Key Features: 28-port gigabit PoE switch with 24 port gigabit PoE + 2 port gigabit RJ45 uplink + 2 port gigabit SFP uplink, using high-quality high-speed network IC and the most stable PoE chip, PoE port meets IEEE802.3af/at standard, The network provides a seamless connection, and the PoE power port can automatically detect and power the powered devices that comply with the IEEE802.3af/IEEE802.3at standards. The non-POE device intelligently detects no power and only transmits data. 24* 10/100/1000M PoE Ports + 2* Gigabit RJ45 Uplink Port + 2* Gigabit SFP Uplink Port Support IEEE802.3、IEEE802.3u、IEEE802.3x、IEEE802.3ab、IEEE802.3zCompatible with IEEE802.3at (30W) and IEEE802.3af (15.4W)Ethernet port supports 10/100/1000Mbps adaptive and PoE functionsFlow control mode: full-duplex adopts IEEE 802.3x standard, half-duplex adopts Back pressure standardSupport port auto flip (Auto MDI/MDIX)All ports support wire-speed switchingAutomatically supplied to adaptive devices1-24 port support port-based VLANSupport 19'' 1U rack mount PoE Devices Auto Detection MokerLink 24 port gigabit PoE switch compatible with IEEE 802.3af/at protocol, it determines and delivers the exact power supply to your devices with up to 30W power output on one PoE port. If a device not IEEE802.3af/at compliant, only network data will be transmitted through the LAN cable to avoid from being damaged by incorrect power sending. PoE Wathdog(PD Lifeguard) The PoE switch uses intelligent technology to monitor in real time the status of PoE devices. Once the poe devices stops working and does not respond to the switch, the switch will automatically reboot the PoE power to reboot the PoE devices, making managment easier. Port-based VLAN When you enable the extend mode with DIP switch(chiange to V), switch divides traffic for ports 1-24 to prevent PoE devices muliticast or broadcast storm from affecting each other. Full Gigabit Ports 24 port PoE switch includes 24 gigabit ports and 4 gigabit uplink port, it is use for applications that also require high data throughput due to the use of high-resolution camera. Furthermore, the devices support jumbo frames, which enables an additional increase in efficiency in networks with high data volumes. Opation Over Wide Temperature Ranges Unique design make sure PoE switch long-term stable operation over temperature spans of -10 and +55°C. SFP Modual Support 24 port gigabit PoE switch support up-link SFP ports, The switch's port 27-28 use fiber cable to connect wired network segments throughout buildings or across campuses extending beyond the limitations of Ethernet cabling. Good Heat Dissipation The 24 port gigaibt poe switch fetures with cooling fan, Through the fan cooling technology, the flow rate of the fluid in the convection process increases, greatly increasing the rate of heat emission. An external device integrated into a switch to bring in forced air when natural convection is insufficient to dissipate heat. Support 19'' Rack Mount Support rack-mount in 19'' cabinet, and includes all the necessary mounting hardware in the box .Save your space and easy to manage. Lighting Protection The PoE switch fetures with 6KV power port surge protection and 2KV network port surge protection can adapt to harsh outdoor environment and ensure the reliability of the uninterrupted network system.
