Fast Ethernet Smart managed switch DES-1210-28P is equipped with 24 10/100Base-T ports with PoE power supply support, 2 10/100/1000Base-T ports and 2 Gigabit combined 10/100/1000Base-T/SFP ports. The DES-1210-28P switch is IEEE 802.3af and IEEE 802.3at compliant for Power over Ethernet (PoE) and provides up to 30W on ports 1-4 and up to 15.4W on ports 5-24. The total PoE power of the switch is 193W. PoE/PoE+ ports can power devices such as IP phones, wireless Wi-Fi access points and IP cameras directly through Ethernet cables, making their deployment much easier.
