ALLNET industrial PoE switch ALL-SGI8112PMJ 8+4 ports

ALLNET industrial PoE switch ALL-SGI8112PMJ 8+4 ports is a rugged network device designed to provide stable Ethernet connectivity and Power over Ethernet (PoE) in demanding environments. The unit combines eight PoE-enabled ports with four additional Ethernet ports to support mixed device installations such as IP cameras, wireless access points and industrial controllers. Its construction and feature set target continuous operation in industrial, surveillance and building automation networks where reliable data and power delivery are required.

Advantages

The switch delivers combined data and power over standard Ethernet cabling, reducing the need for separate power supplies at the edge. Its industrial-grade enclosure and components improve resistance to vibration, temperature variations and electromagnetic interference compared to consumer switches. With multiple PoE ports and separate uplink ports, the device simplifies network topology by supporting both powered endpoints and non-powered network devices within the same switch.

Suitable for

• IP video surveillance systems with multiple PoE cameras
• Wireless access point deployments in commercial or industrial sites
• Building automation and access control networks
• Small to medium industrial networks requiring mixed PoE and non-PoE connectivity

Key specifications

• Port count: 8 PoE-enabled ports plus 4 additional Ethernet ports
• PoE support: provides power to compatible end devices over Ethernet cabling
• Mounting: suitable for DIN-rail or rack/flat surface installation depending on model configuration
• Construction: industrial-grade metal housing for enhanced durability
• Operating conditions: designed for extended temperature and vibration tolerance typical of industrial deployments
• Data forwarding: hardware switching for real-time Ethernet traffic handling

How to use

Install the switch in a suitable industrial cabinet, on a DIN rail or a stable surface following local installation standards. Connect PoE-capable devices to the PoE-enabled ports using standard Ethernet cables and connect additional non-PoE network devices to the remaining Ethernet ports. Use the uplink ports to integrate the switch into the wider network via a router, core switch or network aggregator. Ensure the ambient environment and power source meet the device's operating specifications before powering on.

Recommendations

Plan PoE power budget according to the power requirements of connected devices, distribute high-power endpoints across ports to avoid exceeding per-switch or per-port power limits, and use shielded cabling in electrically noisy environments. Regularly check firmware updates and perform preventive maintenance in line with on-site operational procedures.
