Precautions for Safe Use
Anti-earthquake measures
Strong vibration such as that generated by an earthquake could cause the
equipment to move, fall, and be thrown out of the window, which results in serious
accidents. In order to prevent disastrous outcomes, consult a maintenance
company or an expert business for developing counter-seismic measures to
implement them accordingly.
Handling hard disks
A hard disk is a precision instrument. Handle it carefully when you use it.
Inappropriate handling could result in hard disk failure.
When carrying the system equipment or hard disk, handle it carefully not to

vibrate or hit it. Before handling a hard disk, remove static electricity or wear
cotton gloves.
Before moving the system equipment, turn off the power, remove the power

plug from the electrical outlet, and wait for at least 30 seconds.
Rat control
Rats can cause the following damage to a computer system:
Breakage of cable sheaths

Corrosion, contact failure, or soiled parts inside the equipment

In order to prevent the above damage, consult an expert business for developing
rat control measures and implement them accordingly.
Faulty disk
If you attempt to replace faulty disks using an incorrect procedure or faulty

alternative disk, data on the disk can be corrupted. Before replacing the
disk, back up the data.
Replacing a hard disk without failure would corrupt the data on it. Do not

remove any hard disk other than the faulty disk.
