PoE Smart Business Switch 

Buffalo's BS-GSP Series of Multi-Port Gigabit PoE Smart Switches offer an easy and cost-effective way to extend your business network at gigabit speeds with advanced management features and the convenience of Power over Ethernet.



Buffalo's Gigabit Green Ethernet Switches include power-savings features, like 802.3az Green Ethernet technology and an energy conservation feature that monitors the activity status of each port to reduce the total power consumed, therefore reducing related operational costs.

Gigabit speeds, eco-minded operation, performance-minded features and a lifetime warranty make Buffalo's BS-GU Series of Gigabit Green Ethernet Switches a perfect network extension solution for your office.


Jumbo frame support and full duplex operation provide maximum performance for a total switching capacity of up to 48 Gbps on the BS-GS2024P.

Buffalo's Gigabit Green Ethernet High Power PoE Switches come with a compact and durable all metal chassis and are fan-less which provides silent and reliable operation. Buffalo's lifetime warranty* ensures that you will never have to replace your switch due to defects.


Buffalo's BS-GUP series of Gigabit Green Ethernet High Power PoE Switches offers network design flexibility without the reliance of AC power through its high power PoE feature.  Many devices including routers, surveillance cameras andhome automation equipment can be powered through PoE which allows you to place these devices anywhere in your home or office, regardless of whether there is an AC outlet available.  In addition, the fact that PoE eliminates additional AC power cables reduces clutter and gives your home or office a cleaner appearance.


Multiple gigabit Ethernet ports provide fast transfer rates of large bandwidth intensive files including graphics and multimedia.


Integrates any Ethernet enabled device with plug and play setup including PCs, TVs, gaming consoles and other digital home appliances.


Easy to read LED indicators for each port clearly and quickly communicate which ports have active connections as well as which ports have gigabit speed devices attached.  Auto-MDIX provides fast plug and play setup, eliminating the need for a crossover cable while auto-negotiation detects the link speed of the attached device and adjusts for compatibility and optimal performance, making the switch backwards compatible with older network devices.


802.3az Green Ethernet technology monitors the link status of each port and only provides power to those that have a connected device that is powered on and puts transmitters into sleep mode when no information is being sent or received.  In addition, the length of cable connected to each port is detected and the amount of power supplied is adjusted accordingly.  All of these features add up to energy savings of up to 79% over traditional switches.
