Be sure you have a Phillips screwdriver before you attempt to
remove the system unit cover or install options. You may also
need a flat-head screwdriver to remove some of the cables from
the back of the system unit.
There are two methods of adding internal options:
• Add the options yourself.
• Have a Digital service representative add them.
If you choose to add options yourself, note that additions
typically take about 15 minutes for each option, although some
procedures may take more or less time.
Improper installation of an optional drive or module could lead
to damage and failure of both the new drive or module and other
system components. Your DEC 3000 Model 300 Series AXP
warranty may not cover such a failure.
Be sure to refer to the operating system software product
description (SPD) to verify that all installed devices are
compatible with the operating system you are using.
