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.
In this guide, the term “Switch” (first letter upper case) refers to your 16 or 24 Port 10/100/
1000Mbps Gigabit Ethernet Web Smart Switch, and “switch” (first letter lower case) refers to other
Ethernet switches.
This chapter describes the features of your new Switch and some background information about
Ethernet/Fast Ethernet/Gigabit Ethernet switching technology.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format,
and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a
tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase
over 10-Mbps Ethernet. Since it is compatible with all 10-Mbps and 100-Mbps Ethernet environ-
ments, Gigabit Ethernet provides a straightforward upgrade without wasting a company’s existing
investment in hardware, software and trained personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet is essential for coping with
network bottlenecks that frequently develop as computers and get faster and more applications
generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit
Ethernet can greatly improve network response times as well as significantly speed up the traffic
between your subnets.
Gigabit Ethernet enables fast ethernet connections to support video conferencing, complex imaging,
and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast
Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the number of
operations in the same amount of time.
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective
method to take advantage of today’s and tomorrow’s rapidly improving switching and routing
internetworking technologies.

Switching Technology
Another approach to pushing beyond the limits of standard Ethernet technology is the development
of switching technology. Aswitch 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. Aswitch increases capacity and decreases network loading by dividing a local area
network into different segments, which don’t compete with each other for network transmission
capacity.
The switch acts as a high-speed selective bridge between the individual segments. The switch,
without interfering with any other segments, automatically forwards traffic that needs to go from one
segment to another. By doing this the total network capacity is multiplied, while still maintaining the
same network cabling and adapter cards.
Switching LAN technology is a marked improvement over the previous generation of network
bridges, which were characterized by higher latencies. Routers have also been used to segment local
area networks, but the cost of a router, the setup and maintenance required make routers relatively
impractical. Today switches are an ideal solution to most kinds of local area network congestion
problems.

VLAN (Virtual Local Area Network)
AVLAN 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.
Cost Reduction VLANs can be used to create multiple broadcast
domains, thus eliminating the need of expensive routers.
Port-based (or port-group) Port-based is the common method of implementing a
VLAN, and is the one supplied in the Switch.

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.
■Leave at least 10cm of space at the front and rear of the hub for ventilation.
■Install the Switch on a sturdy, level surface that can support its weight, or in an EIA standard-size
equipment rack. For information on rack installation, see the next section, Rack Mounting.
■When installing the Switch on a level surface, attach the rubber feet to the bottom of each device.
The rubber feet cushion the switch and protect the switch case from scratching.
Rack Mounting
The switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring
closet with other equipment. Attach the mounting brackets to the switch’s front panel (one on each
side), and secure them with the screws provided.
Figure 1. Combine the Switch with the provided screws
Then, use screws provided with the equipment rack to mount each switch in the rack.

NetComm16or24portGigabitSwitch YML711Rev1

Figure 2. Mount the Switch in the rack
Connecting Network Cable
The Switch supports 1000Mbps Gigabit Ethernet that runs in Auto-negotiation mode, 10Mbps
Ethernet or 100Mbps Fast Ethernet that runs both in half and full duplex mode, and 1000Mbps
Gigabit Ethernet that runs in full duplex mode using four pair of Category 5 Cable.
☞Important Note:
Some Category 5 cables are only prepared with two pairs (4 wires) of
interconnection wires which are not suitable for Gigabit Ethernet over
Category 5 cables.
In order to use the full performance of this switch in Gigabit mode, please
ensure that your cabling uses four pairs (8 wires). The switch’s RJ-45 ports
are Auto-MDI and will auto negotiate between 10Mbps, 100Mbps and
1000Mbps depending on the type of cable and connection. The Switch can
auto transform to MDI-II or MDI-X, so there is no need to use cross-over
cables or an up-link port.
AC Power
The Switch usesAC power 240VAC, 50 Hz. The power switch is located at the rear of the unit
adjacent to the AC power connector and the system fan. The Switch may be turned on without
having any or all LAN segment cables connected.

LED Indicator: Comprehensive LED indicators display the status of the
switch and the network (see the following LED Indica-
tors section).
Gigabit Ethernet Ports (1~16 or 1~24): Depending on which model you have purchased, the
Switch has 16 or 24 Gigabit twisted pair ports, supported
auto negotiable 10/100/1000Mbps and auto MDI/MDIX
crossover detection function. This supplies true “plug
and play” capability. These ports operate in half-duplex
mode for 10/100Mbps and full- duplex mode for 10/100/
1000Mbps.
Note: When the port is set to “Forced Mode”, the Auto MDI/MDIX feature will be
disabled.
