For full redundancy 6 Power Supply Option Kits are required.<BR /><BR />i want any one explain this i don't under stand what is the minimum no of power supply that i need to install when using three phase and tell me if i want use it in N+1 mode and N+N mode Wed, 15 Dec 2010 09:04:50 GMT maximodb 2010-12-15T09:04:50Z https://community.hpe.com/t5/bladesystem-general/power-supply-explain/m-p/4726725#M12259 hello all ,<BR />i get this quote from hp manual guide <BR /><BR />NOTE: If Three Phase Power Module selected, a minimum of 3 Power Supply Option<BR />Kits are needed.

For 1-phase the minimum number of PS is 2.<BR /><BR />If you have already 3-phase electrical infrastructure you can use 3-phase PDU (one 3-phase input, 6 1-phase output for connection to 1-phase PS). The recommended solutions are:<BR /><BR /><BR />HP Modular Power Distribution Units (AF513A or AF518A) and HP 2400W High Efficiency Power Supplies (499243-B21 or 517521-B21)<BR /><BR />or<BR /><BR />HP Intelligent Power Distribution Units (iPDU) (AF526A or AF527A) and HP 2400W Platinum Efficiency Power Supplies (588603-B21 or 517521-B22)<BR /><BR />Read the doc:<BR />Technologies in the HP BladeSystem c7000 Enclosure<BR /><A href="http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00816246/c00816246.pdf" target="_blank">http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00816246/c00816246.pdf</A> Wed, 15 Dec 2010 10:00:26 GMT https://community.hpe.com/t5/bladesystem-general/power-supply-explain/m-p/4726726#M12260 Zygmunt Krawczyk 2010-12-15T10:00:26Z
