[BBLISA] PDU Power Ratings?

[Scott Danek]

Hi All,

Thanks for all the suggestions.  They've cleared up a lot of questions 
that we've had and have been extremely helpful.  It was my suspicion that 
using a 120V PDU on a 208V circuit probably wouldn't be the best idea.  We 
have some APC PDU's in mind and we'll probably start looking into going 
208V 20 amp in our colo.  Thanks all for your help!

-Scott

I won't add to the recommendations that avoid retasking a PDU
that isn't rated for how you're going to use it.  I agree that it's a
bad idea.

As for vendors, you might also want to check out servertech.com
in addition to APC. I've been quite happy with their product line.
