Sun StorageTek 6540 Array Specifications
This chapter describes the physical, environmental, and electrical requirements for the Sun StorageTek 6540 Array. It contains the following sections:
The floor space at the installation site must be strong enough to support the combined weight of the cabinet, controller trays, expansion trays, and associated equipment. The site also requires sufficient space for installation, operation, and servicing the arrays and sufficient ventilation to provide a free flow of air to the unit.
The total weight of an expansion tray depends on the number of drives installed.
TABLE 3-1 provides the physical dimensions and weight of the array trays.
This section describes the environmental conditions that are prerequisite to installing the unit, and heat conditions that are generated by normal operation of the unit.
TABLE 3-2 lists the environmental conditions in which the module is designed to operate.
*If you plan to operate a system at an altitude between 3280 feet to 10,000 feet (1000 meters to 3048 meters) above sea level, lower the environmental temperature 3.3° F (1.7 °C) for every 3280 feet (1000 meters) above sea level.
TABLE 3-3 lists the nonoperating environmental conditions of the tray.
This section provides information regarding site power and wiring, module AC power requirements, and power cord routing instructions.
The tray uses wide-ranging redundant power supplies that automatically accommodate voltages to the AC power source. The power supplies operate within the range of 90 VAC to 264 VAC, at a minimum frequency of 50 Hz and a maximum frequency of 60 Hz. The power supplies meet standard voltage requirements for both domestic (inside USA) and international (outside USA) operation. They use standard industrial wiring with line-to-neutral or line-to-line power connections.
The AC power sources must provide the correct voltage, current, and frequency specified on the tray model and serial number label. The tray can run without interruption within the limits shown in TABLE 3-4.
The Sun Rack cabinet power distribution systems only work at 180 to 264VAC. Internal components will never be operated below 180V (200V nominal) when in this cabinet.
Power Cords and Receptacles
Power cords must be ordered separately so that are appropriate for use in a typical outlet in the destination country.
The power cords connect the power supplies in a tray to an independent external power source, such as those provided in the supported Sun cabinet, a wall receptacle, or uninterruptible power supply (UPS).
