3
Remove the corresponding expansion slot cover
from the PC chassis.
4
Align the bus connector on the bottom of the host
adapter with the VL-Bus slot and carefully press
it down into the slot. Secure the host adapter
bracket to the PC chassis with the screw from the
removed expansion slot cover.
Note:
reconnect the power yet!

Connecting SCSI Peripheral Devices
Caution:
only single-ended SCSI devices. Do not con-
nect differential SCSI devices to this host
adapter. Read the documentation to deter-
mine whether a device supports single-
ended or differential SCSI.
Connecting Cables
SCSI devices are cabled together in a single, con-
nected series called the SCSI bus. SCSI cables must
run sequentially from one device to the next, with no
branching.
1
Lay out the cables and find the pin-1 element of
each cable and peripheral connector.
On internal cables, pin 1 is usually marked with a
contrasting color on one edge of the ribbon cable,
and a small triangle marks pin 1 on the SCSI con-
nector. External cables can only be plugged in one
way, so pin-1 orientation is automatic.
2
Attach the SCSI cable(s) to the host adapter and
the peripheral device(s), using the internal and/
or external connector(s).
Be sure to maintain correct pin-1 orientation
throughout the bus. The AVA-2825 uses a 50-pin
high-density external connector, and a 50-pin flat
ribbon-type internal connector.
Do not replace the chassis cover or
AVA-2825 host adapters support
