The appliance has two power modules that provide redundancy. When selecting
the installation site of the appliance and storage shelves, consider the following:
See "Power supply overview" on page 17.
See "Heat dissipation" on page 18.
See "Environmental checklist" on page 19.
Use the following best practices to ensure that your environment has the correct
electrical setup.
Verify proper grounding for the main AC power supply.
■
Overcurrent and overload protection must be available for the entire system.
■
The circuits and the associated circuit breakers must provide enough power
■
and overload protection.
Separate the power supply from other large distribution loads or engines to
■
prevent possible damage to the appliance. Examples of systems that have a
large power draw include air-conditioners, elevators, or factory machines.
See "Power supply overview" on page 17.
This section describes heat dissipation requirements of the appliance and the
storage shelf. Before installing the devices, check whether the heat dissipation on
site satisfies the conditions for proper running of the device. For optimal
maintenance, ventilation, and heat dissipation, pay attention to the following when
installing the appliance and the storage shelf into the rack cabinet.
For proper ventilation, the rack cabinet should be at least 100 cm (4 ft) away
■
from surrounding walls and at least 120 cm (4 ft) away from any other cabinet(s).
