7.3 Periodic inspection items
CAUTION
Do not disassemble the unit during inspection or cleaning. The unit has a sealed structure and does not require internal
inspection or cleaning. When the cover is removed, do not touch internal parts, as doing so might cause a burn injury,
damage to internal parts, or unit failure.
NOTICE
• Do not hot swap USB equipment or cables with the unit. Hot swapping might cause the unit to malfunction or
stop.
• Before moving the unit, shut down the OS, turn off the MAIN POWER switch, and then remove the power cable
plug from the outlet. Not following this procedure might result in unit failure.
• When carrying or transporting the unit, it is recommended that you use the packing materials in which the unit
was packaged for delivery. If such packing materials are not available or are damaged, carefully pack the unit in a
way that protects it from shock, vibration, and electrostatic discharges.
• Moving or transporting a unit that is installed in a cubicle or rack with casters might subject it to excessive
vibration or physical impact, resulting in failure of the unit. Select or design a cubicle or rack that meets the
installation conditions. Similarly, make sure that the unit is not subject to vibration or physical impact when you
move, carry, or transport it.
• Table 7‒5: Periodic inspection items shows periodic inspection items. Hitachi is responsible for performing
periodic inspection under maintenance contract. Only Hitachi staff and officially-trained personnel are permitted
to perform periodic inspection.
Include the inspection in the system operation schedule.
