should be such that a hazardous condition is not achieved due
to uneven mechanical loading.
d) Circuit Overloading- Consideration should be given to the
connection of the equipment to the supply circuit and the effect
that overloading of circuits might have on over current protection
and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this
concern.
e) Reliable Earthing-Reliable earthing of rack-mounted
equipment should be maintained. Particular attention should be

Introduction
This chapter describes the features of the 16-Port
10/100/1000Mbps Gigabit Ethernet Web Smart 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 environments, 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 to coping with the network bottlenecks that
frequently develop as computers and their busses get faster and
more users use applications that 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 optical fiber 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 and tomorrow’s rapidly improving switching and routing
internetworking technologies. And with expected advances in
the coming years in silicon technology and digital signal
processing that will enable Gigabit Ethernet to eventually
operate over unshielded twisted-pair (UTP) cabling, outfitting
your network with a powerful 1000-Mbps-capable
backbone/server connection creates a flexible foundation for the
next generation of network technology products.
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity
of desktop computing applications are fueling the need for high
performance networks. A number of high-speed LAN
technologies have been proposed to provide greater bandwidth
and improve client/server response times. Among them,
100BASE-T (Fast Ethernet) provides a non-disruptive, smooth
evolution from the current 10BASE-T technology. The
non-disruptive and smooth evolution nature, and the dominating
potential market base, virtually guarantees cost-effective and
high performance Fast Ethernet solutions.
100Mbps Fast Ethernet is a standard specified by the IEEE
802.3 LAN committee. It is an extension of the 10Mbps
Ethernet standard with the ability to transmit and receive data at
100Mbps, while maintaining the CSMA/CD Ethernet protocol.
Since the 100Mbps Fast Ethernet is compatible with all other
10Mbps Ethernet environments, it provides a straightforward
upgrade and takes advantage of the existing investment in
hardware, software, and personnel training.

Switching Technology
Another key development pushing the limits of Ethernet technology is in
the field 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. A switch increases
capacity and decreases network loading by making it possible for a
local area network to be divided into different segments which don’t
compete with each other for network transmission capacity, giving a
decreased load on each.
The switch acts as a high-speed selective bridge between the individual
segments. Traffic that needs to go from one segment to another is
automatically forwarded by the switch, without interfering with any other
segments. This allows the total network capacity to be 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)
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 utility of using VLAN is to
reduce latency and need for routers, using faster switching
instead. Other VLAN utility includes:
Security, Security is increased with the reduction of opportunity
in eavesdropping on a broadcast network because data will be
switched to only 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) VLAN is the common method of
implementing a VLAN, and is the one supplied in the Switch.
