Connecting devices at the edge of a network is rarely as straightforward as installing a switch in a climate-controlled equipment room. Roadside cabinets, camera poles, utility enclosures, transportation systems, and remote industrial sites introduce a different set of challenges: extreme temperatures, limited space, inconsistent power, long transmission distances, and restricted access for maintenance.
In these environments, the network switch is not simply another piece of hardware. It's often the point where cameras, intercoms, wireless access points, sensors, and other critical edge devices connect to the wider system. A failure at that point can interrupt communications, eliminate video coverage, disable monitoring, or require an expensive service visit.
The new AMG350 Series Industrial Unmanaged Ethernet Switches are designed to address these practical deployment problems without adding unnecessary configuration or management complexity.
Standard Network Equipment Is Not Designed for Extreme Locations
Commercial network switches generally perform well in offices, data rooms, and other controlled environments. They are far less suitable inside an outdoor enclosure exposed to summer heat, winter cold, vibration, dust, and fluctuating electrical conditions.
The AMG350 Series is designed for industrial operating temperatures from -40°C to +75°C. Its thermally efficient housing is intended to maintain reliable operation under full load, making the series appropriate for roadside cabinets, camera poles, utility enclosures, transportation infrastructure, and industrial sites where environmental control may be limited or unavailable.
This wider operating range helps system designers avoid a common mistake: selecting a switch based only on port count and bandwidth while overlooking the environment in which it must operate.
Many edge installations have little room for additional equipment. Camera poles, traffic cabinets, small control panels, and retrofit enclosures may already contain power supplies, surge protection, fiber termination equipment, and other components.
The AMG350 Series uses a compact housing that can be mounted on a DIN rail or directly to a wall. The AMG350-5G-2S model, for example, measures approximately 1.85 inches wide, 4.17 inches deep, and 5.67 inches high. This narrow form factor allows the switch to fit into confined locations without requiring a larger cabinet or a major enclosure redesign.
DIN rail mounting also simplifies installation and replacement. Instead of fabricating a custom shelf or mounting plate, technicians can secure the switch using the same mounting approach commonly used for industrial power supplies, relays, and control devices.
Copper Ethernet is useful for connecting nearby devices, but industrial and transportation networks frequently require communication between widely separated locations. A remote camera, intersection cabinet, perimeter device, or industrial process may be hundreds of feet—or many miles—from the nearest network aggregation point.
The AMG350 Series combines five RJ45 Ethernet ports with two dedicated Gigabit SFP fiber ports. Depending on the selected SFP modules, the switches can support single-mode or multimode fiber, single-fiber or dual-fiber configurations, and transmission distances of up to 120 kilometers.
This provides a practical way to connect several local edge devices while using fiber for the long-distance uplink or network backbone. It also gives designers flexibility to match the fiber interface to the existing infrastructure rather than being locked into one fiber type or transmission distance.
SFP modules and power supplies are selected separately, which should be considered during system design and procurement.
The power requirements of edge devices continue to increase. Fixed cameras may require relatively little power, while PTZ cameras, illuminators, wireless radios, intercoms, heaters, and other devices may require substantially more.
The AMG350 Series includes models with PoE options ranging from 15 watts through 90 watts. This allows the switch to support a variety of connected devices without requiring a separate local power supply for every endpoint. The available power levels include 15W PoE, 30W PoE+, 60W PoE++, and 90W high-power PoE.
For sites where only low-voltage power is available, AMG also offers LV models with an integrated 12–56VDC booster circuit. The circuit produces a regulated 54VDC output for PoE operation, helping solve the problem of powering PoE devices from an existing low-voltage source.
This can be particularly useful in transportation, solar-powered, mobile, and remote infrastructure applications where conventional AC power is unavailable or difficult to install.
Managed switches provide valuable network controls, diagnostics, segmentation, and redundancy features. However, not every edge location requires that level of management. In a straightforward point-of-connection application, additional configuration can increase deployment time and create another set of settings that must be documented and maintained.
The AMG350 Series is unmanaged and designed for plug-and-play operation. Auto-negotiation automatically determines the appropriate connection speed, allowing technicians to connect devices without loading software or configuring the switch.
Unmanaged operation does not mean the switch ignores reliability. The series includes dual redundant power inputs and a fault relay output. Two power inputs can help maintain operation if one source is lost, while the relay can provide a rapid indication of a power fault to an external monitoring or alarm system.
For remote sites, this combination addresses two different operational problems: reducing the amount of configuration required during installation and improving the ability to detect a power-related failure after deployment.
When evaluating the series, system designers should consider:
By evaluating these requirements before selecting a model, integrators can avoid over-specifying a simple edge connection or underspecifying a switch that must operate in a demanding environment.
Industrial edge networks often fail for reasons that have little to do with raw bandwidth. Equipment may overheat, lose power, exceed the available PoE budget, outgrow an enclosure, or require a fiber connection that was not considered during the original design.
The AMG350 Series addresses these issues through a compact industrial form factor, extended-temperature operation, flexible fiber connectivity, PoE options up to 90 watts, low-voltage power conversion, redundant power inputs, and plug-and-play deployment.
The result is not simply another Ethernet switch. It is a practical option for solving the environmental, power, distance, and installation challenges that frequently determine whether an edge network remains dependable after the installation team leaves the site.
The AMG350 Series is a family of compact, industrial-grade unmanaged Ethernet switches designed for edge-network applications where dependable copper, fiber and optional PoE connectivity are needed without managed-switch configuration. AMG identifies transportation systems, roadside infrastructure, security networks, camera deployments and industrial automation among the intended applications.
No. The AMG350 Series is unmanaged and designed for plug-and-play deployment. It does not require software configuration and includes auto-negotiation to determine the appropriate Ethernet connection speed. Projects requiring VLANs, traffic prioritization, detailed network monitoring, managed redundancy or other advanced network controls should use an appropriate managed-switch architecture instead.
The new seven-port AMG350 models combine five RJ45 Ethernet ports with two dedicated Gigabit SFP ports. The series includes 100 Mbps and Gigabit Ethernet switching options, while the SFP interfaces provide Gigabit backbone connectivity.
No. The series includes both non-PoE and PoE models. Depending on the model and power supply selected, available PoE configurations include 15W PoE, 30W PoE+, 60W PoE++ and 90W high-power PoE. The specific AMG350-5G-2S model referenced on AMG’s product page is a non-PoE model, so the complete model number and PoE requirements must be confirmed during system design.
Depending on the power requirements of the device and the AMG350 model selected, PoE versions can support equipment such as IP cameras, PTZ cameras, wireless access points, intercoms, sensors and other network-connected edge devices. The system designer should verify both the per-port requirement and the total switch PoE budget before specifying a model.
Selected LV models include an integrated 12–56VDC booster circuit that provides a regulated 54VDC output for PoE operation. This can help support PoE devices at sites where only low-voltage DC power is available.
The SFP ports can support single-mode or multimode fiber as well as single-fiber or dual-fiber configurations. The appropriate SFP must be selected based on the installed fiber, connector requirements and transmission distance.
AMG lists fiber transmission distances of up to 120 kilometers, depending on the SFP module and fiber infrastructure selected for the application. The maximum distance is not provided by the switch alone; it depends on the complete optical link design.
No. SFP modules and power supplies must be ordered separately. This allows each installation to use the appropriate fiber interface and power supply, but those components must be included in the project bill of materials.
The AMG350 Series is designed to operate from -40°C to +75°C. This extended range makes it suitable for roadside cabinets, utility enclosures, camera poles and other locations where commercial-grade networking equipment may not tolerate the environmental conditions.
Yes. The switches use a compact industrial housing and support DIN rail or wall mounting. The AMG350-5G-2S measures approximately 1.85 inches wide, 4.17 inches deep and 5.67 inches high, although dimensions should be confirmed for the exact model being specified.
The series includes dual redundant power inputs and a fault-relay output. The redundant inputs can support a more resilient power design, while the relay can communicate a power fault to an external alarm or monitoring system. The relay does not provide the same visibility as a fully managed network switch, but it can provide useful fault notification at remote sites.
No. It is best suited to applications where straightforward, reliable edge connectivity is the primary requirement. A managed switch should be considered when the design requires VLANs, detailed network monitoring, quality-of-service controls, advanced cybersecurity functions, managed redundancy protocols or remote port configuration. AMG has various managed switch options for applications with that requirement.
System designers should confirm the number and speed of copper connections, fiber type, fiber distance, SFP requirements, per-device PoE demand, total PoE budget, available input voltage, environmental temperature, enclosure space, redundant-power requirements and the need for managed network functionality. Evaluating these requirements helps prevent both over-specifying a simple connection and under-specifying a demanding field application.
