Installation
• Shock Danger! Be sure to unplug the
PS-A unit from its power supply prior to
installing the HDD unit.
• Since the HDD unit and PS-A's the cir-
cuit board are a precision instrument
that has a low resistance to shocks, be
sure it is neither hit by nor pressed
strongly against another object when
installing it.
• The electric power may be supplied to
the PS-A unit even when the screen
blacks out (such as the standby
mode). Be sure to confirm that the
power cable on the rear side of the
PS-A is disconnected.
When attaching the HDD unit
to the PS-3650A
(1) Turn OFF the power switch of the PS-A
and remove the power cable. Place the
PS-A on a flat, level surface facing the
display face downwards.
(2) Unscrew the expansion board cover's
screws (2) and remove the expansion
board cover.
(3) Unscrew the expansion board base's
screws (4) and remove the expansion
board base.
(4) Remove the DISK cover.
(5) Mount the HDD unit vertically on the
circuit board and plug the HDD unit
cable connector in the Serial ATA
interface.
• Mount the HDD unit vertically and
thoroughly not to hit the circuit board.
Otherwise, it may cause a malfunction
or damage the HDD unit and PS-A.
(6) Fix the HDD unit with the screws (4)
which are contained in your package.
