Installing Optional Hardware
The following optional units can be installed to the 9000Pro.
Before installing the optional hardware, make sure you have a Philips screwdriver.
Installation Precautions
● Plug-in Boards ● Hard disk unit ● SIMM
SIMM cover
Plug-in board/Hard disk cover
WARNING
• Before beginning installation, switch off the power to the 9000Pro and connected peripherals, and unplug them from the
power outlet. Then remove all cables connecting the 9000Pro to other devices. (Leaving the power cord connected while
working can result in electric shock. Leaving other cables connected can interfere with work.)
• Be careful not to drop any screws inside the instrument during installation (this can be prevented by keeping the Plug-in
Board, hard disk unit and cover away from the instrument while attaching). If this does happen, be sure to remove the
screw(s) from inside the unit before turning the power on. Loose screws inside the instrument can cause improper opera-
tion or serious damage. If you are unable to retrieve a dropped screw, consult your Yamaha dealer for advice.
• Install the Plug-in boards, the hard disk unit, and the SIMM modules carefully as described in the procedure below.
Improper installation can cause shorts which may result in irreparable damage and pose a fire haz-ard.
• Do not disassemble, modify, or apply excessive force to board areas and connectors on Plug-in boards/hard disk/SIMMs.
Bending or tampering with boards and connectors may lead to electric shock, fire, or equipment failures.
CAUTION
• Before handling the Plug-in boards/hard disk unit /SIMMs, you should briefly touch the metal surface to which the Plug-in
board/hard disk or SIMM cover is attached (or other such metallic area — be careful of any sharp edges) with your bare
hand so as to drain off any static charge from your body. Note that even a slight amount of electrostatic discharge may
cause damage to these components.
• It is recommended that you wear gloves to protect your hands from metallic projections on the Plug-in boards, Hard disk
unit, SIMMs, and other components. Touching leads or connectors with bare hands may cause finger cuts, and may also
result in poor electrical contact or electrostatic damage.
• Handle the Plug-in boards/Hard disk unit/SIMM with care. Dropping or subjecting them to any kind of shock may cause
damage or result in a malfunction.
• Be careful of static electricity. There are times when static electricity affects the IC chips on the Plug-in board. Before you
lift the optional Plug-in board, to reduce the possibility of static electricity, touch the metal parts other than the painted area
or a ground wire on the devices that are grounded.
• Do not touch the exposed metal parts in the circuit board. Touching these parts may result in a faulty contact.
• When moving a cable, be careful not to let it catch on the circuit Plug-in board. Forcing the cable in anyway may cut the
cable, cause damage, or result in a malfunction.
• Be careful not to misplace any of the screws since all of them are used.
• Do not use any screws other than what are installed on the instrument.
