Chapter 1: Introduction Congratulations on your purchase of the NetComm 10/100/1000Mbps Gigabit Ethernet Web Smart Switch, available in either 16-Port or 24-Port models. This device integrates 1000Mbps Gigabit Ethernet, 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible package.
Switching Technology Another approach to pushing beyond the limits of standard Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network.
VLAN (Virtual Local Area Network) A VLAN is a group of end-stations that are not constrained by their physical location and can communicate as if a common broadcast domain, a LAN. The primary reason for using a VLAN is to reduce latency and the need for routers. Other VLAN benefits include: Security Security is increased with the reduction of opportunity in eavesdropping on a broadcast network, because data will only be switched to those confidential users within the VLAN.
Features ■ Depending on your model, either 16 or 24×10/100/1000Mbps Auto-negotiation Gigabit Ethernet ports ■ All RJ45 ports support auto MDI/MDIX, so there is no need to use cross-over cables or an uplink port ■ Full/half duplex transfer mode for 10/100Mbps port ■ Full duplex transfer mode for Gigabit port ■ Wire speed reception and transmission ■ Store-and-Forward switching scheme capability to support rate adaptation and ensure data integrity ■ Up to 4K unicast addresses entities per device, self-learnin
Package Contents Open the shipping cartons of the Switch and carefully unpacks its contents.
Chapter 2: Installation The location where you install the switch stack may greatly affect its performance, therefore we suggest you consider the following before you install your switch: ■ Install the Switch in a fairly cool and dry place. See Technical Specifications for the acceptable temperature and humidity operating ranges. ■ Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.
