Dimension and Weight Specifications

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.

TABLE 3-1 Tray Dimensions and Weight
Height	Width	Depth	Weight (Fully Populated)
Controller tray
6.87 in.	17.5 in.	24 in.	80.5 lbs
17.45 cm	44.45 cm	60.96 cm	36.51 kg
Expansion tray
5.25 in.	17.5 in.	24 in.	95 lbs
13.335 cm	44.45 cm	60.96 cm	43 kg

Environmental Requirements

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.

TABLE 3-2 Operating Environmental Conditions
Condition	Range
Temperature	32^° F to 104^° F (0^° C to 40^° C)
Relative humidity	20% to 80% noncondensing
Altitude*	100 feet (30.5 meters) below sea level to 10,000 feet (3,048 meters) above sea level
Shock	25 G at 3.75 ms triangular
Vibration	0.25 G, 5 to 150 Hz sinusoidal
Heat output Controller Tray Expansion Tray	235 watts avgerage (804 BTU/Hr) 444 watts average (1517 BTU/Hr)

*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 shows the operating temperature, relative humidity, altitude, shock, vibration, and heat output ranges of the array trays.

TABLE 3-3 lists the nonoperating environmental conditions of the tray.

TABLE 3-3 Nonoperating Environmental Conditions
Condition	Range
Temperature (storage)	14^° F to 149^° F (-10^° C to 65^° C)
Temperature (transit)	-40^° F to 149^° F (-40^° C to 65^° C)
Humidity (storage)	10% to 93%
Humidity (transit)	5% to 95%
Altitude	100 feet (30.5 meters) below sea level to 40,000 feet (12,000 meters) above sea level
Shock	40 G, 3.75 ms up to 65 G, 3.75 ms triangular 20 G, 8 ms square or trapezoidal
Shock
Vibration	5 G, 5 to 150 Hz sinusoidal

Electrical Requirements

This section provides information regarding site power and wiring, module AC power requirements, and power cord routing instructions.

Site Wiring and Power

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.

Power Input

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.

TABLE 3-4 Tray AC Power Requirements
Condition	Specification
AC power (Controller tray)	2.65A maximum operating @ 240 VAC (180 to 264 VAC, 50/60Hz) 5.53A maximum operating @ 115VAC (90 to 136 VAC 50/60HZ)
AC power (Expansion tray)	1.97A maximum operating @ 240VAC (180 to 264 VAC, 50/60Hz) 4.11A maximum operating @ 115VAC (90 to 136 VAC 50/60HZ)

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).
