[mod.computers.vax] maximum current draws

SYSRUTH@UTORPHYS.BITNET (01/05/87)

Does anybody have any experience running a uVAX-II BA23 box with slightly
more than the maximum current recommendation being drawn at +5V (we would
have less than 10% of +12V maximum and be 40W shy of max.power in the
proposed configuration)? Can the DEC specifications be taken with a grain
of salt, say to 10 or 20%?

Incidentally, does anybody but DEC specify AC/DC bus loads for their boards?
And does anybody but DEC know what they mean by "I/O inserts"? I'd be
interested to know these things.

If we put into our BA23 all the things we would like to, we would be drawing
about 38.5A at +5V. The maximum DEC specifies is 36.0A.

Thanks in advance for info. on this.

P.S. Thanks to Marty Sasaki for a prompt answer on my expansion BA23 query
(independent of this one - not the same machine).
