Vertiv SN-T Single Modular Temperature Sensor
The Vertiv SN-T is a single-channel modular temperature sensor engineered for direct integration with Vertiv Unity and RPC2 environmental monitoring platforms. If you're deploying rack-level or room-level thermal monitoring in a data center, server room, or telecom enclosure, the SN-T slots into the broader Vertiv environmental monitoring lineup as the foundational temperature node — bus-powered through its communications cable, no separate power supply or wiring run required. The SN-T (often searched as SN T) is the component you reach for when you need discrete, addable temperature visibility without overbuilding your sensor infrastructure.
Overview
Thermal monitoring is not optional in any environment running active compute or power conversion equipment. Undetected heat buildup is a leading cause of unplanned downtime, and a single temperature excursion can cascade into hardware failure, voided warranties, or data loss. The SN-T addresses this at the sensor layer: a compact modular unit measuring 41 mm, mountable via the supplied bracket or cable tie, capable of operating in environments ranging from 41°F to 131°F (5°C to 55°C). It draws power through the communications cable itself, which keeps installation straightforward and eliminates the need to route a separate power drop to each sensor location. For environments building out environmental monitoring infrastructure, the modular design means you can add temperature nodes incrementally as your footprint grows.
Key Features
- Bus-Powered via Communications Cable: The SN-T draws all operating power through the same cable that carries its data signal. No separate 12V or 5V power tap, no additional wiring. On a dense sensor deployment — say, 8–12 nodes across a row of racks — this materially reduces installation time and eliminates a category of failure point.
- 41°F to 131°F Operating Range: This covers the full envelope of conditioned data center spaces (typically 65–80°F per ASHRAE A1/A2 guidelines) through warmer telecom closets and industrial edge environments that may run hotter. It won't serve outdoor ambient monitoring in cold climates, but for any indoor active-equipment space, the range is sufficient.
- Supplied Mounting Bracket or Cable Tie: Two mounting methods ship with the unit. The bracket suits hard surfaces where you want a fixed, repeatable position (cold aisle intake, top-of-rack, under a raised floor tile). The cable tie option works in tighter or less structured spaces where drilling isn't an option. Both keep the sensor body stable — sensor placement stability matters for trend consistency in your monitoring platform.
- Single Modular Temperature Channel: The SN-T measures temperature only — no humidity, no airflow. This is deliberate. For deployments where you only need thermal data and want to keep per-point cost down, a single-function sensor is the right architecture. If you need humidity alongside temperature, Vertiv offers companion sensors in the same modular family.
- Direct Unity and RPC2 Integration: The SN-T is purpose-built for Vertiv's Unity and RPC2 monitoring platforms. Integration is not SNMP-only discovery — it's direct, meaning the platform natively understands the sensor's output without requiring custom MIB imports or third-party middleware. For shops already running Unity or RPC2 as their network management layer, this matters: sensor data surfaces in the native UI without extra configuration work.
- 41 mm Compact Form Factor: At 41 mm, the SN-T fits in constrained spaces — inside a rack enclosure, cable tray, or beneath a floor tile — without requiring clearance accommodations. Compact physical footprint also means lower visual and physical profile in customer-facing or aesthetics-sensitive spaces.
- Modular Architecture for Scalable Monitoring: The SN-T is designed as one node in a larger modular sensor ecosystem. You can start with a single unit and expand without replacing existing infrastructure — a practical advantage in phased build-outs or facilities where monitoring scope expands as the equipment footprint does.
Integration & Compatibility
The SN-T integrates directly with Vertiv Unity and RPC2 environmental monitoring platforms. These are the two primary Vertiv monitoring heads used in enterprise and telecom deployments. If your monitoring infrastructure runs on a different platform — say, a third-party DCIM or a non-Vertiv SNMP-based system — verify compatibility before ordering. The SN-T is designed for the Vertiv ecosystem, and direct integration claims apply specifically to Unity and RPC2. For facilities using Vertiv power distribution and monitoring together, the SN-T adds thermal visibility within the same management interface already in use for power events.
Frequently Asked Questions
Q: Does the SN-T require a separate power supply?
A: No. The SN-T draws power through its communications cable, so no separate power supply or additional wiring run is needed at the sensor location.
Q: What monitoring platforms is the SN-T compatible with?
A: The SN-T is designed for direct integration with Vertiv Unity and RPC2 environmental monitoring platforms. Compatibility with third-party or non-Vertiv systems is not specified in available evidence — verify with your platform vendor before deploying outside the Vertiv ecosystem.
Q: What is the operating temperature range of the SN-T?
A: The SN-T operates in environments from 41°F to 131°F (5°C to 55°C), covering the full range of typical conditioned data center and telecom closet environments.
Q: Does the SN-T measure humidity as well as temperature?
A: No. The SN-T is a single-channel temperature-only sensor. For combined temperature and humidity monitoring, Vertiv offers additional modular sensors in the same family.
Q: How is the SN-T mounted?
A: The SN-T ships with a bracket for hard-surface mounting and a cable tie option for flexible or constrained spaces. No special tools or hardware beyond the supplied accessories are required.
Q: Can I add multiple SN-T sensors to a single Unity or RPC2 system?
A: Yes. The modular design is intended for multi-node deployments. You can add temperature sensors incrementally as your monitoring needs expand, without replacing existing infrastructure.
The SN-T is a bus-powered single modular temperature sensor — and that bus-powered aspect is the detail that shapes how I'd deploy it. In a 10-sensor row monitoring build, pulling the communications cable to each SN-T point versus running both data and power to each node is a real installation difference. Vertiv built this correctly for the Unity and RPC2 ecosystem.
Technical Highlights:
- 41°F–131°F Operating Range: Spans the full envelope of active IT spaces — from a tightly conditioned 68°F raised-floor data hall to a 120°F industrial edge closet. Know your environment before deploying; this sensor won't survive an outdoor or cold-storage placement.
- Bus-Powered Communications Cable: Eliminates the per-sensor power tap. On a dense deployment this is not a minor convenience — it cuts materials and labor at every sensor location and removes a discrete failure mode (power connector loosening over time).
- 41 mm Compact Body: Fits inside rack enclosures, under tiles, or in cable trays where a larger sensor body would require clearance accommodations. Placement flexibility directly affects how accurately you can position the sensor at the actual thermal measurement point.
Deployment Considerations:
- The SN-T integrates directly with Unity and RPC2. If your facility runs a non-Vertiv monitoring head, this sensor is not a plug-in SNMP device — confirm your platform supports the Vertiv modular sensor bus before purchasing.
- Temperature only: if your monitoring spec requires relative humidity at the same point, the SN-T does not satisfy that requirement. You will need a companion humidity sensor or a combined unit from the same Vertiv modular family.
The SN-T is the right pick for a Vertiv Unity or RPC2 shop that's building out per-rack or per-zone thermal monitoring incrementally — particularly in phased data center builds where you're adding sensor coverage row by row rather than deploying a full sensor grid on day one.
