10/100Mbps Smart Switch With Gigabit Options
Where to buy

Description

16 or 24 10/100Mbps Ports
Each switch comes with 16 or 24 10/100Mbps ports designed for flexible connection and Ethernet/Fast Ethernet Integration. These intelligent ports detect the network speed and auto-negotiate between 10Base-T and 100Base-TX, as well as half- and full-duplex modes. The 10/100Mbps ports are ideal for segmenting the network into small, connected sub networks for superior performance, enabling the most demanding multi-media and imaging applications over the network.
 
Optional Gigabit Ports
These ports come as optional modules and can be installed in the open slot on the front of the switches. Available for  selection are 1000Base-SX, 1000Base-LX, 1000Base-T and GBIC ports (for flexible fibre connections). The Gigabit ports are capable of handling 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-balancing connection.
 
VLAN for Performance and Security
The switches support multiple port-based VLANs to extend the broadcast domain, segment network traffic and improve performance and manageability. This allows adds, moves and changes to be easily carried out. VLANs also provides security by limiting broadcast domains, traffic in different segments and subnets can be separated for maximum throughput and secure networking.
 
Workgroup Plug-and-Play
With 16 or 24 plug-and-play ports, the switch is a perfect choice for workgroups to upgrade performance in a client/server environment. The ports can be connected to servers in full-duplex or to hubs in half-duplex.
