Notes:
v For SRC 1xxx-8711, check that the bulk power regulator (BPR) is switched on before replacing any
parts.
v When DC converter assembly (DCA) cable SRCs of 1xxC- xx15, xx25, xx35, xx45, xx55, xx65, and
motor drive assembly (MDA) cable SRCs of 1xxC- xx75, xx85, xx95, xxA5 occur:
– Both the A-side and the B-side cables of the unit called out may be failing.
– Replace the cables for that unit until the error is corrected. That is, if the error is corrected after
replacing the first selected cable, then this ends the procedure. Otherwise, continue to the second
cable.
