[rescue] Sun Netra 240 w/ 48V Power Supplies- How much current do I need to run it?

FWIW, back when these were still in production, or, at least still supported, I was working for a large retailer, and we had ~50 of
them on the 'web tier', in support of the online catalog, web sales, etc.

Apparently, many of the 240's were put out during a transitional time, and I can't count the number of times that Sun went back for
the right part, when they were out for repair.  Specifically, some boxes were ROHS compliant (that we owned), and others weren't.

For the purpose of this discussion, I do NOT believe that power supplies ever played into that, but, it seems that every time I pick
up a new SPARC system, its always my plan to max out memory, CPU, etc.  Assuming that others do the same.   Food for thought.

Just a quick thing to check the main fans which were a hot item requested for
spares. They used to be expensive items.

I picked up a Sun Netra 240 at U of M surplus for a whopping 5 dollars.

However to run it,  I need to supply it with 48v power.   It came out
of a telco central office.   Any idea how big of PSU i need to run it?
