  • 48+4 10G Management Fiber Ethernet Switch 


    Product overview 

    JHA-SW4804MG-52VS is a BCM chip series standard switch.

    The modular design provides 48 10/100/1000 adaptive ports and 4 integrated terabyte optical ports, providing sufficient bandwidth for the data exchange between the aggregation and the core.

    Provide high capacity exchange capacity, perfect security control policy and CPU protect policy to improve fault tolerance, and ensure the stable operation of network and load balance of link.

    Meanwhile, it supports automatic DoS attack prevention and SNMP, IEEE 802.1, spanning tree, fast spanning tree protocol, link aggregation and other functions.


     Product features 

    Ø limit the number of port maximum connection between a host and the Ethernet interface for multiple binding, increase bandwidth and system redundancy

    Ø powerful ACL, support L2 – L4 layer data filteringØ   

     Policy control list, flow regulation

    8.Easy to use and maintain

    It can be managed by Web, SNMP and so on

    Ø support XModem protocol, can through the TFTP/ZMODEM software upgrades and the BootRom

    Ø support SFP +, as well as backward compatibility XFP, etc

    9.Strong traffic and broadcast management

    Automatic detection and suppression of broadcast storm, support IGMP message detection, effectively limit broadcast message flooding

    Ø supports full-duplex mode and half duplex mode of flow control

    Ø support Ethernet interface in 1 m as the rate limiting step length
