Industrial PoE Switch ALLNET ALL-SGI8003P-2.5G — 3 ports 2.5G, PoE

The ALLNET ALL-SGI8003P-2.5G is an industrial Power over Ethernet (PoE) switch that combines three 2.5G Ethernet ports with PoE capability in a compact, rugged form factor. Designed for network-edge and industrial environments, it provides multi-gigabit connectivity and delivers power to connected devices over standard Ethernet cabling. This model targets installations that require more than gigabit speeds at the edge while maintaining reliable PoE power delivery for cameras, access control units, and IoT endpoints.

Advantages

The switch offers higher-than-GbE throughput on all ports, enabling improved bandwidth for video streams and data aggregation without replacing existing Cat5e/Cat6 cabling. Built for industrial deployment, it typically supports a robust operating temperature range and a compact footprint for DIN-rail or wall mounting. Integrated PoE simplifies installations by eliminating separate power supplies for endpoints and centralizes power management at the network edge. The device's multi-gigabit performance reduces congestion when connecting multiple high-bandwidth PoE devices to a central network.

Suitable for

• IP surveillance systems with multi-megapixel cameras requiring more than 1 Gbps uplink
• Access control and door systems with PoE-powered readers and controllers
• Industrial IoT gateways and sensors deployed at the network edge
• Small network aggregation points where compact PoE distribution is needed

Key specifications

• Port count: 3 x 2.5G Ethernet ports with PoE support
• PoE capability: Provides power over Ethernet to connected devices (per-port and total power depend on installation and power budget)
• Data rates: Multi-gigabit (2.5 Gbps) per port for increased throughput over standard GbE
• Form factor: Industrial-grade housing suitable for DIN-rail or wall mounting
• Network features: Layer 2 switching functionality suitable for edge aggregation
• Cabling: Compatible with standard Ethernet cabling (Cat5e/Cat6) for 2.5G operation

How to use

Install the switch in a suitable industrial enclosure or mount it on a DIN rail or wall bracket according to the site's mechanical and environmental requirements. Connect upstream network equipment to one of the 2.5G ports to provide uplink bandwidth, and connect PoE-powered devices such as IP cameras, access control readers, or IoT devices to the remaining ports using standard Ethernet cables. Ensure the total PoE power draw of connected devices does not exceed the available power budget of the switch. Configure any required VLANs or L2 settings from the network management interface or by integrating the switch into the existing network topology.

Recommendations

Place the switch close to the powered devices to minimize cable runs and power loss. Verify cable category supports 2.5G operation (Cat5e or better) and plan the PoE budget before deployment; distribute high-power devices across multiple switches if necessary. Use surge protection and adhere to industrial grounding practices to improve reliability in harsh environments.
