An 8-port industrial PoE++ switch can deliver up to 90 W per port, with a total power budget typically around 480 W.

Per-Port Power

Industrial switches with PoE++ (IEEE 802.3bt Type 4) can supply up to 90 watts of DC power per port, allowing connected devices such as IP cameras, wireless access points, and sensors to operate without separate power sources (Axis D8208-R, Perle IDS-108HP) . Earlier PoE standards provide lower power: IEEE 802.3af delivers 15.4 W per port, and IEEE 802.3at (PoE+) delivers up to 30 W per port .

Total Power Budget

The total power budget of an 8-port industrial switch depends on the model. For example, the Axis D8208-R switch has a total PoE budget of 480 W, meaning all eight ports can simultaneously deliver maximum power if needed . Other industrial switches may have lower budgets depending on design and energy efficiency features, such as WAGO ECO switches, which adjust power consumption automatically based on network load .

Industrial Considerations

Industrial switches are designed for harsh environments, with features like wide temperature tolerance (-40°C to 60°C), shock and vibration resistance, and redundant power supply options . They often include management features for monitoring power usage, rebooting devices, and ensuring uninterrupted operation in mission-critical applications .

Summary

• Per-port PoE++ power: up to 90 W
• Total power budget: typically 480 W for 8 ports
• Standards supported: IEEE 802.3af (15.4 W), IEEE 802.3at (30 W), IEEE 802.3bt PoE++ (90 W)
• Industrial features: ruggedized design, wide temperature range, shock/vibration resistance, optional redundant power These specifications make 8-port industrial switches ideal for compact, high-power deployments in industrial, outdoor, and surveillance environments.
