Vertiv IS-UNITY-DP IntelliSlot Unity Management Card
Overview
The Vertiv IS-UNITY-DP is an IntelliSlot management module designed to bring enterprise-grade network management, multi-protocol building automation integration, and environmental monitoring to compatible Liebert UPS and power distribution equipment. If you're running a data center, telecom closet, or critical facility where power infrastructure needs to talk to your BMS, DCIM, or NMS — this is the card that closes that gap. The IS-UNITY-DP drops into a Liebert IntelliSlot bay and immediately adds SNMP, BACnet, Modbus, and web-based management without requiring a dedicated external gateway appliance.
For engineers integrating Vertiv Liebert power equipment into converged infrastructure management platforms, the IS-UNITY-DP (often searched as IS UNITY DP) eliminates the need for serial-to-network converters or third-party polling relays — the card handles all protocol translation natively on-board.
Key Features
- SNMP v1, v2c, and v3: All three SNMP generations are supported simultaneously, so you can poll legacy NMS platforms and modern SNMPv3-secured management systems from the same card. SNMPv3 in particular matters if your security team requires authenticated, encrypted trap delivery — you won't need to run a separate proxy.
- BACnet IP and MSTP — BTL Certified: Both BACnet transport modes are BTL (BACnet Testing Laboratories) certified, which is the interoperability credential building automation integrators require before they'll wire a device into a BMS. This isn't a software-claim BACnet implementation — it's third-party certified, so it belongs in a real BAS project spec without asterisks.
- Modbus TCP and RTU: Dual Modbus support means the IS-UNITY-DP can feed power and environmental data directly into industrial SCADA systems or energy management platforms that speak Modbus RTU over RS-485 — the same serial bus the card uses for its RS-485 networking interface (9600–115200 BAUD). No separate RTU-to-TCP gateway needed.
- 10/100 Mbps Ethernet + RS-485: Two physical network paths — standard RJ-45 Ethernet for IP-based protocols (SNMP, BACnet/IP, Modbus TCP, web UI) and an RS-485 serial interface for RS-485 Modbus RTU and BACnet MSTP segments. This dual-path design lets you wire into both IP and legacy serial BMS loops from a single card slot.
- Web UI via HTTP and HTTPS with loadable certificates: The browser-based management interface supports HTTPS with customer-supplied certificates, so you can issue a cert from your internal PKI and eliminate the browser trust warnings that plague self-signed setups. HTTP is available for non-secure networks or initial configuration.
- Environmental sensor inputs — Temp, Humidity, Leak, Door, Contact Closure: The IS-UNITY-DP can accept Liebert SN environmental sensors directly, making it a single integration point for both power data and physical environment monitoring. Temperature, humidity, leak detection, door state, and dry-contact closure inputs all report through the same SNMP/BACnet/Modbus feeds — useful when your NMS needs correlated power and environment events in a single data stream.
- Email and SMS notifications (SMTP/SMS): Alarm delivery via email and text message doesn't require a separate notification gateway. Configure SMTP relay details and SMS targets on the card itself, and operators get direct alerts on UPS events, sensor threshold breaches, or communication loss — without depending on an external alerting middleware stack.
- YDN23 protocol support: YDN23 is a Chinese telecom power management standard required in certain carrier and data center environments. Presence here indicates the IS-UNITY-DP is deployable in international telecom facility contexts where YDN23 compliance is a procurement requirement.
- LIFE Services compatible: Compatibility with Vertiv LIFE Services enables predictive analytics and remote monitoring through Vertiv's service platform — relevant if your maintenance contract includes proactive monitoring or if you're evaluating remote managed services for critical power infrastructure.
- Linux-based operating environment: The card runs Linux, which means the firmware update and security patch cadence follows an OS-grounded model rather than bare-metal firmware. For security-conscious facilities teams, this also means the attack surface and patching model are well-understood.
Integration and Compatibility
The IS-UNITY-DP is designed for Liebert equipment with an available IntelliSlot expansion bay — confirm your UPS or PDU model has an open IntelliSlot slot before ordering. Inputs are drawn from Liebert SN sensors and the web UI; there is no configuration port on the card itself. The RS-485 interface operates at selectable baud rates from 9600 to 115200, covering the full range of BACnet MSTP and Modbus RTU device populations you're likely to encounter on an existing BMS segment.
For UPS and power management deployments that require BACnet integration, the BTL certification on both BACnet/IP and MSTP modes is the key differentiator — it confirms the implementation meets interoperability requirements that BMS integrators and commissioning engineers check during acceptance testing. Pair with a managed network switch that supports 802.1Q VLANs if your BMS and IT management networks need to stay segmented while sharing the same physical infrastructure.
If your facility uses a DCIM or power management platform, the IS-UNITY-DP's multi-protocol support means you can poll it from the DCIM via SNMP while simultaneously feeding the BMS via BACnet — no need to choose one protocol or deploy parallel gateways. Review your UPS accessories and expansion modules to confirm slot availability and sensor cabling options for your specific Liebert chassis.
Frequently Asked Questions
Q: What network protocols does the IS-UNITY-DP support?
A: The IS-UNITY-DP supports SNMP v1, v2c, and v3; BACnet/IP and BACnet MSTP (both BTL Certified); and Modbus TCP and RTU. It also provides a web management interface via HTTP and HTTPS, and supports email/SMS notifications via SMTP/SMS.
Q: Is the IS-UNITY-DP BACnet BTL Certified?
A: Yes. Both BACnet/IP and BACnet MSTP implementations on the IS-UNITY-DP are BTL (BACnet Testing Laboratories) certified, confirming interoperability compliance for building automation system integration projects.
Q: What environmental sensors can the IS-UNITY-DP monitor?
A: The card supports Liebert SN sensors for temperature, humidity, leak detection, door state, and contact closure inputs. All sensor data is reportable through the card's SNMP, BACnet, and Modbus interfaces.
Q: Does the IS-UNITY-DP support HTTPS with custom certificates?
A: Yes. The web user interface supports both HTTP and HTTPS, and the card accepts loadable certificates — allowing you to install a certificate issued by your internal PKI rather than relying on a self-signed certificate.
Q: What physical network interfaces does the IS-UNITY-DP provide?
A: The card includes a 10/100 Mbps Ethernet port for IP-based protocols and an RS-485 serial interface operating at selectable baud rates from 9600 to 115200 BAUD for Modbus RTU and BACnet MSTP connections.
Q: Does the IS-UNITY-DP have a configuration port?
A: No. The IS-UNITY-DP does not include a dedicated configuration port. Initial setup and ongoing configuration are performed through the web user interface or via Liebert SN sensor inputs.
The IS-UNITY-DP is the card I recommend when a facility's BMS integrator shows up with a BACnet/MSTP requirement and the UPS room is already running Liebert equipment. The BTL certification on both BACnet/IP and MSTP is what actually matters in that conversation — it's the difference between a card that passes commissioning and one that creates a month-long interoperability dispute with the controls contractor.
Technical Highlights:
- BTL-Certified BACnet (IP + MSTP): Both transport modes are independently BTL certified — not just claimed compatible. On projects where the BAS acceptance test requires BTL-listed devices, this clears the gate without a waiver.
- RS-485 at 9600–115200 BAUD: The adjustable baud rate on the RS-485 port matters when you're dropping the IS-UNITY-DP onto an existing MSTP or Modbus RTU segment that was set up years ago at a non-default rate. You're not stuck re-wiring the segment to match a fixed baud.
- SNMP v3 with HTTPS and loadable certificates: SNMPv3 authenticated traps plus a PKI-issued HTTPS cert means the card fits into a hardened network zone without exemptions. These are the two items security teams most commonly flag on network-attached power devices.
Deployment Considerations:
- Confirm an open IntelliSlot bay before ordering — the IS-UNITY-DP installs into the Liebert IntelliSlot expansion slot and there is no standalone enclosure option. Some Liebert models ship with the slot occupied by a basic card that must be removed.
- There is no dedicated configuration port on this card, so initial IP addressing must be done via the web UI — plan for direct Ethernet access to the card during commissioning, or confirm DHCP is available on the management VLAN before the card goes live.
The IS-UNITY-DP is the right pick for critical facility projects where the UPS infrastructure must report into both an IP-based DCIM or NMS and a serial BACnet MSTP building automation system simultaneously — the dual-protocol, dual-physical-interface design handles that split without a gateway in the middle.
