[. . . ] HP StorageWorks Modular Smart Array 50 Storage Enclosure User Guide May 2005 (Second Edition) Part Number 379396-002 © Copyright 2005 Hewlett-Packard Development Company, L. P. The only warranties for HP products and services are set forth in the express warranty statements accompanying such products and services. Nothing herein should be construed as constituting an additional warranty. HP shall not be liable for technical or editorial errors or omissions contained herein. [. . . ] Observe the following guidelines: · · · · Balance the storage enclosure power load between available AC supply branch circuits. Do not allow the overall system AC current load to exceed 80 percent of the branch circuit AC current rating. Provide a separate electrical circuit for each power supply in the storage enclosure. Setup 19 Electrical grounding requirements The storage enclosure must be grounded properly for proper operation and safety. In the United States, you must install the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250, as well as any local and regional building codes. In Canada, you must install the equipment in accordance with Canadian Standards Association, CSA C22. 1, Canadian Electrical Code. In all other countries, you must install the equipment in accordance with any regional or national electrical wiring codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you must be sure that all power distribution devices used in the installation, such as branch wiring and receptacles, are listed or certified grounding-type devices. Because of the high ground-leakage currents associated with multiple storage enclosure connected to the same power source, HP recommends the use of a power distribution unit (PDU) that is either permanently wired to the building's branch circuit or includes a nondetachable cord that is wired to an industrial-style plug. NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for this purpose. Using common power outlet strips for the storage enclosure is not recommended. Rack warnings WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that: · · · · · The leveling jacks are extended to the floor. The stabilizing feet are attached to the rack if it is a single-rack installation. A rack may become unstable if more than one component is extended for any reason. WARNING: To reduce the risk of personal injury or equipment damage when unloading a rack: 20 HP StorageWorks Modular Smart Array 50 Storage Enclosure User Guide · At least two people are needed to safely unload the rack from the pallet. An empty 42U rack can weigh as much as 115 kg (253 lb), can stand more than 2. 1 m (7 ft) tall, and may become unstable when being moved on its casters. Never stand in front of the rack when it is rolling down the ramp from the pallet.
