Installing the AHA-2940/2940W
Follow these instructions to install the AHA-2940/
2940W:
1
Turn
OFF
power to the computer and peripheral
devices and disconnect the power cords.
2
Remove the cover from the computer case.
3
Locate an unused 32-bit PCI expansion slot (the
slot must support Bus Master data transfers);
unscrew and remove the metal bracket that covers
the card-slot opening. (Save the screw to use when
securing the host adapter in your computer.)
PCI slots are shorter than ISA or EISA slots and
are typically white. Usually there are three PCI
slots. (One of these may be a shared slot into
which you can insert either an ISA/EISA board or
a PCI board.)
4
Insert the AHA-2940/2940W in the PCI expansion
slot. Press it down firmly so that the contacts are
securely seated in the slot.
5
When the AHA-2940/2940W is firmly seated in
the expansion slot, secure the metal bracket of the
host adapter with the screw you removed in step 3.
Do not replace the computer cover or reconnect your
computer and peripherals to their power sources yet!
SCSI Configuration Guidelines
Before installing your SCSI devices, you should
understand the basic SCSI concepts described in this
section. The information will help you set up your
host adapter and devices so they function properly.
SCSI ID Numbers
Each device attached to the AHA-2940/2940W, as
well as the AHA-2940/2940W itself, must have a
unique SCSI ID number (0 to 7 for the AHA-2940,
and 0 to 15 for the AHA-2940W).
We recommend that you leave the AHA-2940/
2940W set to its default setting of SCSI ID 7. If you
need to change the AHA-2940/2940W SCSI ID, see
