Noise  free  fanless  design  for  home  and  SOHO  users

    Home and SOHO users are always working in a small and limited space,
    therefore, noise free fanless switch becomes necessary and important.

    Port 

7, 8 dual media ports are provided for flexible fiber connection. You can 

    select to install optional SFP transceiver modules in these cages for short,
    medium or long distance fiber backbone attachment. Use of the SFP will 
    disable their corresponding built-in 10/100/1000Base-T connections.

The switch supports not only Layer 2 802.1p Priority Queue control, but a

    supports programmable higher layer classification and prioritization to enable 
    enhanced Quality of Service (QoS) support for real time applications based on 
    information taken from Layer 2 to Layer 4, such as VoIP.

Port mirroring copies traffic from a specific port to a target port. This 

    mechanism helps track network errors or abnormal packet transmission 
    without interrupting the flow of data.

The VLAN feature in the switch offers the benefits of both security and 

    performance. VLAN is used to isolate traffic between different users and thus
    provides better security. Limiting the broadcast traffic to within the same
    VLAN broadcast domain also enhances performance.

 Q-in-Q, the use of 

    double VLAN tags is an efficient method for enabling Subscriber Aggregation. 
    This is very useful in the MAN. 

The Gigabit ports can be combined together to create a multi-link load-

    sharing trunk. Up to 4 Gigabit ports can be set up per trunk for bandwidth up 
    to 8Gbps,

 all traffic is aggregated based on MAC addresses, thus balancing 

    the traffic load

. The switch supports up to 4 trunking groups. Port trunks are

    useful for switch-to-switch cascading, providing very high full-duplex speeds

.

802.1x features enable user authentication for each network access attempt. 

    Port security features allow you to limit the number of MAC addresses per 
    port in order to control the number of stations for each port. Static MAC 
    addresses can be defined for each port to ensure only registered machines 
    are allowed to access. By enabling both of these features, you can establish 
    an access mechanism based on user and machine identities, as well as 
    control the number of access stations.

For mission critical environments with multiple switches supporting STP, you

    can configure the switches with a redundant backup bridge path, so
    transmission and reception of packets can be guaranteed in event of any 
    switch on the network.
