Introduction  
This chapter describes the features of the Switch and some back-  
ground information about Ethernet/Fast Ethernet/Gigabit Ethernet  
switching technology.  
Fast Ethernet Technology  
The growing importance of LANs and the increasing complexity of  
desktop computing applications are fueling the need for high perfor-  
mance 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 guarantee  
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 envi-  
ronments, it provides a straightforward upgrade and takes advantage  
of the existing investment in hardware, software, and personnel train-  
ing.

Gigabit Ethernet Technology  
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the  
same packet structure, format, and support for CSMA/CD proto-  
col, 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  
are essential to coping with the network bottlenecks that frequently  
develop as computers and their busses get faster and more users  
using applications that generate more traffic. Upgrading key compo-  
nents, 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 supports video conferencing, complex imaging, and  
similar data-intensive applications. Likewise, since data transfers  
occur 10 times faster than Fast Ethernet, servers outfitted with Giga-  
bit Ethernet NIC’s are able to perform 10 times the number of opera-  
tions in the same amount of time.  
The phenomenal bandwidth delivered by Gigabit Ethernet was the  
most cost-effective method to take advantage of today’s rapidly  
improving switching and routing internetworking technologies. And  
with expected advances in silicon technology and digital signal pro-  
cessing that enabled 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.

Switching Technology  
Another approach to pushing beyond the limits of Ethernet technol-  
ogy 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 seg-  
ments.  
Switching is a cost-effective way of increasing the total network  
capacity available to users on a local area network. A switch in-  
creases 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 indi-  
vidual 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 previ-  
ous generation of network bridges, which were characterized by higher  
latencies. Routers have also been used to segment local area net-  
works, 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.

Installation  
The site where you place the Switch may greatly affect its perfor-  
mance. When installing, take the following into your consideration:  
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 electromag-  
netic 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 hub and protect the hub case from scratch-  
ing.

Connecting Network Cable  
The Switch supports 10/100/1000Mbps Gigabit Ethernet. It runs  
full/half duplex transfer mode for 10/100Mbps and full duplex trans-  
fer mode for 1000Mbps.  
These ports are Auto-MDI type port. The Switch can auto trans-  
form to MDI-II or MDI-X type, so you can just make an easy  
connection that without worrying if you are using a standard or  
crossover cable.  
AC Power  
The Switch can be used with AC power supply 100-240VAC, 50-60  
Hz. The power switch is located at the rear of the unit adjacent to the  
AC power connector and the system fan. The switch’s power sup-  
ply will adjust to the local power source automatically and may be  
turned on without having any or all LAN segment cables connected.
