2-way PoE switch

A PoE 2-way switch is a network switch with two ports that delivers both data and electrical power over a single Ethernet cable to connected devices.

Overview

A PoE (Power over Ethernet) 2-port switch allows you to connect and power two network devices simultaneously using a single Ethernet cable per device, eliminating the need for separate power adapters . These switches are ideal for small setups, such as powering IP cameras, access points, or PoE-enabled routers in areas without convenient power outlets .

Key Features

• PoE Standards: Supports IEEE 802.3af (15W), 802.3at (30W), and in some models 802.3bt (up to 90W) for higher power devices .
• Connectivity: Typically uses RJ45 ports with auto-crossover, supporting 10/100 Mbps speeds with half/full duplex and auto-negotiation .
• Cable Requirements: Works with CAT5e or higher structured cabling, with a maximum distance of 100 meters per port .
• Deployment: Can be used indoors or outdoors depending on the model; some switches come in NEMA4/4X-rated enclosures for outdoor use .
• Power Source: PoE can be supplied from a midspan injector or another PoE switch, allowing flexible network design .

Benefits

• Simplified Installation: Reduces cable clutter by combining power and data in one cable .
• Cost-Effective: Eliminates the need for separate power supplies for each device.
• Flexibility: Ideal for small-scale deployments or extending PoE to areas without electrical outlets.
• Plug-and-Play: Many 2-port PoE switches are unmanaged, requiring no configuration, making them easy to deploy .

Example Product

The Altronix NetWay2ESWPN is a 2-port PoE/PoE+ switch that supports 802.3af, 802.3at, and 802.3bt standards, with RJ45 connectivity, CAT5e cabling, and a temperature range from -20ºC to 75ºC. It is suitable for powering two IP devices over a single structured cable and is rated for outdoor use .

In summary, a PoE 2-way switch is a compact, efficient solution for powering and networking two devices simultaneously, ideal for small installations or extending PoE to remote devices without additional power infrastructure.
