Shipping and storage requirements
NOTE:
Systems and components must not experience changes in temperature and humidity that are likely to cause
condensation to form on or in that system or component. Do not exceed the shipping and storage temperature gradient of
45°F/hr (25°C/hr).
Table 1. Shipping and storage requirements
Requirement
Description
Ambient temperature
50° F to 95°F (10°C to 35°C)
Temperature gradient
77°F/hr (25°C/hr)
Relative humidity
20% to 80% noncondensing
Elevation
0 to 10,000 ft (0 to 3,048 m), operation
is derated 1.1°C/1,000 feet (305 m) above
7,500 feet (2,286 m)
Power requirements
The input current, power (VA), and dissipation per enclosure listed in this document are based on measurements of fully
configured enclosures under worst-case operating conditions. Use the operating maximum values to plan the configuration of
your storage system. These values represent either:
●
values for a single power supply line cord, or
●
the sum of the values shared by the line cords of the combined power supplies in the same enclosure, with the division
between the line cords and supplies at the current sharing ratio (approximately 50% each).
A power and weight calculator is available at https://powercalculator.emc.com. Use this calculator to refine the power and heat
values to more-closely match the hardware configuration for your system.
A failure of one of the combined power supplies per enclosure results in the remaining power supply supporting the full load. You
must use a rackmount cabinet or rack with appropriate power distribution, and have main branch AC distribution that can handle
these values for each enclosure in the cabinet.
