Ensure that the rack is at least 100 cm (approximately 3 feet) away from the
■
walls.
Ensure that the clearance between any racks is at least 120 cm (approximately
■
4 feet) for maintenance, adequate ventilation, and effective heat dissipation.
Data centers with two foot spaces in the front and in the back of the appliances
are acceptable with proper cooling and ventilation.
Ensure that other equipment does not prevent air transfer between the cabinet
■
and the room. Adequate distance is necessary for cooling of the devices.
The appliance and the 3U16 storage shelf each have two power modules, which
connect to the main AC power source. Both modules, on both devices, provide
redundant power in case of failure.
Two power cords are provided for each device. Connect each power cord to an
independent AC power source.
Caution: If multiple appliances are to be installed on site, check whether the power
distribution in your equipment room satisfies the power requirements. You should
include the maximum input power and the quantity of devices in your planning.
