A minimum configuration consists of one DKC and one DKU.
Data Comm Requirements Route data communications cables away from areas of high static electric fields created by power transformers and heavy foot traffic. Use shielded data comm cables that meet approved industrial standards to reduce the effects of external fields. Phone Home With Continuous Track The HP SureStore E Disk Array XP512 Phone Home capabilities detect and report problems even before they are noticed by operators and users.
Local Area Network (LAN) Two software products are especially useful in managing your disk array: • HP SureStore E Remote Control XP • HP SureStore E Command View XP Remote Control XP and Your Private LAN HP SureStore E Remote Control XP is a software application that permits you to connect to, monitor, and manage up to 8 disk arrays. It communicates directly with the DKC of each attached disk array. The software runs on a PC called a remote console.
HP SureStore E Command View XP and Your Public Intranet HP SureStore E Command View XP is a web-based software application that permits you to connect to, monitor, and manage disk arrays. You can remotely manage your HP SureStore E Disk Array XP512 from any location, enabling a remote expert to participate in problem management. To connect to your Intranet (public LAN), your CE will directly connect your HP SureStore E Disk Array XP512 to an available Ethernet port on your public LAN.
Electrical Requirements Power requirements are one of the most important considerations prior to installing your disk array. Each disk array has two separate connections to AC power, so the rated AC current should be doubled. In case one input fails, the second input MUST BE CAPABLE OF SUPPORTING THE ENTIRE CURRENT DEMAND FOR BOTH SETS OF POWER SUPPLIES. Line Voltage The line voltage (AC) at the wall power outlet is a function of the local power utility and your building power distribution network.
Frequency AC line frequency is normally determined by your local power providers. In some cases, electrical power is supplied by motor-generators. Shifts in AC line frequency can cause system errors. Your HP CE can monitor the frequency of the input AC line power and make recommendations, if necessary.

Receptacles When receptacles are used to connect your disk array components to AC power, they must include a dedicated ground connection that is insulated from the receptacle. It is important that the receptacle box be grounded with an additional ground connection that is nondedicated. The additional ground can be hard conduit. Each disk array has two separate connections to AC power, and the second input must be capable of supporting the entire current demand for both sets of power supplies.
If necessary, your HP CE can measure your power line noise level and make appropriate recommendations concerning the use of line treatment devices. Maximum Peak Inrush and Crest Factor The inrush current for the HP SureStore E Disk Array XP512 is: 3-Phase 60 amps for the first DKU 25 amps for 2nd DKU Single-Phase 50 amps for the first DKU 40 amps for DKC Crest Factor The crest-factor for the HP SureStore E Disk Array XP512 is 1.68.
Sources of Electrical Interference Ensure that the disk array is protected from sources of electrical interference: wall outlets Convenience power outlets for building maintenance equipment (vacuum cleaners, floor buffers, etc.) must be wired from circuit breakers on a power panel separate from the computer system panel. The ground wires from these outlets must be connected to the normal building distribution panel and not to the system ground.
many of the most common causes of electromagnetic interference. metal If metal is used in the construction of the raised floor, ensure that there is a common ground connection between the raised floor and main floor to avoid possible build up of different voltage potentials. Failure to comply can result in serious injury to personnel and damage to equipment. flammable materials Fundamental safeguards for disk arrays should include a site well away from any sources of potential damage.
3-Phase AC Cabling for USA Connecting the External Power Supply Cord The DKU has two power supply cords. If one power source malfunctions, the other power source will assume the total load, causing no data loss. It is also good practice to put each power cord on a different electrical circuit, in case of a circuit failure. Each power supply cord is supplied with an attachment plug type R&S FS 3760.
The protective device on building installation shall comply with national standards of the country where the units shall be installed, and if a protective device interrupts a conductor, it shall also interrupt all other supply conductors This protection is not required for the neutral line of this unit.
3-Phase AC Cabling for Europe Caution The DKC and the basic DKU commonly have two main disconnect devices (two main breakers for dual power lines) so that AC Power of the unit can be supplied from the separate power distribution board with two power supply cords. Similarly, each of the 2nd DKU, the 3rd DKU, the 4th DKU, the 5th DKU, and the 6th DKU also has two main disconnect devices.
