requires considering the following factors: • Voltage level provided by the facility • Type of power connectors to be used • Estimated power consumption • Power redundancy • System expansion • Serviceability Failure to account for these factors can result in unscheduled downtime from equipment - HP ProLiant DL160se | Critical factors in intra-rack power distribution planning - Page 3
serviceability and enable sequential startup • Achieve balanced loading between dual power buses • Support redundant operation of equipment with redundant power supplies range, depending on which level is supplied to the rack. Most HP server equipment features auto-sensing input circuitry that - HP ProLiant DL160se | Critical factors in intra-rack power distribution planning - Page 4
more common in other regions. For more information on AC power connector types refer to the HP technology brief "Selecting power cords and jumper cables for use with HP ProLiant servers" at the following URL: http://h18004.www1.hp.com/products/servers/technology/whitepapers/datacenter.html 4 - HP ProLiant DL160se | Critical factors in intra-rack power distribution planning - Page 5
into the calculator. With accurate estimates of power requirements for individual server chassis, infrastructure designers can easily calculate power consumption for a fully-configured rack. A catalog of HP Power Calculators is available for downloading at the following URL: http://h71028.www7 - HP ProLiant DL160se | Critical factors in intra-rack power distribution planning - Page 6
leave little room for power components or cables. These systems may require a rack extension kit (Figure 4) to accommodate cables and PDUs and to allow access to field-serviceable components. Two optional rack extensions kits, a 42U kit and a 36U kit, are available for the HP 10000 series equipment - HP ProLiant DL160se | Critical factors in intra-rack power distribution planning - Page 7
PDUs that individually support multiple load segments (Figure 5B). In either case, a circuit breaker is associated with each load segment (LS). Figure 5. Segmented power distribution A.

Redundant power distribution Redundant power systems require two power distribution circuits, one for each power bus. Redundant operation requires configuring servers with redundant power supplies, each capable of supporting the full load of a server, if necessary. For redundant operation, the PDU - HP ProLiant DL160se | Critical factors in intra-rack power distribution planning - Page 9
Module can also be integrated with SNMP management software such as HP Systems Insight Manger (SIM) that can receive and log SNMP traps (alerts) to manage alarm conditions. Other considerations An effective power distribution solution for a high-density rack involves much more than meeting - HP ProLiant DL160se | Critical factors in intra-rack power distribution planning - Page 10
Enclosure uses auto-ranging power supplies and supports redundant power supply configurations. Up to four BladeSystem c7000 enclosures can be installed in a standard 42U rack. Figure 7.

Table 2. Power distribution configurations for using one to four HP BladeSystem c7000 enclosures in a standard rack No. of c7000 provided in the "For more information" section. [2] Configuration requires optional 600mm rack extension kit (P/N AF058A).

to HP ProLiant DL servers This section describes power distribution configurations for a high-density server system based on HP ProLiant DL 360 G5 servers. The ProLiant DL 360 G5 is a 1U server that uses an auto-ranging power supply and supports power redundancy when used in the 1 + 1 power supply - HP ProLiant DL160se | Critical factors in intra-rack power distribution planning - Page 13
to ensure that safety, availability, and manageability are not compromised. The variety of power distribution products available from HP allows an almost unlimited number of power distribution configurations to satisfy those goals. NOTE: Products and part numbers discussed in this document are
