keyword=Fastbus crate
The Fastbus crate was having some serious issues. Voltages were incorrect
and one of the 15V fuses kept tripping. We pulled the modules, no
improvement. We brought down the spare supply from Physics Storage. After
we swapped that one out the -5.2V supply would shutdown. We swapped the
-5.2V out. This refurbished one also kept shutting down. We changed +5
and -5.2 supplies around. The refurbished one shut down (it was then the
+5V supply). We swapped that one out. Voltages seemed to be stable.
