Power Specification for RP 5470.

[Nirav Dalal]

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.

Take a look at this...

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. "

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.
