Static Precautions
Static electricity can be a serious danger to the electronic components on this board. To avoid
damage caused by electrostatic discharge, observe the following precautions:
ü
Don’t remove the board from its anti-static packaging until you are ready to install it into
a computer case. Also, handle add-in cards and modules by the edges or mounting
bracket.
ü
Before you handle the board in any way, touch a grounded, anti-static surface, such as an
unpainted portion of the system chassis, for a few seconds to discharge any built-up static
electricity.
Before plugging the DC-390 series adapter into your system, make sure all jumpers on the
card are correctly set according to the instructions outlined in section 2.2. Also take care that
the
SCSI ID number
(0-6 for DC-390/390U; 0-15 for DC-390F/390U2B/390U2W) of each
SCSI device is set properly for the host adapter (Section 2.3).
The maximum devices that can be installed on each model are show below:

For DC-390F
, up to fifteen 16-bit and/or 8-bit SCSI single ended (SE) devices can be
connected. Up to seven of these can be 8-bit.
And only two of the three SCSI connectors,
either Internal or External, can be used to connect SCSI devices at any given time
.
•
For DC-390U2B,
mixing Fast/Ultra devices with Ultra2 devices brings the entire SCSI
bus to Ultra SCSI speed and cable requirements.
•
For DC-390U2W
, it is recommended that you keep your Ultra2 devices separate from
your non Ultra2 devices.
Mixing Ultra2 devices with non Ultra2 devices will bring the
Ultra2 devices to Ultra SCSI performance level
.
Correct
termination
and
cable connections
are also necessary for SCSI adapters to function
properly (Section 2.4 and 2.5).
