Caution for Handling the Unit with Built-in HDD (for Part 1)
This unit has two built-in hard disk drives (HDDs). Pay careful attention to the following and perform
operations with 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.

when carrying this unit by a cart. If an excessive mechanical shock and vibration are applied, the HDD
may be damaged.

power off. Also never install or remove the cabinet under power on state.

the bottom of the unit. If there are no feet on the bottom, attach them before putting this unit, or put
