Installation
• Since the HDD unit is 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.
• Even when the PS-A unit’s screen display disappears, the power
might be distributed inside (such as the “Standby” status etc). Be
sure to confirm that the power supply switch on the rear side of the
PS-A unit is OFF.
(1) Turn off the power switch of the PS-A
unit, remove the power cable. Put the
PS-A on the horizontal place while the
display side of it is downside.
(2) Unscrew the screws (2) from the
Expansion Board Cover, and remove
the Cover.
• When using the PCI
board, it is required to
remove the Expansion
Board Support first.
Then remove the
Expansion Board
Cover and the PCI
board.
