Application Overview

A leading refrigerated logistics provider operates multiple large-scale cold storage warehouses that support the food distribution and pharmaceutical industries. These facilities require continuous network connectivity throughout refrigerated, frozen, and loading dock environments where temperatures can range from standard warehouse conditions down to -40°C in deep-freeze storage areas.

The company’s legacy commercial Ethernet infrastructure was unable to reliably operate within freezer zones, required separate electrical circuits for network devices, and lacked centralized management for mission-critical systems.

To modernize its facilities, the customer initiated a network upgrade to support high-speed communications, centralized network management, and Power over Ethernet (PoE) delivery for hundreds of edge devices located throughout the warehouse.

After evaluating several industrial networking manufacturers, the customer selected Omnitron Systems RuggedNet® Industrial Managed PoE Switches as the foundation for its new warehouse communications infrastructure.

Challenges

The warehouse network supports critical operational systems that must remain online 24 hours a day while operating in one of the harshest commercial environments.

Key challenges included:

• Reliable Ethernet operation in temperatures ranging from ambient warehouse conditions to -40°C freezer environments
• High humidity and condensation created during refrigeration and defrost cycles
• Continuous vibration generated by compressors and material handling equipment
• Long cable distances between control rooms and freezer storage areas
• Limited electrical infrastructure for powering remote network devices
• Centralized management of multiple warehouse network segments
• High network availability to prevent disruptions to warehouse operations
• Future scalability to support warehouse automation and Industrial IoT applications

The upgraded infrastructure needed to support:

• IP security cameras
• Wireless access points for barcode scanners and mobile terminals
• RFID inventory readers
• Environmental monitoring sensors
• Automated Guided Vehicles (AGVs)
• Industrial control systems
• Door access control
• Intercom and emergency communication systems

The customer also required a solution capable of supporting future bandwidth growth, including multi-gigabit and 10Gbps network uplinks.

Omnitron Solution

Omnitron designed a resilient industrial Ethernet architecture utilizing RuggedNet® Industrial Managed PoE Switches strategically installed throughout freezer rooms, refrigerated storage, loading docks, and warehouse operations centers.

A high-speed fiber optic backbone interconnects the industrial switches, providing:

• Gigabit and 10 Gigabit Ethernet connectivity
• High-bandwidth aggregation to the warehouse control center
• Immunity to electromagnetic interference from refrigeration equipment
• Long-distance connectivity between buildings and warehouse zones
• Redundant network paths for maximum uptime

Each RuggedNet Industrial Managed PoE Switch provides IEEE 802.3af/at/bt compliant Power over Ethernet, allowing both power and data to be delivered over a single Ethernet cable.

This significantly reduced installation complexity by eliminating local power supplies for edge devices while improving overall network reliability.

RuggedNet Industrial PoE Switch Connectivity

The Omnitron RuggedNet switches provide centralized connectivity and power for:

IP Security Cameras

Industrial PoE ports power fixed and PTZ security cameras throughout freezer storage, shipping docks, production areas, and exterior facilities. High-resolution video is transported over fiber uplinks to the security operations center.

Wireless Access Points

PoE-powered Wi-Fi access points provide seamless wireless coverage for warehouse personnel using handheld barcode scanners, forklift terminals, tablets, and mobile computers.

RFID Readers

RFID readers located throughout receiving, storage, and shipping operations automatically track inventory movement and update warehouse management systems in real time.

Environmental Monitoring Sensors

Industrial sensors continuously monitor:

• Temperature
• Humidity
• Refrigeration equipment
• Freezer performance
• Alarm conditions

Critical environmental data is transmitted directly to the warehouse control center.

Automated Guided Vehicles (AGVs)

Reliable wireless infrastructure supported by RuggedNet switches enables uninterrupted communications between AGVs and warehouse control software, improving material handling efficiency.

Industrial Control Systems

Programmable Logic Controllers (PLCs), automation controllers, and refrigeration management systems communicate over the industrial Ethernet network to coordinate warehouse operations.

Door Access Control

PoE-powered badge readers, electronic locks, and access control panels secure restricted freezer areas while enabling centralized monitoring.

Intercom and Emergency Communications

Industrial VoIP intercom stations and emergency communication devices receive both power and network connectivity through RuggedNet PoE ports, ensuring reliable operation during emergencies.

Centralized Network Management

The warehouse control center manages the entire industrial Ethernet infrastructure through the advanced management capabilities of the RuggedNet switches.

Network administrators can remotely:

• Monitor switch health and network status
• Configure VLANs and Quality of Service (QoS)
• Manage PoE power allocation
• Restart remote PoE devices
• Monitor bandwidth utilization
• Receive SNMP alerts and event notifications
• Configure network redundancy
• Diagnose network faults remotely
• Update switch firmware
• Monitor connected edge devices

Centralized management significantly reduces maintenance time while improving overall network availability.
