| A switch is a device with which it is possible to connect computers into a (local area) network, provided your computers all have an appropriate networking device installed. Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resourses with your entire home or office network. |

The DEM-420X is compliant with IEEE 802.3ae 10Gb/s standards. With the optional XFP transceivers, this module will enable the switch to connect to distant networks and backbones. It supports all Layer 2/3/4 functionalities equipped in the compatible switches; some of the functions include SNMP, VLAN ID, Port Mirroring, QoS and Link Aggregation. Furthermore, the DEM-420X transmits and distributes data frame packets at Layer 2, 3, and 4, incorporating switching and routing technologies.
The DEM-420X also includes an informative LED-Light indicator displaying 10Gigabit mode link and activity. When using D-Link▓s XFPs, each transceiver can be removed or added without powering down the switch, enabling network management without any down time.
