NOTES ON HANDLING INTERNAL HDD COMPONENTS

This unit has a built-in hard disk drive (HDD).

Be sure to observe the following points carefully when operating, setting-up and servicing the unit.

1. Do not subject the unit to shocks or vibration.

If the unit is subjected to shocks or vibration, it may

damage the HDD or cause corruption of the data stored in

the HDD.

• Do not move the unit while the power is turned on.

Always be sure to turn off the power before removing the

unit from or placing it onto the rack.

• When transporting the unit, pack it securely using the

specified packing materials. In addition, use a method of

transportation that minimizes vibration.

• When placing the unit down on a surface such as a floor,

attach the specified feet to the base of the unit and place

it down gently. If the feet are not attached, place the unit

down very carefully so that it does not make any noise.

2. Do not move the unit for 30 seconds after turning

off the power.

After the power is turned off, the disk inside the HDD will

continue to spin for a brief period due to inertia, and the

heads will be in an unstable state.

During this time, the unit is even more susceptible to

shocks and vibration than when power is being supplied.

Make sure that the unit is not subjected to even gentle

vibration for at least 30 seconds after turning off the

power.

3. Do not operate the unit when condensation has

formed.

If the unit is operated when condensation has formed, it

may cause operating problems.

If sudden changes in the ambient temperature occur, wait

for the temperature to stabilize before operating the unit.

4. Notes when replacing the HDD

Be sure to follow the correct replacement procedure when

replacing the HDD.

• HDDs that have been removed from their packaging may

not operate correctly if they are subjected to any shocks

or vibration. It is recommended that you place the HDD

onto a soft, level surface with the printed circuit board

facing upward after unpacking it.

• Be careful not to subject the HDD to shocks or vibration

when removing and tightening screws as part of the HDD

replacement procedure. Make sure that all screws are

tightened securely so that they will not become loose.

• The HDD is sensitive to static electricity, so you should

take proper precautions to prevent static electricity

buildup.

5. Handling the HDD unit by itself

If transporting or storing the HDD unit by itself, always be

sure to pack it in the specified packaging first.

In addition, use a method of transportation that minimizes

vibration.

If the HDD becomes damaged, handle the unit and the

damaged HDD that has been removed in order for it to be

replaced carefully to prevent the problem from being

aggravated until as the nature of the problem can be

checked and analyzed.
