Caution for Handling the Unit with Built-in HDDs (for Part 2)
This unit has two built-in hard disk drives (HDDs). Pay careful attention to the followings and perform
operations with extra care when installing, servicing, and maintaining this unit.
Never give any mechanical shock and vibration
This may cause an HDD trouble or destroy the data in HDD.
. Pack this unit using the specified packing materials when carrying the unit. Use a cart with less-
vibration when carrying this unit by a cart. If an excessive mechanical shock and vibration are applied,
the HDD may be damaged.
. Never move this unit under power-on state. Take out or insert this unit from or into the rack in a state of
powering off. Also never install or remove the cabinet under power-on state.
. When putting the unit on the floor, put this unit gently with the four specified feet which is attached to
the bottom of the unit on the floor. If there are no feet on the bottom, attach them before putting this
unit, or put this unit gently so that no sound is generated.
Never operate the unit for 30 seconds after the power is turned off
The disks in HDD rotate by inertia for a while after the power is turned off. In this case, the heads are in
the unstable state. During this period, the HDD is more sensitive to a mechanical shock and vibration than
during power on state. Never give even a slight shock at least 30 seconds after the power is turned off.
Operations can be initiated (because the disks stop) after 30 seconds or more.
In the event of trouble in HDD
If there is something wrong with the HDD of this unit (a failure occurs in the HDD), handle this unit in
the same manner as described above. This protects the HDD from increase of the damage till confirming
the contents of the failure or analyzing the failure.
Pay careful attention to the following when handlings the HDD alone.
Notes when carrying or keeping the HDD
