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.
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.
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.
