Dear All,
The power supply (BCN 5/120) in the X32 rack of our ARX-300 keeps resetting itself with a -5V error LED. I replaced the corresponding module with the current Lambda equivalent, but the PS is refusing to stay powered up, despite all outputs from the other modules being correct with no significant AC ripple as measured with a Fluke multimeter. Removing the boards from the rack doesn't fix the problem.
I am suspecting module 5, the supervisor and +/-15 V source may be the culprit. If anybody out there happens to have a PS or module 5 they are willing to part with, let me know.
Also, if you have a decommissioned 300 MHz console (DPX onward) that you are willing to part with, I'm all ears.
Thanks in advance,
Ivan
