D (two-door switch monitor), and SN-3C (three dry contact input monitor). These expand monitoring coverage beyond UPS status to rack environment conditions.
Q: Does the IS-UNITY-SNMP support BACnet or Modbus for building automation integration?
A: BACnet/MSTP and Modbus/RTU protocol support is available through the USB485I adapter (RS-485 to USB), which extends the IntelliSlot platform to facilities running building automation systems on RS-485 networks.
Q: Can only one IntelliSlot card be installed at a time?
A: This depends on the host Liebert UPS model. Some units support a single IntelliSlot card; others support multiple. If your unit has only one bay and it is occupied by a relay card or another module, you will need to select between functions or verify whether a multi-slot chassis is available for your UPS family.
The IS-UNITY-SNMP is the card I reach for when a client has Liebert UPS units on the floor that are invisible to their NMS — no polling, no trap receivers, no runtime data in the DCIM dashboard. Dropping this into the IntelliSlot bay and configuring an SNMP community string is typically a sub-30-minute commissioning task that converts a monitoring blind spot into a fully visible network node. The LIFE Services integration is a genuine bonus for facilities teams that want manufacturer-side remote diagnostics without standing up their own monitoring infrastructure.
Technical Highlights:
- SNMP Protocol Support: Standards-based SNMP means the UPS integrates into any NMS that can poll network devices — no proprietary agent software required on the management server, and no vendor lock-in on the monitoring platform.
- Vertiv LIFE Services: The card's LIFE Services connectivity enables manufacturer-side remote monitoring, which matters for sites running lean IT staff where proactive fault detection from the vendor is more practical than building an internal NOC capability.
- Sensor Probe Ecosystem: The IntelliSlot architecture supports the SN-TH temperature/humidity sensor, SN-L20 leak detection, SN-2D door monitoring, and SN-3C dry contact inputs — meaning one management card can aggregate UPS status and physical environment data into a single SNMP data stream.
Deployment Considerations:
- Confirm the IntelliSlot bay is available and unoccupied on your specific Liebert unit before the card ships to site — some UPS models ship with a relay card already installed, and there is often only one bay available.
- If your NMS enforces SNMPv3 with AES privacy and SHA authentication, verify the IS-UNITY-SNMP firmware version supports those specific cipher configurations before commissioning — SNMP version support can vary by firmware release.
The IS-UNITY-SNMP is the right call for edge data center buildouts and distributed branch deployments where Liebert UPS units need to participate in a centralized SNMP monitoring fabric without adding a separate network management appliance to every rack.
