3.1 Installing optional units / expansion boards
A wide variety of optional units, DIM module, CF cards, manufactured by Digital Electronics Corporation
and commercial Expansion boards (PCI/ISA bus compatible board) can be used with the PL. When installing
those optional units, refer to the “Installation Guide” of each unit.
3.1.1 Uninstalling the Rear Maintenance Cover
Follow the steps given below when uninstalling the rear maintenance cover.
PL-6930/PL-7930 (4slot-type unit)
(1) Turn off the power and uninstall the power cable. Place the PL unit on a horizontal place as its screen
side could face to the bottom.
Be sure to confirm that power is not supplied to the PL unit before installing or removing
any optional units, DIM module, CF cards, or Expansion boards (PCI/ISA boards). Failure
to do so can result in an electric shock.
• Use a screwdriver to loosen and tighten the screws. Be sure not to tighten the
screws too much. Excessive force to the unit may cause damage.
• When removing or replacing screws, be careful that they do not fall inside the PL
unit's chassis.
• When the PL is in Soft OFF state, its screen looks “OFF” but some part of the
PL’s circuit still carries electricity. Make sure that no power cable has been
plugged to the PL unit at installation.
• The cover is made of aluminum so it is easy to bend or change its shape. Pay
special attention to the uninstalling operation.
• Make sure to remove the maintenance cover first, and then the half cover.
