and their host adapter work together, and they are referred to as a SCSI
bus.
Each SCSI host adapter that you install can act as host for up to 15
peripheral devices (depending on the SCSI bus speed), not including the
adapter itself.
2.2.2 Selecting a PCI Slot
For safe and proper installation, check the user’s manual supplied with
your computer and perform the following steps.
Step 1.
Ground yourself
before removing this host adapter board.
Step 2.
Remove the SYM22902 from its packing and verify it is not
damaged.

.
A more detailed drawing is located in
Figure A.1.
Step 3.
Switch off and unplug the system.
Step 4.
Remove the cabinet cover on your computer to access the PCI
slots.
Caution:
Ground yourself
by touching a metal surface before
handling boards. Static charges on your body can damage
electronic components. Handle plug-in boards by the edge;
do not touch board components or gold connector contacts.
The use of a static ground strap is recommended.
Step 5.
Locate the PCI slots on your computer.
A 32-bit slot may be used but full performance requires a 64-bit
slot. Refer to the user’s manual supplied with your computer to
confirm the location of the PCI slots. Also, the SYM22902
requires a PCI slot that allows bus master operation.
