Chapter 1: Network Adapter Card Overview
14
Overview
The Allied Telesyn Ethernet network adapter cards are designed to
simplify the task of building a new 10 Mbps or 100 Mbps Ethernet network
or expanding an existing one. Offered in a variety of port configurations,
these adapters give you the power and flexibility to build an Ethernet
network suited to the unique requirements of your business environment.
Table 1 lists the port configurations of the network adapter card series
described in this guide.
Note
The AT-2450FTX, AT-2700FX, AT-2700FTX, and AT-2745FX Series
are no longer available from Allied Telesyn. They have been
replaced by the AT-2451FTX, AT-2701FX, AT-2701FTX, and
AT-2746FX Series, respectively. They are described in this guide for
reference purposes for those networks where the cards are already
installed.
As shown in Table 1, most of the network adapter cards discussed in this
manual are dual port adapters. A dual port card has either a twisted pair
port and a fiber optic port or two fiber optic ports.
Dual port adapters can simplify the installation and maintenance of your
network because the same network adapter card can be used for either
twisted pair cable or fiber optic cable. This eliminates the need of
purchasing different cards for different cable media and so reduces the
number of types of adapters needed to build your network.
