APC by Schneider Electric NBWL0455A Room Environment Monitor

Overview

The NBWL0455A is APC by Schneider Electric's NetBotz Room Monitor 455 — an IP-networked environmental monitoring appliance built for data centers, server rooms, telecom closets, and any infrastructure space where temperature, humidity, and physical security conditions must be tracked continuously. Unlike single-sensor dongles or basic threshold alarms, the 455 functions as a local intelligence hub: it aggregates readings from up to 16 universal sensors, two sensor pods, and four IP cameras simultaneously, feeding that data upstream to NetBotz software or SNMP management systems for centralized alerting and logging.

The unit ships without a PoE injector (hence the NBWL0455A SKU) — plan your power delivery accordingly during rack or wall placement. Network connectivity is via a standard RJ-45 10/100 Base-T port, compatible with any managed or unmanaged switch port in your environment.

Key Features

• 16 Universal Sensor Inputs: Sixteen discrete sensor ports let you cover temperature, humidity, airflow, leak detection, door contacts, and dry-contact triggers across a full row of racks or an entire room — all from one appliance. Fewer appliances per floor means fewer management IPs, fewer firmware update cycles, and a cleaner monitoring topology.
• 2 Sensor Pod Expansion Slots: Sensor pods extend coverage to remote corners of large rooms or adjacent spaces without running a separate network drop. Two pod slots on the NBWL0455A give you flexible reach without stacking additional base units.
• 4-Camera Integration: The appliance manages up to four IP cameras simultaneously, linking physical security video directly to environmental event timelines. When a door-contact alarm fires, the correlated camera clip is already in the same event record — no manual cross-referencing across separate systems required. Pair with IP cameras supported by the NetBotz platform for an integrated monitoring view.
• 0–45 °C Operating Range: The monitor itself tolerates ambient temperatures from 0 to 45 °C, meaning it can stay mounted in warm intermediate distribution frames (IDFs) or mechanical rooms where ambient frequently climbs above typical office baseline — without requiring its own dedicated cooling enclosure.
• 0–95% Operating Humidity (Non-Condensing): A full 0–95% relative humidity operating window means the unit stays functional across the widest practical indoor range. This matters in older facilities with uneven HVAC control where humidity spikes are common.
• RJ-45 10/100 Base-T Networking: Standard 10/100 Ethernet keeps the NBWL0455A compatible with any existing network infrastructure — no special SFP modules, no fiber runs required for the appliance itself. Fits naturally into an existing network switch port without consuming high-speed uplink bandwidth.
• Compact Form Factor: At 170 mm wide × 210 mm tall × 95 mm deep and just 0.65 kg, the 455 mounts in tight spaces — inside a rack, on a wall bracket, or on a shelf — without displacing adjacent gear. The low weight simplifies single-person installation.
• 2-Year Manufacturer Warranty: APC backs the NBWL0455A with a 2-year repair-or-replace warranty, reducing the total cost of ownership in long-lifecycle data center deployments where hardware sits in service for many years.

Integration and Compatibility

The NetBotz Room Monitor 455 is designed to integrate with APC's NetBotz software platform and is manageable via SNMP, making it compatible with most enterprise network management systems (NMS) that support SNMP traps and polling. The four-camera input is intended for NetBotz-compatible IP cameras; confirm camera model compatibility with APC's current compatibility matrix before procurement. Universal sensor ports accept APC NetBotz sensor accessories — temperature probes, humidity sensors, airflow sensors, door switches, and dry-contact inputs are the common pairings. For environmental monitoring deployments requiring broader sensor density, multiple 455 units can be distributed across a facility and managed centrally.

The NBWL0455A variant ships without the PoE injector. If your switch does not provide PoE on the port assigned to this device, source the appropriate injector separately. Review your PoE switch port budget and confirm the injector wattage requirement before finalizing the installation plan.

Frequently Asked Questions

Q: What is the difference between the NBWL0455A and the version with a PoE injector?

A: The NBWL0455A ships without a PoE injector. The variant that includes the injector in the box carries a different APC part number. If your network switch does not supply PoE on the assigned port, you will need to source a compatible injector separately for the NBWL0455A.

Q: How many sensors can the NBWL0455A support in total?

A: The NBWL0455A supports up to 16 universal sensors directly plus up to 2 sensor pods, each of which adds further sensor capacity. Up to 4 IP cameras can also be integrated simultaneously.

Q: What is the operating temperature range of the NBWL0455A?

A: The unit operates from 0 °C to 45 °C (32 °F to 113 °F), making it suitable for warm IDF closets and mechanical rooms where ambient temperatures can exceed typical office conditions.

Q: What network connection does the NBWL0455A use?

A: The NBWL0455A connects via a standard RJ-45 10/100 Base-T Ethernet port. No fiber or special uplink hardware is required for the appliance itself.

Q: What warranty does the NBWL0455A carry?

A: APC covers the NBWL0455A with a 2-year repair-or-replace manufacturer warranty.

Q: Can the NBWL0455A be managed via SNMP?

A: The NetBotz platform, which the NBWL0455A is part of, supports SNMP-based management and alerting, making it compatible with enterprise NMS environments that use SNMP traps and polling. Confirm specific MIB and integration details with APC's current documentation.

Karl Wilson

When I spec the NBWL0455A for a data center or server room deployment, the 16-universal-sensor capacity is the number I anchor on first — that's enough discrete sensor inputs to instrument temperature and humidity at every hot-aisle/cold-aisle boundary in a mid-size row without stacking additional base units. Combined with two sensor pod slots and four camera inputs, this appliance covers the full environment-plus-physical-security picture from a single IP address and management point.

Technical Highlights:

• 16 Universal Sensor Ports: Cover temperature, humidity, airflow, leak detection, and door contacts across an entire room from one appliance — fewer management endpoints, fewer firmware cycles.
• 0–95% Operating Humidity Window: The full non-condensing humidity range keeps the monitor functional even in facilities with aging or uneven HVAC, where humidity spikes to 90%+ during cooling failures are a real risk.
• Compact 0.65 kg Chassis: At 170 × 210 × 95 mm and under 700g, the unit installs on a standard wall bracket or shelf inside a rack without displacing adjacent equipment — a practical advantage in dense IDF closets with no spare 1U.

Deployment Considerations:

• The NBWL0455A ships without a PoE injector — verify your switch port supplies PoE before mounting, or budget for a separate injector. Discovering this gap after the unit is already cable-managed in a remote IDF is an avoidable delay.
• Camera integration is limited to four inputs; if your room requires more than four camera feeds tied to environmental events, you will need additional appliances or a different tier in the NetBotz lineup.

This unit is the right fit for mid-size data center rows, colocation cage environments, and telecom rooms where a single appliance needs to handle both environmental sensing across 16 points and correlated physical security video — without requiring a dedicated server to run the monitoring stack.
