ALLNET ALL-SGI8120PM Industrial PoE+ Switch 20+4 Ports 10/100/1000 Mbps

The ALLNET ALL-SGI8120PM Industrial PoE+ Switch provides 20 Power over Ethernet Plus (PoE+) ports together with 4 dedicated uplink gigabit ports, supporting 10/100/1000 Mbps on all uplinks. Designed for industrial and enterprise deployments, this switch combines centralized power delivery and reliable data connectivity to simplify installation of networked devices. It is intended for environments that require continuous operation and convenient deployment of IP cameras, wireless access points, VoIP phones and other powered Ethernet equipment.

Advantages

This industrial PoE+ switch supplies data and power over a single Ethernet cable to compatible devices, reducing separate power cabling and installation time. With 20 PoE+ ports it supports higher power budgets per port than standard PoE, enabling operation of PTZ cameras and higher-power wireless access points. The four gigabit uplink ports provide sufficient bandwidth for aggregated traffic to core switches or network video recorders. The rugged design and enterprise-grade feature set support stable operation in demanding network environments.

Suitable for

• Surveillance systems with multiple IP cameras
• Wireless access point deployments in enterprise and campus networks
• VoIP phone systems and unified communication endpoints
• Industrial automation networks requiring powered devices
• Edge aggregation for small to medium installations

How to use

Install the switch in a suitable rack or mounting location following the site’s environmental and safety requirements. Connect powered devices such as IP cameras, access points or phones to the PoE+ ports using standard Ethernet cables; the switch will provide both power and data over the same cables. Use the four gigabit uplink ports to connect to the network core, a router or a network video recorder to aggregate traffic. Configure basic network settings, VLANs, and PoE power allocation as required via the management interface or console if management features are provided by the model.

Recommendations

Plan PoE budget and cable lengths in advance: verify each device’s power draw to ensure the total available PoE power covers all connected devices, and use appropriate quality Ethernet cabling for reliable gigabit performance.
