CAUTION! Ensure that the rack in which the units are mounted is
electrically configured with two AC circuits and that the power
supplies for each base and expansion unit are connected to
separate circuits. This prevents unit failure in case one of the
power circuits fails.
Floor load rating
Before installing the base and expansion units in a rack, check the load-
bearing specifications of the floor where you are placing the rack(s). To
assure adequate load-bearing capacity, plan for the maximum
configuration. See
calculating the floor loading. Please refer to the AMS 2000 Family Site
Preparation Guide, MK-98DF8149EN for information about the array and
rack weights.
Installation area and service clearance
Please see the information and specifications in the Hitachi AMS 2100/2300
Site Preparation Guide before installing an AMS 2100/2300 storage system.
•
Installation area means a large enough area to assure the intake and
exhaust air.
•
Service clearance means an area required to maintain the Hitachi AMS
2100/2300. Be sure to install the equipment in a place to avoid
problems such as the inability to open the rack door completely or
inadequate ventilation.
Notes about installation
•
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) of space at the front and rear of the array so the ventilation holes
are not blocked. Otherwise the array may overheat and fail.
•
The direction of airflow is front/input to rear/output on the RK base
controller tray and all RKAK/RKAKX drive trays.
•
Hitachi Full-Height Solutions racks have a front door. AMS 2000 Family
racks have no door in the front, but have a ventilated door in the back
that allows the system to draw air through the front and exhaust air
through the back. Do not block the front of mounted components or the
rear-ventilated door.
•
Use specified optional parts, cables, and connectors. Incorrect parts
can cause a fire, personal injury, array failure, and/or reduced
performance.
•
If you detect an abnormal odor such as a something burning, unusual
heat, or see smoke, turn off the power to the array from the
distribution panel immediately and contact your service personnel.
•
Do not put anything heavy on top of an array. Otherwise, the array may
fall and cause personal injury.
•
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.
