Introduction
The DES-810 and DES-818 Fast Ethernet Switches are ideal for network
managers who want to boost workgroup performance easily by microsegmenting a 10Mbps LAN while adding 100Mbps links. They are also
excellently suited to provide dedicated Fast Ethernet connections to key
network servers.
Each switch integrates 100Mbps Fast Ethernet with 10Mbps Ethernet
networks seamlessly. The speed migration design will bridge high bandwidth
Fast Ethernet network segments to traditional 10Mbps Ethernet network
segments quickly and simply.
The 10/100 Fast Ethernet Switch complies with IEEE802.3u, 100BASE-TX,
IEEE802.3 and 10BASE-T standards. The DES-818 model has 16 10Mbps
twisted-pair ports and two 10/100Mbps N-Way twisted-pair ports. The DES810 has eight 10Mbps twisted-pair ports and two 10/100Mbps N-Way
twisted-pair ports. The 10/100 Fast Ethernet Switch provides a store-andforward passing scheme. Filtering and forwarding rates for the switch run at
wire-speed, reducing latency within and across segments.
The 10/100 Fast Ethernet Switch provides an easy, affordable, highperformance, seamless, and standard-based migration path to a 100BASE-TX

LANs.
100Mbps Fast Ethernet Introduction
Computers today have become increasingly powerful, with the capability to
accommodate very sophisticated uses such as multimedia applications,
video-conferencing, and CAD/CAM. To utilize these technologically
advanced applications more efficiently, there is also a growing demand for
faster networks that can handle heavy network traffic.
Recognizing this need for greater bandwidth and lower latency, a variety of
technologies such as FDDI, ATM, and 100Mbps Fast Ethernet have been
adopted by many vendors. 100Mbps Fast Ethernet technology stands out as
the most inexpensive and smoothest migration path for existing 10Mbps
Ethernet users.
100Mbps Fast Ethernet is a relatively new 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 100Mbps Fast Ethernet is
compatible with all 10Mbps Ethernet environments, it provides a straightforward upgrade without wasting the company’s existing investment in
hardware, software, and trained personnel.
100BASE-TX Technology Overview
Cables and Connectors
Category 5 unshielded twisted-pair (UTP) cables are supported. UTP
category 5 cable uses the same RJ-45 connector used with 10BASE-T, wired

Overview
10/100 Fast Ethernet Switch User’s Guide
in the same configuration. Please note that the punch-down blocks in the
wiring closet must also be Category 5 certified. If these blocks do not meet
the standard, an upgrade is necessary.
Topology
A Fast Ethernet workgroup is configured in a star topology and is built
around a maximum of two repeaters. Each workgroup forms a separate LAN
(also known as a segment or collision domain), and these workgroups can be
easily interconnected through switches, bridges, or routers to form one LAN
large enough to encompass a high-rise building or campus environment.
Recent innovations in LAN hub technology such as stackable hubs, coupled
with the decreasing cost of switches, bridges, and routers, allow the design of
low-cost, efficient Fast Ethernet workgroups and enterprise LANs.
The following factors strongly influence the architecture of Fast Ethernet
networks:
•
The EIA/TIA 568 Wiring Standard imposes a 100 meter limit on
horizontal runs of twisted-pair cables; that is, connections from the
wiring closet to the end-station.
•
Fast Ethernet’s increased operational speed reduces the maximum
distance between all elements of the LAN (see below).
•
The EIA/TIA 568 Wiring Standard does not support the use of
coaxial cables for horizontal wiring.
Network
Network diameter, which is the distance between two end-stations in the
same collision domain, is the primary difference between traditional Ethernet
and Fast Ethernet. Due to the increased speed in Fast Ethernet and adherence
to the EIA/TIA 568 wiring rules, the network diameter of a Fast Ethernet
collision domain is limited to 205 meters; in contrast, the maximum
10BASE-T Ethernet collision domain diameter can be up to 2500 meters.
Overview
3
Hubs
Unlike 10BASE-T hubs which are all functionally identical, Fast Ethernet
hubs are divided into two distinct types: Class I and Class II. A Class I hub
repeats all incoming signals on one port to the other ports by first translating
them to digital signals and then retranslating them back to line signals. These
translations are necessary when connecting various network media to the
same collision domain, such as when combining two wire-pair 100BASE-TX
media with four wire-pair 100BASE-T4 media. Only one Class I hub can
exist within the same collision domain, thus this type of hub cannot be
cascaded. A Class II repeater, on the other hand, immediately repeats all
incoming line signals on one port to the other ports; no translations are
performed. This type of hub connects identical media to the same collision
domain; for example, TX to TX. At most, two Class II hubs can exist within
the same collision domain. The cable used to cascade these hubs is called an
inter-repeater link (IRL).
As mentioned earlier, stackable hubs can be used to increase the number of
available nodes in a collision domain. An entire hub stack counts as a single
repeater.
Connectivity Rules
•
The maximum length of a twisted-pair segment (that is, distance
between a port in the hub to a single-address network device such as
a PC, server, or LAN switch) is 100 meters.
•
The maximum diameter in a collision domain is about 205 meters
using two Class II hubs (or hub stacks) and 200 meters using one
Class I hub.
•
Between any two end-stations in a collision domain, there may be up
to three segments and two Class II hubs or two segments and one
Class I hub.

Overview
10/100 Fast Ethernet Switch User’s Guide
Switching Technology
Switching is fast becoming the industry standard for pushing the limits of
existing Ethernet networks. A switch bridges Ethernet packets between
Ethernet and Fast Ethernet LAN segments at the MAC address level of the
Ethernet protocol.
The difference between switched Ethernet (10Mbps, 100Mbps, or both) and
traditional Ethernet is analogous to the difference between a private phone
line and a party line. With switched Ethernet, each workgroup has a “private
line” so that transmitted packets don’t have to wait as long to gain access to
the network. When connected to a switched port, each Ethernet segment has
full “wire-speed” access, so a switch effectively divides a single Ethernet
LAN into bridged multiple LAN segments. Each segment can support a
workgroup or even provide a dedicated connection for a key workstation or
server. The result of dividing an Ethernet LAN into multiple segments is a
multiplication of internal bandwidth available to all stations on the LAN and
a reduction in latency rates during peak-use periods.
Benefits of Switching
Ethernet switching technology drastically increases the total bandwidth of a
LAN. It also provides configuration flexibility to local workgroups which
allows the network administrator to better control how network resources are
distributed against network load. Switching helps reduce the congestion
problems inherent in the contention-oriented CSMA/CD protocol, thereby
improving network response during high utilization periods.
Also, currently popular distributed client/server applications often require
higher bandwidth and tighter client-to-server integration. Legacy 10Mbps
Ethernet often is unable to provide a sufficiently sophisticated platform for
users to be able to take full advantage of such client/server applications.
Fast Ethernet switching not only satisfies both technical and business needs,
it also preserves the current investment in the huge 10BASE-T Ethernet

installed base. Compatibility with 10Mbps Ethernet ensures that users will
be able to migrate to Fast Ethernet at a pace appropriate to their installation
and needs.
10/100 Switching Technology
An integral extension of Fast Ethernet, 10/100 switching provides not
only a 100Mbps high-speed connection for carrying aggregated 10Mbps
traffic, it also handles the necessary conversion of MAC between
10BASE-T and 100BASE-TX. Combining Fast Ethernet and switching
technologies provides both bandwidth for local workgroups and a highspeed link to carry local traffic elsewhere in the network.

Ports
The product comes with twisted-pair ports. These ports can be used to
connect to individual stations in need of faster access, to segment heavily
utilized LANs, and/or to provide higher bandwidth access to a key server in a
client-server environment.
10Mbps Ports
The 10Mbps twisted-pair ports are standard RJ-45 connectors for use with
unshielded or shielded twisted-pair (UTP/STP) wiring. The 10Mbps ports
operate at an user-selectable speed of 10Mbps for half-duplex mode or
20Mbps for full-duplex mode. In either mode, the twisted-pair ports can
operate over 100 meters of Category 3, 4, or 5 UTP or STP cable.

10/100Mbps Ports
The 10/100Mbps twisted-pair ports are standard RJ-45 connectors for use
with unshielded or shielded twisted-pair (UTP/STP) wiring. These ports are
auto-negotiating between 10Mbps and 100Mbps, which means that they
detect the speed of devices connected to them and auto-configure to run at
that speed. The 10/100Mbps ports also operate in half-duplex mode or fullduplex mode at either speed. In either duplex mode, the twisted-pair ports
can operate over 100 meters of Category 5 UTP or STP cable.
Possible uses for the 10/100Mbps switch ports:
•
Add Fast Ethernet segments to an existing 10Mbps LAN.
•
Provide a dedicated Fast Ethernet connection for a shared LAN server in
a 10Mbps LAN.

Duplex Mode Switch
The 10/100 Fast Ethernet Switch supports full duplex operation on all 10 and
10/100 ports. When operating in full duplex mode, ports can transmit and
receive simultaneously. Each 10Mbps port must be manually set to the
proper duplex mode (half or full), but the switch can be set to auto-detect the
duplex mode for ports 1 and 2 (the two 10/100Mbps ports).
To change the duplex mode, change the Duplex Mode DIP switch setting on
the back of the 10/100 Fast Ethernet Switch. On the DIP switch, for ports 1
and 2, down is auto-detect, up is full-duplex. If port 1 or 2 is set to autodetect the duplex mode but is connected to a device that is unable to
broadcast its operational mode, the port will default to half-duplex operation.
For all other ports (3 - 10 or 3 - 18) up is full duplex, down is half duplex,
and the switch numbers correspond with the port numbers. It is not
necessary to turn off the device when changing the duplex mode setting. For
more information, see “Setting the Duplex Mode” in the next chapter.
Note:
12
Full-duplex mode can only be used for
connections to other switches or to network
stations. Connections to hubs must use halfduplex mode only.

Switch. When connecting a workstation or a server running at 100Mbps, a
standard 100BASE-TX adapter must be installed. When running at 10Mbps,
ports 1 and 2 are functionally identical to the 10Mbps ports described below.
10Mbps Ports
These ports require Category 3, 4, or 5 unshielded twisted-pair or shielded
twisted-pair (UTP/STP) cable. They can be used to connect to individual
workstations, servers or other 10BASE-T devices. The attached station must
be within 100 meters of the 10/100 Fast Ethernet Switch. When connecting a
workstation or a server, a standard 10BASE-T adapter must be installed.
Cable Types
Under most conditions, the ports on the 10/100 Fast Ethernet Switch may use
normal straight-through cables. Some circumstances, however, may require
the use of crossover cables (i.e., cables in which the twisted-pair outputs have
been crossed). See Appendix B for more information on crossover cable
pinouts. The table below describes when to use which cable type.

Setting the Duplex Mode
Each port of the device can be set for half-duplex or full-duplex operation.
The two 10/100Mbps ports can be set to either full-duplex or auto-detect
duplex mode. At half-duplex operation, packet transmission and reception
do not occur simultaneously, thus communication speed is limited to
100Mbps using 100BASE-TX mode and 10Mbps using 10BASE-T mode. At
full-duplex operation, packet transmission and reception occur
simultaneously, thus communication speed is doubled to 200Mbps using
100BASE-TX mode and 20Mbps using 10BASE-T mode. Full-duplex
operation can be used on links between the 10/100 Fast Ethernet Switch and
any device (or station) that supports full-duplex operation.
Set the duplex mode through the duplex mode switch at the rear of the
device. To set a port to full-duplex operation, slide the corresponding duplex

switch up. To set for half-duplex, set the duplex switch down. To set either
or both ports 1 and 2 to auto duplex mode detect, set the corresponding
switch down.
Figure 6 Setting the Duplex Mode
Note:
Full-duplex mode can only be used for
connections to other switches, network
servers, or network stations.
Connections to hubs must use half-duplex
mode only.

LAN Microsegmentation
Perhaps the principal purpose for the 10/100 Fast Ethernet Switch is to
microsegment an existing LAN to improve network latency rates and
increase overall performance. The 100Mbps ports on the switch can be used
to connect those segments which require greater throughput.

Fast Ethernet Server Connection
The 10/100 Fast Ethernet Switch is an ideal device for connecting a
dedicated server via a 100Mbps line to a 10Mbps network. Increasing the
bandwidth speed of a server connection can provide significant
improvements in network performance.
