Power Specification for RP 5470.

The Power Specification for RP 5470 mentions power consumption as 1283 Watts.

Now there are three Power Supplies in the server. Are they for redundancy or load sharing ? My current understanding is that you need atleast 2 power supplies working to run the server.

The information is required from standpoint of distributing the Power cable to PDU in the rack as well.

Re: Power Specification for RP 5470.

Take a look at this...

http://docs.hp.com/hpux/onlinedocs/A5191-96018/A5191-96018.html

Go to "System Specifications - Electrical" section.

"At the server level, enhanced power availability is achieved through the n+1 hot-swappable power supplies.

One power supply is required for a minimally configured rp54xx system operation and in order to allow the system to boot. If a second power supply is present, one of the two power supplies can fail without the system shutting down. Similarly, two power supplies are required for a more heavily-configured rp54xx server. If a third power supply is present, one of the two power supplies can fail without the system shutting down.

If a third (redundant) power supply is present, all three power supplies become hot-swappable. Any one of the power supplies can fail without affecting system performance, and can be replaced while the system is on-line. Single point of failure is reduced to the local wall circuit or PowerTrust UPS to which the power supply power cords are connected. "

Re: Power Specification for RP 5470.

Please note that there are 2 required for the rp5470 and rp5450. the third is for redundancy.

On the rp5400 and rp5430 only 1 power supply id typically required.

each power supply supplies up to 930W

maximum power dissipations:
rp5470/rp5450/L3000/L2000: 1360W
rp5430/rp5400/L1500/L1000: 936W

So 3 power supplies would be required for redundancy.
