This chapter describes the features of the Switch and some
background information about Ethernet/Fast 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
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
guarantee cost effective and high performance Fast Ethernet solutions
in the years to come.
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. Some of the 100Mbps
Fast Ethernet products (10/100Mbps dual-speed) are compatible with
10Mbps Ethernet environments; they provide a straightforward
upgrade and take advantage of the existing investment in hardware,
software, and personnel training.
Switching Technology
Another approach to pushing beyond the limits of 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
3
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 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.
For Fast Ethernet networks, a switch is an effective way of eliminating
problems of chaining hubs beyond the “two-repeater limit.” A switch
can be used to split parts of the network into different collision
domains, making it possible to expand your Fast Ethernet network
beyond the 205-meter network diameter limit for 100BASE-TX
networks. Switches supporting both traditional 10Mbps Ethernet and
100Mbps Fast Ethernet are also ideal for bridging between the
existing 10Mbps networks and the new 100Mbps networks.
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.
Features
The Switch was designed for easy installation and high performance
in an environment where traffic on the network and the number of
user increase continuously.
4
The Switch with its small, compact size was specifically designed for
small to mid size workgroups. This Switch can be installed where
space is limited; moreover, they provide immediate access to a rapidly
growing network through a wide range of user-reliable functions.
The Switch is ideal for deployment with multiple high-speed servers
for shared bandwidth 10Mbps or 100Mbps workgroups. With the
highest bandwidth 200Mbps (100Mbps full-duplex mode), any port
can provide workstations with a congestion-free data pipe for
simultaneous access to the server.
The Switch is expandable by cascading two or more switches
together. As all ports support 200Mbps, the Switch can be cascaded
from any port and to any number of switches.
The Switch is a perfect choice for site planning to upgrade to Fast
Ethernet in the future. Ethernet workgroups can connect to the Switch
now, and change adapters and hubs anytime later without needing to
change the Switches or reconfigure the network.
The Switch combine dynamic memory allocation with store-andforward switching to ensure that the buffer is effectively allocated for
each port, while controlling the data flow between the transmit and
receive nodes to guarantee against all possible packet loss.
The Switch is an unmanaged 10/100 Fast Ethernet Switch that offers
solutions in increasing small Ethernet/Fast Ethernet workgroup
bandwidth. Other key features are:
?? Store and forward switching scheme capability. As the result
of complete frame checking and error frame filtering, this
scheme prevents error packages from transmitting among
segments.
?? Auto-MDI function supports automatic MDI-II/MDI-X
(crossover) detection function gives true ‘plug and play’
capability without the need of confusing crossover cables or
crossover ports.
5
?? Auto-negotiation for any port. This allows for auto-sensing of
speed (10/100Mbps) thereby providing you with automatic and
flexible solutions in your network connections.
?? Flow control for any port. This minimizes dropped packets by
sending out collision signals when the port’s receiving buffer is
full. Note that flow control is only available in half duplex
mode.
?? Data filtering rate eliminates all error packets, runts, etc., per
port at wire-speed for 100Mbps speed.
?? Data filtering rate eliminates all error packets, runts, etc., per
port at wire-speed for 10Mbps speed.

C ONNECTING T HE S WITCH
This chapter describes how to connect the Switch to your Fast
Ethernet network.
PC to Switch
You can connect a PC to the Switch via a two-pair
Category 3, 4, 5 UTP/STP cable (use Category 5 for
100Mbps connection). You can connect the PC
(equipped with a RJ-45 10/100Mbps Fast Ethernet adapter)
to any of the ports. When connecting PC to the Switch, the
Switch’s Port LED indicator will light according to the
network adapter’s connection speed. If the port LED
indicator does not light after making a proper connection,
check the PC network card, the cable, and the Switch’s
functionality.
Hub to Switch
You can connect Ethernet hub(s) (10BASE-T or
100BASE-TX) to the Switch via a two-pair Category 3,
4, 5 UTP/STP cable (use Category 5 for 100Mbps
connection). The connection is accomplished from the
any RJ-45 port on the hub to any RJ-45 port on the
Switch. After connecting the hub to the Switch, the
Switch’s Port LED indicator will light according to the
hub’s connection speed. If the port LED indicator does
not light after making a proper connection, check the
hub, the cable, and the Switch’s functionality. Each
10
port on the Switch has auto-MDI function; you can
make the connection using crossover or straight
through cable with uplink port or regular port from
the hub.
Switch to switch (or other devices)
You can connect switch(s) or other Ethernet device(s)
(10BASE-T or 100BASE-TX) to this Switch via a twopair Category 3, 4, 5 UTP/STP cable (use Categ ory 5
for 100Mbps connection). The connection is
accomplished from the any RJ-45 port on the device to
any RJ-45 port on the Switch. After connecting the
hub to the Switch, the Switch’s Port LED indicator will
light according to the hub’s connection speed. If the
port LED indicator does not light after making a
proper connection, check the device, the cable, and the
Switch’s functionality. Each port on the Switch has
auto-MDI function; you can make the connection using
crossover or straight through cable with uplink port or
regular port from the device.
Port Speed & Duplex Mode
After a connection is made, the Switch uses auto-negotiation to
determine the transmission mode for this twisted-pair
connection. If the attached device does not support autonegotiation or has auto-negotiation disabled; an auto-sensing
11
process is initiated to select the speed and set the duplex mode
to half-duplex.
