8 10/100Mbps Ports
The switch comes with 8 10/100Mbps ports designed for flexible connection and Ethernet/fast Ethernet integration. These intelligent ports detect the network
speed and auto-negotiate between 100BASE-TX and 10BASE- T, as well as full- and half-duplex. The 10/100Mbps ports are ideal for segmenting the network into small, connected sub networks for superior performance, enabling the most demanding multimedia and imaging applications over the network.
2 Gigabit Fiber Ports
2 1000BASE-SX Gigabit ports are provided to handle very large amounts of data in a secure topology linking to a backbone or high-power servers.
High-bandwidth Port Trunking
Multiple ports can be combined into a high- bandwidth, full-duplex trunk for switch-to-switch or switch-to-server connection. Port trunking gives users the high-speed load- sharing connection.
VLANs for Performance and Security
The switch supports up to multiple port-based VLAN s to extend the broadcast domain, segment network traffic and improve performance and manageability.
This allows adds, moves and changes to be easily carried out. It also provides security by limiting broadcast domains, traffic in different segments and subnets can be separated for maximum throughput and secure networking.
Plug-and-Play with Easy Configuration
The switch provides plug-and-play connection to mixed bandwidth workgroups while letting the administrator easily set up port trunking and VLAN groups via a built-in console port.
