Considerations for Installing the Card, Network Software,
and Drivers
Most of the network software manufacturers provide an
installation program that allows you to perform the entire
installation by making dialog-box choices. As part of the network
installation, the install script prompts for the adapter card driver
files. The driver files for the AT-2450 PCI Ethernet Adapter
Card are found on the Allied Telesyn CardAssistant diskette,
which you will be prompted to insert into a floppy drive.
Drivers for Workstations. Table 2 lists drivers for use in a PC
workstation.
Drivers for Servers. Table 3 shows the drivers for use in a server.

Installing the Card in a PCI Slot
Refer to your computer’s manual for specific information on
installing card-cage accessories in your computer.
WARNING
High voltages inside the computer present a safety hazard.
Make sure the power is OFF before removing the cover.
CAUTION
ThisLAN adapter cardisfor useonly withIBM orcompatible
UL-listed personal computers that have installation
instructions detailing installation of card-cage accessories.
Installation should be performed with precautions to prevent
damage to static-sensitive components.
NOTE
Windows 95 Installation: Skip ahead to Chapter 3,
“Installation with Windows 95” BEFORE plugging the card
into the computer. Resume here as indicated in the procedure
for installing software and drivers.
1. Make sure the computer’s power is turned OFF.
2. Pick the PCI card slot you wish to use. Follow the
manufacturer’s instructions for adding a card.

TIP: WheninstallingtheAT-2450FT,temporarilyremovethe
shields from the fiber-optics cable connectors to give the
connectors more clearance.
3. Attach the cable to the media port. Refer to Chapter 9,
Cabling, for information on media issues.
NOTE
In some mixed ISA/PCI PCs you must make sure the
AT-2450’s PCI slot has a unique interrupt request (IRQ)
number assigned. Allocation of interrupts is controlled by the
PCI computer’s Basic Input/Output System (BIOS). Usually
PCIIRQs are accessedthroughmenus of“CMOS Setup,”ISA
Configuration Utility (ICU), or “BIOS Setup” available when
booting the computer. See the PCI computer manual(s) for
setup access and instructions.
