Introduction to the AMG350-4GAT-1G-P120 and its key features
TheAMG350-4GAT-1G-P120is a compact, industrial-grade 5‑port unmanaged Gigabit PoE switch built for harsh-edge networking and surveillance applications. Designed for reliable operation in challenging environments, this small yet robust switch puts four IEEE 802.3af/at PoE ports and a single Gigabit uplink into a rugged DIN‑rail/wall‑mount enclosure. Key features include a roughly 120 W PoE budget, dual redundant DC power inputs, a wide operating temperature range (−40°C to +75°C), and plug‑and‑play unmanaged operation with auto MDI/MDI‑X and speed/duplex negotiation.
Detailed specifications and benefits
The AMG350-4GAT-1G-P120 is engineered with industrial reliability and simplicity in mind. Below is a breakdown of its main specifications and the practical benefits each brings.
- 4 × 10/100/1000 RJ45 PoE ports (ports 1–4)— Each port supports IEEE 802.3af/at (15 W / 30 W) so modern IP cameras, access points and other mid‑to‑high power devices can be powered directly over Ethernet.
- 1 × 10/100/1000 RJ45 uplink port— A full Gigabit uplink provides a reliable backhaul to an NVR, switch, router or industrial controller.
- Auto MDI/MDI‑X and auto negotiation— Eliminates the need for crossover cables or manual configuration; the switch is truly plug‑and‑play.
- PoE standard and budget— Supports IEEE 802.3af/at, with the P120 variant sized for approximately 120 W total PoE budget (roughly 4 × 30 W). This is sufficient to run four 802.3at devices at full power or a mix of af/at devices depending on total draw.
- Dual redundant DC inputs— Typical 48–56 VDC inputs via a removable terminal block provide redundancy and compatibility with common industrial power supplies and vehicle/transport power systems. Redundant inputs help keep critical systems online during a single supply fault.
- Wide operating temperature— Rated for −40°C to +75°C operation, suitable for outdoor enclosures, transport, factory floors and other temperature‑extreme locations (verify variant and installation requirements).
- Mounting and enclosure— Rugged, thermally efficient industrial housing with DIN‑rail and wall mount options simplifies installation in control cabinets, poles or service rooms.
- Rugged design— Industrial mechanical tolerances and an IP30/IP40‑style enclosure (check variant) reduce the risk of failure from vibration, dust and mechanical stress in real deployments.
- Compliance notes— NDAA/TAA references appear on some partner pages; full CE/UKCA and other compliance details should be confirmed in the official datasheet.
- Manufacturer support— AMG provides lifetime support references on manufacturer pages; always consult the official manual for installation and safety guidance.
- MTBF— Typical MTBF figures are in the order of hundreds of thousands of hours, reflecting industrial component selection and design practices.
Use cases and scenarios where the AMG350-4GAT-1G-P120 excels
This switch is purpose‑built for scenarios where ruggedness, compact size and PoE capability are essential. Typical use cases include:
- Small to medium camera deployments where up to four PoE cameras need power and a dedicated uplink to an NVR or central switch. The 120 W PoE budget allows support for four 802.3at cameras at higher power draw or mixed power requirements depending on model.
- Powering outdoor or indoor Wi‑Fi access points in retail, manufacturing or transportation hubs without adding a separate power feed to each device.
- Vehicle, rail or marine edge networking where a compact DIN‑rail/wall mount switch and wide input voltage tolerance (48–56 VDC) are advantageous. Redundant DC inputs support higher availability in critical systems.
- Feeding PoE sensors, controllers and other IP devices on factory floors, substations or remote monitoring points where environmental extremes demand wider temperature ranges and rugged enclosures.
Comparisons with similar products in the market
When evaluating the AMG350-4GAT-1G-P120, consider how it lines up against other small industrial PoE switches and alternative approaches:
- Unmanaged advantages— Simplicity, lower cost, minimal configuration and quick deployment. AMG350 is ideal when you need reliable PoE delivery without VLANs, SNMP or advanced QoS.
- Managed alternatives— Managed industrial switches offer VLANs, traffic shaping, PoE scheduling and monitoring, and better diagnostics. If you need network segmentation, remote troubleshooting or precise traffic control, a managed unit is preferable—at higher cost and complexity.
- The AMG350’s 4 PoE ports and ~120 W budget are balanced for small clusters of devices. If your deployment needs more endpoints or higher aggregate PoE (eight or more cameras, or multiple high‑power APs), look for 8‑port or 16‑port industrial PoE switches with larger budgets (240 W or higher).
- Some competitors offer higher IP ratings (IP65/IP67) or fully sealed enclosures for direct outdoor pole mounting; AMG350 is designed for cabinet/pole enclosure installations where DIN‑rail mounting and IP30/IP40‑style protection are sufficient.
Customer feedback and reviews
Public, model‑specific customer testimonials for industrial hardware like the AMG350 series are commonly found on distributor pages and in system integrator notes. Common themes reported by installers and integrators for switches of this class include:
- Reliability— Rugged units with redundant power inputs and wide temperature ranges are praised for staying online in factory and transport environments.
- Ease of deployment— Unmanaged switches that are truly plug‑and‑play reduce installation time and troubleshooting complexity for straightforward camera and AP deployments.
- Value— Systems integrators often comment that compact industrial PoE switches offer a strong cost‑to‑function ratio when a modest number of endpoints must be powered in difficult environments.
Note: For specific quoted reviews, datasheets and warranty information, consult the manufacturer pages or authorised distributors. AMG lists lifetime support references and compliance information on official pages and partner sites.
Installation, safety and practical tips
To get the most from the AMG350-4GAT-1G-P120 and to ensure safety and longevity:
- Always isolate power before wiring the removable terminal block and ensure correct polarity and voltage within the specified range (typically 48–56 VDC).
- Calculate the total PoE draw of connected devices and confirm it does not exceed the switch’s ~120 W budget. Prioritise critical devices or use a managed midspan/PSE if per‑port scheduling is needed.
- Provide adequate ventilation and follow manufacturer mounting guidance—thermal dissipation matters in tight cabinets, especially under full PoE load.
- Observe local electrical codes and consult the official datasheet/manual for grounding, surge protection and cable type recommendations.
