Safety guidelines
Hitachi AMS 2000 Family Storage System Service Guide
Equipment safety
The following safety instructions are designed to help protect the array from
various types of physical and electrical damage.
• Moisture. Do not store, install, or use the array in a place where
moisture exists or is likely to condense on the unit.
• Heat. Do not install the unit in a rack which has less than the specified
cooling. The AMS 2100/2300 has heat sensors which will cause the unit
to shut down if the internal temperature exceeds the specifications. See
the Hitachi AMS 2100/2300 Reference Guide for details.
• Electromagnetic Interference. When the array is operating under
normal conditions, close the rack doors if the rack has them. This helps
protect the array from electromagnetic interference.
• Do not perform any operations on the array other than those in this
guide because unexpected failures or accidents may occur.
• Use only the power cords provided with the array because unexpected
accidents or failures may occur.
• Shut off the array’s power if smoke, abnormal heat generation, or an
unusual odor occurs. Ignoring these conditions may cause an electrical
shock, damage to the equipment, or fire.
• Avoid using the equipment for any use other than its original purpose.
• Do not put heavy material on the equipment because it can fall and
injure you, or the subsystem may not operate normally.
• The array is provided with ventilating holes on external covers in order
to prevent overheating. Therefore, be sure to leave at least 2 inches (5
cm) in front and rear of the array and not block the ventilation holes.
Otherwise, the array may overheat and fail.
• Use specified optional parts, cables, and connectors. Otherwise, a fire
or a failure of the array may be caused as well as the deterioration of
the performance.
• Do not put containers that contain any type of liquids or metal articles
on top of the array. If they spill and accidentally get into the array, they
can cause a fire, an electric shock, or an array failure.
• When a failure occurs in the unit, refer to this manual and to the Hitachi
Hitachi AMS 2100/2300 Storage System Hardware Guide to prevent
personal injury. If the failure does not correspond to any corrective
measure written in this manual, inform the maintenance engineer.
CAUTION! Electrostatic-sensitive. Ground yourself before touching.
To avoid damage to the array or array components due to electrostatic
discharge (ESD), wear an anti-static wrist strap when handling, installing,
or removing any components from the array. Connect the clip on the wrist
strap to an unpainted part of the array chassis frame to safely channel any
static electricity generated by your body to ground. If no wrist strap is
available, ground yourself by touching an unpainted part of the array
chassis frame.
