Thanks in advance, Darren Hi, I think you mind 19x174: 19 lists thestatus ofONE LED for not redundant systems. 119 lists the status of ALL LED for not redundant systems. 74 lists thestatus ofONE LED for redundant systems. 174 lists thestatus ofALL LED for redundantsystems.

I haven't tried to see what would be returned if one CPU was offline (i.e. no power).
