I have unit down with similar problem.:
Original condition: Power supply(P-16835)both led's ON; could not reset. SRB 'RST" ON, Could not reset. NO out put 's on.
Replaced Power supply board. Both RST led's (on pwr.sup. & SRB) flash on regular clock ; No output boards on. Voltage checks all appear correct.
My 'miprom' info is for '80's miproms. this system installed 1999. upper card rack is pwr, & inputs. Lower rack is outputs. Suspect a card rack but have no info on how to isolate failure to one.
Any Help ?
