The SW-26210 is 24-port 10/100M with PoE + 2 Combo Gigabit Copper / 2 SFP Rack-mount Gigabit Ethernet Switch that is designed for medium or large network environment. The SW-26210 features IEEE 802.3af Power over Ethernet (PoE) ports supplying a maximum of 390 watts, converting standard 100~240V/AC power into low-voltage DC to power network devices. PoE awareness means transmitting power only when compliancy of devices is verified, or else only the data will be sent through LAN cable. By adding SW-26210 to existing networking, installing networking products such as Access Points and IP cameras is simple. Wireless device deployments are easily located within range of available power outlets and negating the use of heavy AC power adapters.
