I'd be interested as well, for two reasons. 1) I think the requirement
is a bit out of date, and really only discusses bringing in two DC power feeds,
A and B. That however seems more adapted to the days of simpler systems that
would take the power through some steering diodes and take it straight to a
back plane and power all of the cards in the box. As things have become more
complex systems inject system power supplies (DC-DC for example) into the
network but the standards don't seem to address the need for redundancy at this
point. Unfortunately, I don't have the document in my hands, it was a question
that came up during some recent testing.
2) Isn't L-10 a fan type of specification. The point at which 10% of
the fans fail. I have been chasing this question on and off for awhile.
Thanks
Gary

Subject: Bellcore Redundancy Requirements?
Does anyone in the collective know about _where_ Bellcore spells out any
sort of redundancy requirements.
There is a buzz about "L-10" requirements and I'm not sure where this comes
from.
TIA.
Regards,
John Kretsch
