Install Sun Storage 2500-M2 Arrays in accordance with the local safety codes and regulations at the facility site. Make sure that you read the safety precautions in the

Sun Storage 2500-M2 Arrays Regulatory and Safety Compliance Manual.

The following sections contain additional safety information for the local facility:

(8)

■ “Secure Installation Requirements” on page 2

■ “Placement of a Product” on page 2

Note –Do not make mechanical or electrical modifications to the equipment. Oracle Corp. is not responsible for regulatory compliance of a modified product.

Handling Precautions

Caution – A fully populated cabinet can weigh in excess of 1500 pounds (682 kg). Ensure that all surfaces this system will move over can withstand this load.

The cabinet is equipped with wheels so you can move it. Use enough personnel when moving the cabinet, especially on sloped loading docks and ramps, to gain access to a raised computer room floor. Move the cabinet slowly and deliberately, and make sure that the floor is free from foreign objects and cables that the cabinet could roll over.

Caution – To avoid injury, wear protective footwear when moving a system.

Secure Installation Requirements

To minimize personnel injury in the event of a seismic occurrence, you must securely fasten the cabinet to a rigid structure extending from the floor to the ceiling, or from the walls, of the room in which the cabinet is located.

Install the cabinet on a level surface. At each corner, on the base of the cabinet, are adjustable nonskid pads. Extend these pads when the cabinet is installed to prevent the cabinet from rolling. Do not use these pads to level the cabinet.

Placement of a Product

Allow enough room surrounding the cabinet for access to the cabinet and arrays for maintenance.

(9)

Chapter 1 Planning for the Installation 3 Caution – Do not block or cover the openings of your product. Never place a product near a radiator or heat register. Failure to follow these guidelines can cause overheating and affect the reliability of your product.

Air cools the system cabinets from front to back. Air enters at the front, circulates, and is expelled at the back of the cabinet. The front and back door clearances provide sufficient space for cooling. SeeChapter 2for specific clearance specifications.

Acoustic Noise

Shock and Vibration

TABLE 2-10lists the shock and vibration specifications for the controller tray.

Electrical Requirements

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

Site Wiring and Power

The controller tray uses wide-ranging redundant power supplies that automatically accommodate voltages to the AC power source or the optional –48-VDC power source. The power supplies meet standard voltage requirements for both North American (USA and Canada) operation and worldwide (except USA and Canada) operation. They use standard industrial wiring with line-to-neutral or line-to-line power connections.

Nonoperating (unpacked) 5-500-5 Hz, sinusoidal, 1 octave per minute, flat profile .50 G Shock Operating (no damage) 10-g peak acceleration, 5 ms duration, 1/2 sine pulse

(16)

Note – Power for the optional –48-VDC power configuration is supplied by a centralized DC power plant instead of the AC power source in the cabinet. Refer to the associated manufacturer’s documentation for specific DC power source

requirements.

Consider the following information when preparing the array’s installation site:

■ Protective ground—Site wiring must include a protective ground connection to the AC power source or the optional –48-VDC power source.

Note – Protective ground is also known as safety ground or chassis ground.

■ Circuit overloading—Power circuits and associated circuit breakers must provide sufficient power and overload protection. To prevent possible damage to the array, isolate its power source from large switching loads (such as air-conditioning motors, elevator motors, and factory loads).

■ Power interruptions—The controller tray can withstand the following applied voltage interruptions (with or without an integrated uninterruptible power supply [UPS]):

■ Input transient—50 percent of the nominal voltage ■ Duration—One-half cycle

■ Frequency—Once every 10 seconds

■ Power failures—If a total power failure occurs, the controller tray automatically performs a power-on recovery sequence without operator intervention after power is restored.

Note – When a power failure occurs, the controller tray uses battery power to back up the data that is in cache.

(17)

AC 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 inTABLE 2-11.

DC Power Input

The DC power source must provide the correct voltage, current, and frequency specified on the array nameplate label and the serial number label.

Nominal input voltages for the DC power source are as follows:

■ Input voltage: –42 to -60VDC

■ Operating current: 21.7 to 15.3A

Controller Tray Power Factor Correction

Power factor correction is applied within the power supply, which maintains the power factor of the controller tray at greater than 0.95 with nominal input voltage.

Power Cords and Receptacles

Sun Storage 2500-M2 Arrays are shipped with either two AC power cords or two DC power cords per tray, depending on the configuration ordered.

AC Power Cords

Each AC power cord connects one of the power supplies in a tray to an independent, external AC power source, such as a wall receptacle or a UPS.

If you have a cabinet with internal power cabling, such as a ladder cord, you do not need the AC power cords that are shipped with the controller-drive tray.

TABLE 2-11 Tray AC Power Requirements

Condition Specification

Input voltage 100 - 240V

Input frequency 50 or 60Hz

(18)

DC Power Connector Cables

Each –48-VDC power connector cable plugs into the DC power connector on the back of the controller tray. The three source wires on the other end of the power connector cable connect the tray to centralized DC power plant equipment, typically through a bus bar above the cabinet.

Caution –A qualified service person is required to make this DC power connection according to NEC and CEC guidelines.

Caution – Risk of electrical shock—This unit has more than one power source. To remove all power from the unit, all DC MAINS must be disconnected by removing all power connectors from the power supplies.

Two (optionally four) DC power connector cables are provided with each controller or expansion tray. Two DC power connectors are on the back of each tray’s DC power supply if additional redundancy is required.

Note –It is not mandatory that the second DC power connection on the array’s DC power supplies be connected. The second DC power connection is provided for additional redundancy only and may be connected to a second DC power bus.

Battery Life

For a fully rated battery backup unit (BBU) battery life, cell limitations are listed in
