Introduction
The DES-810 and DES-818 Fast Ethernet Switches are ideal for network
managers who want to boost workgroup performance easily by micro-
segmenting 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 brid ge high b andwidth
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 DES-
810 has eight 10Mbps twisted-pair ports and two 10/100Mbps N-Way
twisted-pair ports. The 10/100 Fast Ethernet Switch provides a store-and-
forward passing scheme. Filtering and forwarding rates for the switch ru n at
wire-speed, reducing latency within and across segments.
The 10/100 Fast Ethernet Switch provides an easy, affordable, high-
performance, seamless, and standard-based migration path to a 100BASE-TX

LAN while preserving your initial investment and use of 10Mbps Ethernet
LANs.
100Mbps Fast Ethernet Introduction
Computers today have beco me 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 straight-
forward 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
