These instructions assume Windows 2000, Windows 98, or
Windows 95 is installed according to your computers
documentation. For the majority of applications, installing the

WA RNI NG High voltages inside the computer present a safety
hazard. Make sure the power is off before removing the cover. This
LAN adapter card is for use only with IBM or compatible UL-listed
personal computers that have installation instructions detailing
installation of PCI peripherals. Installation should be performed
with precautions to prevent damage to static-sensitive components.
Follow your computers instruction manual for specific
information on installing peripheral devices in your computer.
Once the adapter card is seated in a PCI slot and the computers
cover is back on, plug in the cable, turn on the power, and reboot
into Windows.
Important cable considerations: CopperThe AT-2450
F
TX is
for use with 10Base-T or 100Base-TX LAN segments, using an 8-
pin (4-pair) RJ45 connector for the network cable. Be sure that
all cabling used with the AT-2450TX in a 10Base-T segment is of
Category 3, 4, or 5, and that all cabling used in a 100Base-TX
segment is of Category 5.
Important cable considerations: FiberThe cable must comply
with the appropriate IEEE 802.3 standard for 62.5/125 µm multi-
mode fiber cable. The cable between the computer and the hub
must be less than 2000 meters long for full-duplex operation and
412 meters long for half-duplex operation. The transmit circuit
of the adapter card is connected to the receive circuit of the hub
and vice versa.

3 Install Drivers
Windows 2000 automatically installs and loads drivers into
memory with no reboot required. If you are using Windows 9x,
you may be prompted for the Windows 9x CD during the

Windows 2000 displays a Digital Signature Not Found dialog
box, click Yes to continue the installation.) Refer to the
Microsoft operating system documentation to configure network
clients and protocols.
InstallationWindows NT, Versions 3.5x and 4.0 /
