JS-SW28K3-U4G24MP Gigabit management POE switch

Product overview

JS-SW28K3-U4G24MP is a Gigabit managed PoE switch, providing 28 10/100/1000M adaptive RJ45 ports and 4 Gigabit SFP fiber slots, 4 10/100/1000M adaptive RJ45 ports and 4 thousand Mega SFP optical fiber slots form Combo. Each RJ45 port supports MDI/MDIX auto flip and wire-speed forwarding functions. Ports 1-24 support the IEEE802.3af/at standard PoE power supply function, which can automatically detect and identify the power receiving equipment that meets the standard, and supply power to it through the network cable.

Provide a comprehensive security protection system, perfect QoS strategy and flexible VLAN function, simple management and maintenance, to meet the access and networking requirements of enterprises, communities, hotels, office networks and campus networks, suitable for hotels, campuses, factory dormitories and middle Small businesses build cost-effective networks. Support Jetstor SmartLink power management function, can activate the PoE port priority mechanism when the system is overloaded with power supply, cut off the power supply of the ports that exceed the power range and have lower priority, ensure priority power supply to key devices, and avoid overloaded operation , In order to protect the switch.

Features

1、Support multiple management methods such as Web network management, Telnet, SNMP, Console, etc., quickly and conveniently realize network management;

2、Power management and step-by-step startup function escort the safe and stable operation of Jieke PoE switches;

3、Support IEEE802.3 af/IEEE802.3 at standard PoE power supply;

4、The maximum power supply for a single port is 30W;

5、Automatic detection and identification of standard PoE power receiving equipment, intelligent power supply, will not burn non-standard PoE power receiving equipment or ordinary equipment;

6、Support port power supply priority to ensure continuous power supply for key nodes in the network;

7、Support IEEE802.3x full-duplex flow control and half-duplex flow control.
