Introduction
This installation guide explains how to install and use your AHA-F940 and
AHA-F950 Fibre Channel host adapters. TheAHA-F940 is a 32-bit PCI-to-
Fibre Channel adapter; and the AHA-F950 is a 64-bit PCI-to-Fibre Channel
adapter. In this installation guide, the two adapters are collectively referred to
as the AHA-F940/F950.

Installation and Setup
Installing the Adapter
WARNING: Turn OFF power to the computer and
disconnect the power cord.
1Remove the cover from the computer case. (refer to the
instructions in your computer documentation.)
2If you are installing the AHA-F940, locate an unused 32-bit
PCI expansion slot; if you are installing the AHA-F950,
locate an unused 64-bit PCI expansion slot. PCI slots are
typically white or ivory. Unscrew and remove the expan-
sion slot bracket that covers the card-slot opening.
3Insert the host adapter in the slot; press it down firmly so
that the bus contacts are securely seated in the slot. Secure
the host adapter bracket with the screw you removed in
Step 2.
4Replace your computer cover and connect all power
cables; turn on your computer.
If your CMOS setup requires you to enable PCI bus parame-
ters, do so now. Refer to your computer’s documentation and
also Troubleshooting Checklist on page 4.

Connecting Cables
To connect devices to the AHA-F940/F950, obtain the appro-
priate cables, as described below. (See also Fibre Channel
Topologies on page 4 for typical configurations.)
DB-9 Copper Interface Connector
You can use one of two types of cables to connect to the DB-9
copper interface connector on the AHA-F940/F950.
nIntra-cabinet cables are used to route signals within a cabi-
net, such as backplanes or disk arrays.
nInter-cabinet cables are for point-to-point and fabric
(cross-point switch) topologies.
Media Interface Adapter (MIA)
An MIA can be installed at the DB-9 connector on the adapter
to convert copper electrical signals into optical signals to allow
for data transfer over extended distances.
The cable used to connect to the MIA consists of two small
joined strands with a pair of standard Duplex SC fiber optic
connectors at each end.
Installing Drivers
AIC-1160 Drivers must be installed to your system. Refer to
the instructions for your operating system in the Adaptec 1160
Family Management Set User’s Guide to correctly install driv-
ers. The 1160 Family Manager Set works with the following
operating systems:
nNovell NetWare
nSun Solaris
nMicrosoft Windows NT
nSCO UnixWare
Congratulations!Installation of your host adapter is
complete. For helpful information on using your host adapter,
refer to Using Your Fibre Channel Adapter.

Using Your Fibre
Channel Adapter
Fibre Channel Topologies
Fibre Channel-Arbitrated Loop
The Fibre Channel-Arbitrated Loop (FC-AL) topology allows
you to attach up to 127 nodes without hubs and switches. FC-AL
is a time-shared, full-bandwidth, distributed topology where
each port includes the minimum necessary connection function.
Workstations or servers can be connected to a single disk or a
disk loop with either optical fibre or copper media depending on
the distance requirement. The following figure shows an exam-
ple of this configuration.
Note: Disk drives connected in this configuration
must have an FC-AL interface.
Point-to-Point
The Point-to-Point topology uses Fibre Channel, without the
loop overhead, to increase performance and simplify cabling
between a RAID storage box and a host or multiple hosts. The
following figure shows an example of this configuration.
Troubleshooting Checklist
If you have problems using your host adapter, check these
items first.
nAre all devices powered?
nAre all cables properly connected?
nIs the host adapter firmly seated and secured in the PCI bus
slot?
nDoes your system CMOS setup require you to enable PCI
bus parameters? If so, refer to your computer’s documenta-
tion for instructions. Check that IRQ channel assignment,
board, and BIOS settings have been made.
nSome configuration options apply to a specific PCI bus
slot, so if you change these options be sure you are apply-
ing them to the slot in which the host adapter is installed.
Check your computer documentation to verify which slot
corresponds to which number.
–If there is an interrupt type or interrupt line option in
the setup program, be sure to select Int-A or Interrupt
Type = A. Depending on your system design, you may
also be required to change a motherboard jumper set-
ting.
–If there is a triggering interrupt option, be sure to select
Level.
–If there is an option to enable or disable bus mastering
for the PCI slots, be sure to select Enabled.
–If there is an option to enable or disable individual PCI
slots, be sure the slot in which you install the host
adapter is Enabled.
–If your computer has a combination of ISA (or EISA)
boards and PCI boards, you may need to mark the
IRQs used by ISA/EISA boards as used so the system
BIOS will not try to assign these IRQs to other PCI
boards.
–In some systems the BIOS reserves a set of available
IRQs for PCI boards, and you have to assign these
IRQs manually.
