Quick question - 5108 chassis max power

Hey guys, hopefully this is an easy one. What is the maximum power draw that a 5108 chassis can handle? In other words, how many amps can the chassis actually take? I thought I heard 32A at some point, but I can't find it in any documentation.

Thanks

John ,

The Cisco UCS 5108 Blade Server Chassis is powered by 208 V (220 V outside the US) 50-60 Hz AC. Up to four power supply units (PSUs) may be installed, each with a single C20 connector for input power connection to the UCS 5108 power supply.

Check the following document:

Hope this helps!

That's not what I was asking. This isn't in any of the cisco documentation I've seen. It's an oddball question, so don't worry about it.

Max power is 7500 watts assuming you are running four power supplies in N + 1 mode.
