● Provide -48V DC power for powered devices (PDs), such as IP Phones, WLAN APs, and Bluetooth APs.
● Compatible with both IEEE802.3at(30W) and IEEE802.3af(15.4W), can supply power to PDs under these two standards.
● Automatically detect and supply power to IEEE802.3at and IEEE 802.3af compliant powered devices(PDs).
● Only supply power to IEEE 802.3af/at compliant PDs, no worry about damaging other private standard PoE devices or devices without PoE function.
● Support port power supply prioritization, guarantee the continuous power supply of key nodes.
● Up to 100m network cable transmitting distance, support flexible network expansion without power line deployment concerns. Users can freely fix their wireless APs, IP cameras or other end devices on the wall or ceiling.
● Support short-circuit protection function, the switch will automatically start short-circuit function and cut off the power supply when there is high-current or other power failures, which can efficiently defend against device damage or network failures caused by line fault or wrong installation.
● POE intelligent strategy: POE intelligent diagnosis, POE timing restart, Power supply schedule.
● Support CLI Management ,SNMP Management, simple WEB management, easy to configure the functions of switches.
