Getting Started
This document contains information about installing and
configuring the AdaptecPCI Ethernet and Fast Ethernet network
interface cards (NIC’s).
The following describes the sections in this document:
Part 1, Installing NIC’s, describes how to install your
Adaptec NIC.
Part 2, Installing LAN Drivers, describes how to install and
configure LAN drivers on various operating systems.
Part 3, Installing Duralink Failover Drivers, describes how
Duralink Failover works and adds value to your network. It
gives instructions for installing Duralink Failover drivers for
Windows NT-based servers and NetWare-based servers.

Fast Ethernet Network Interface Cards
Fast Ethernet
Fast Ethernet is a networking standard defined by the Institute of
Electrical and Electronic Engineers (IEEE) in their IEEE 802.3u
Specification. Fast Ethernet runs at 100 Mbps or at 200 Mbps in Full
Duplex mode.
Fast Ethernet uses the same Carrier Sense Multiple Access with
Collision Detection (CSMA/CD) architecture used on 10BASE-T
and 10BASE-2 10 Mbps network specifications, which allows for
easy integration with existing networks.
Duralink Failover
Duralink™Failover provides protection from system failures on Fast
Ethernet servers running mission-critical applications. During a port
failure, Duralink Failover keeps the connection to the server
established by moving all traffic on the affected segment to a
standby Network Interface Card (NIC) or port. When a failure is
detected on the primary port, that port is disabled and a secondary
port takes over to carry the load, and keeps the network running
without interruption.
This Failover operation occurs when any of the following conditions
exist:
■There is a link loss
■A watchdog timer expires
■An abnormal hardware interrupt occurs
■Abnormal Send/Receive counters, such as too many collisions
or errors, occur on the segment
Supported Platforms and NICs
Duralink Failover is supported for Windows NT™and Novell
Netware-based servers.
Duralink Failover is compatible with Adaptec ANA™-6911A single
port NIC, ANA-6922A dual port NIC, and ANA-6944A quad port
NIC.

Getting Started
Adaptec NICs
The Adaptec PCI Ethernet and Fast Ethernet NICs currently
includes the following products:
■10/100 AutoSensing NICs - support autosensing between 10
and 100 Mbps line speeds. The NICs support universal cable
connectivity with RJ-45 and BNC connectors. They support
Duralink Failover protection.
■Duo NICs - offers two high-performance Ethernet/Fast
Ethernet ports on a single NIC. Each port runs at independent
speeds for maximum flexibility. The NICs support Full Duplex
to deliver speeds up to 400 Mbps cumulative throughput. They
support Duralink Failover protection.
ANA-6911A
Single RJ-45 Port
ANA-6922
Port 1
Port 2

1-4
Fast Ethernet Network Interface Cards
■Quartet NICs - provide four separate Fast Ethernet ports on a
single NIC. Each port runs at independent speeds for
maximum flexibility. The NICs support Full Duplex on UTP
for up to 800 Mbps throughput on one NIC. They support
Duralink Failover protection.
■Fiber Optic NICs - support Multimode Fiber (MMF) and
cabling distances from 400 meters to 2 kilometers. They are
available with SC (push on) or ST (twist on) connectors. The
NICs support Full Duplex for speeds of up to 200 Mbps
cumulative throughput.

chip
EMDIAG program MS-DOS 3.3 or later
Bold Used for keystrokes (press the Enter key) and for
options you are directed to select from a menu or
list (select Configuration Status from the main
menu).
Helvetica Used for operator entry that you must type
exactly as shown (a:\emdiag) and for messages
that appear on the screen (Performing Automatic
Media Detection).
Helvetica Italics Used as a place holder for text you must
determine and type (
drive = boot drive letter) and
for program and file names that appear in body
text (the
readme.txt file).
