SmartCabinet Sensor (CAS)

The SmartCabinet Sensor (CAS) – Professional IT Rack Monitoring for Critical Infrastructures

Comprehensive Server Cabinet Monitoring for Modern Data Centers

The smartCabinet Sensor (CAS) from AKCess Pro® revolutionizes IT rack monitoring in server rooms and data centers through its innovative combination of differential pressure, temperature, and humidity measurement. As an intelligent multi-sensor, it offers a complete solution for rack monitoring in 19-inch IT racks and ensures optimal operating conditions for critical IT infrastructures.

Continuous server room monitoring is achieved by six precise temperature sensors and two humidity sensors, which capture both the front and rear of the IT rack. The integrated differential pressure sensor additionally monitors the pressure conditions between the cold and hot aisles, which is essential for efficient hot aisle/cold aisle configurations.

Technical Specifications and Measurement Accuracy

Temperature Monitoring

The CAS features six temperature sensors with a measuring range of -40°C to +75°C (-40°F to +167°F). The high measurement resolution of 0.1°C (0.2°F) with a maximum deviation of ±0.3°C guarantees precise temperature measurements for critical applications. Additionally, the system automatically calculates three differential temperature values between the front and rear of the rack.

Humidity Measurement

Two high-precision humidity sensors cover the full range from 0 to 100% relative humidity with a resolution of 1% RH. At 25°C, the measurement accuracy is ±2% RH, meeting the strict requirements of professional data centers.

Differential Pressure Monitoring

The integrated differential pressure sensor measures pressure differences of ±125 Pa (±0.5 inH2O / ±1.25 mbar) with a resolution of 0.01 Pa. This precise monitoring is essential for functional control of cold aisle/hot aisle containment and ensures optimal airflow in the server cabinet.

Application Areas and Typical Use Cases

Data Center and Server Room Monitoring

In large data centers, the CAS enables the detection of hotspots and the continuous monitoring of cooling performance. Thermal mapping of the IT rack helps optimize energy efficiency and prevent costly failures.

Hot Aisle / Cold Aisle Monitoring

For modern cold aisle/hot aisle containment, differential pressure measurement is critical. The CAS continuously monitors whether the required overpressure in the cold aisle is maintained to prevent mixing of warm and cold air.

Critical IT Infrastructure Monitoring

Mission-critical servers and network components require constant monitoring of their environmental conditions. The CAS provides 24/7 monitoring with immediate alarm notification when threshold values are exceeded.

SNMP Integration and Network Management

The smartCabinet Sensor seamlessly integrates into existing DCIM (Data Center Infrastructure Management) solutions and network management systems via the proven SNMP protocol. This integration enables:

• Central monitoring of distributed data centers
• Automated alarm and escalation
• Historical data analysis and trend monitoring
• Integration into existing IT service management processes

Direct SNMPget commands allow flexible querying of individual measured values, which is particularly relevant for custom monitoring solutions and specialized monitoring scenarios.

Compatibility and System Integration

SensorProbe+ Platform

The CAS is exclusively compatible with the sensorProbe+ family, including:

• sensorProbe2+ (SP2+): For small to medium-sized installations
• sensorProbeX+ (SPX+): For advanced monitoring requirements

Installation Flexibility

With dimensions of just 75 x 55 x 27 mm and various mounting options (desktop, wall mount, DIN rail, magnetic), the CAS adapts flexibly to different rack configurations. The maximum cable length of 18 meters via standard CAT5/6 cabling allows flexible sensor placement.

Advanced Features and Accessories

AKCPro Server Rack Map View

The dedicated rack map visualization on the AKCPro Server provides a graphical representation of the server cabinet with:

• Real-time temperature distribution
• Airflow visualization
• Differential pressure display
• Alarm status indication

Alarm and Notification

The system offers comprehensive alarm options:

• Email notifications upon threshold exceedance
• SMS alerts via GSM modem or web-to-SMS server
• SNMP traps for network management systems
• Visual and acoustic alarms on site

The data logger function stores all measured values for historical analysis and compliance reports, which is especially important for regulated industries.

Reliability and Operating Environment

Designed with highly integrated SMD technology for long-term reliability, the CAS operates in an extended temperature range of -35°C to +80°C at 20–80% relative humidity (non-condensing). The low power consumption of typically 250 mW makes it ideal for energy-efficient data centers.

Indispensable for Professional IT Rack Monitoring

The smartCabinet Sensor (CAS) represents the next generation of server cabinet monitoring. By combining temperature, humidity, and differential pressure measurement in a compact device, it offers a cost-effective and highly precise solution for modern data centers.

Seamless integration into existing IT infrastructures via SNMP, combined with flexible alarm options and robust construction, makes the CAS the first choice for companies that want to reliably monitor their critical IT infrastructure.
