3.2 Peripheral Devices Installation
A wide variety of optional units, DIM module, CF cards, manufactured by Pro-face and commercial
Expansion boards (PCI bus compatible board) can be used with the PS-A.
When installing the optional units, refer to each unit's “Installation Guide”.
3.2.1 Main Memory Installation
(1) For PS-3450A Series, unscrew the screws (2) from the Expansion Board Cover in advance, and remove
the cover. For PS-3451A Series users, please go to Step (2).
Be sure to confirm that power is not supplied to the PS-A unit before installing or removing
any optional units, DIM module, CF cards, or Expansion boards (PCI boards). Failure to do
so can result in an electric shock.
• If the PS-A unit is in the Soft OFF Status, power is supplied to a part of circuits
even when no screen is displayed. Be sure to confirm that a power cable is not
connected before installing or removing peripheral equipment.
• Use a screwdriver to loosen or tighten the screws. Be sure not to tighten screws
too tightly, since it may damage the unit.
• When removing or replacing screws, be careful that they do not fall inside the PS-
A unit's chassis.
• When installing the PS-A unit, or when attaching an optional item to the PS-A
unit, do not hold the PS-A unit's rear-face fan cover while performing the work.
Doing so may damage the fan cover or cause the cover to fall off.
