Enough power in cabinet to support Netra 240s

I want to mount (14) Netra 240's in a single cabinet if possible. I need redundant power.

Looking at the power specs for the 240's, it appear they have a max draw of about <a href="mailto:3A&#64;220V." target="_blank">3A@220V.</a>

The 900 & 1000 Series cabinets look like they can be ordered W/PDS which would require (4) <a href="mailto:16A&#64;220v" target="_blank">16A@220v</a> AC ckts. So that would give me 32A redundant power.

If my math is correct, the max draw for each 240 is 3A. So 14x3= 42A total amps.

So if I'm reading this correctly, the 900 or 1000 series cabinets will not give me enough power to support (14) Netra 240s. Is that correct?

If so, what are my options other then splitting them up in two cabinets?

Any help would be greatly appreciated!!!

Thanks,

JB

Buy the rack without the PDM and power the servers from a distribution panel from the main grid. This will give more scalable power distribution for the NEBS environment ( I assume that is why you are using Netra systems ) if the PDM has a limit. I'll look into this a bit more tomorrow, perhaps Bill will have some input on this as well.

Sorry, but my experience with racks and their power components has been limited to... "It's broken?You have a service contract?Let me send you a new component." I've never been involved with configuring them.

Sorry Bill, but you are very knowledgeable on these topics most of the time! Faced with a scenario like this I would go for the empty rack and employ the services of an experienced electrical engineer. I have seen some very creative custom solutions put together by sparks to resolve issues like this.
