48 port Gigabit Manageable PoE switch with 10G SFP+ Slot

Model: LNK-4048G



High-performance of both hardware and software

This 10G PoE switch uses top-rated 10G network switching chip, multiple layers PCB design, as well as self-developed switch software system. With combination of hardware and software, it improves product quality from forwarding stability, packet processing speed, and other work capability.


Support the fast ring network protocol, free configuration

The switch supports stable and reliable fast Ring Protection Protocol(RSTP). It Achieved real ring loop redundancy protection. Besides, there is no need to configure 10G port when users using this switch, to reduce probability of network failure.


Strong network security

Support dynamic or static binding by users’ definition, such as IP, MAC, VLAN, PORT, etc. Support port isolation, to prevent communication between two neighbor network equipment within the same broadcast domain , for reducing network risk; Supports perfect storm control function which can suppress broadcast, multi-cast, and uni-cast storm; Support specific ARP inspection which can effectively prevent ‘‘ARP spoofing attack’’ created by hackers or attackers via ARP packets.


Convenient management and maintenance
By easy WEB interface(http and https protocol supported), you can conveniently operate and configure all kinds of function in this switch. Support management by CLI, Telnet, Console port, which is more suitable for professional network administrator; It also allow reset by one-press, making maintenance easier.
