Switch UMD-S21022P150

Switch UMD-S21022P150


UMD-S21022P150  are Managed PoE switches support both 10/100M ports and 10/100/1000M ports;

All of the copper ports of the UMD-S21022P150 provide PoE Power Injector function,complying with IEEE 802.3at compliant powered devices with maximum up to 30 watts of power per port. The Switches also come with 2 SFP slots expanding your network flexibly. In addition, it provides high performance, enterprise-level QoS, advanced security strategies. With all these advanced features, the UMD-S21022P150 PoE Switch are ideal choice for small and medium business networking.

With UMD-S21022P150 PoE Switches, you are free to position equipments wherever they should be and power to the unit with the data over the Ethernet cable, not being limited by the power outlet. You can remotely reboot the device without having to climb up to or go to the device - just remove its Ethernet cable from the switch end as adopting PoE.

All ports UMD-S21022P150 PoE Switches are auto-sensing that make each port only provide power as detecting the presence of IEEE 802.3af /at PoE supported devices.


■UMD-S21022P150: Max Output Power: 150W, supports at most 8* 802.3af-compliant powered devices(power/port: 15.4W) or 4*802.3at-compliant powered devices(power/port:30W)

■Compatible with both IEEE802.3at(30W) and IEEE802.3af(15.4W), can supply power to PDs under these two standards;

■Transmitting electronic power together with data through a single network cable, free of power lines;

■Automatically detect and supply power to IEEE802.3at and IEEE 802.3af compliant powered devices(PDs);

■Advanced SAFC function, 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;

■Built-in PSE power supply module, plug-and play design, easy to install;

■High security performance defending against power surge;

■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;

■Energy-saving green design, support auto-switch to standby mode and auto-detect cable length. It will stay in standby mode and save the power when the port is disconnected , or provide a lower transmission power when the network cable is less than 10m;

■Support simple WEB management, easy to configure the functions of switches.
