Alternatively the hardware safety interlock is not satisfied.

SGI 500-750XTM IOM DOCR-070506-D tbl=31.r13 h=1ec1f6ad7fc8

review note: support check: partial - Description says interlock not satisfied or DC voltage too low to connect; DC undervoltage is one alternative only.

c4 drafted · lead DC voltage measurement

SGI 500-750XTM IOM DOCR-070506-D tbl=31.r13 h=1ec1f6ad7fc8

review note: support check: partial - Corrective action says verify DC voltage, but the passage doesn't say the fault is detected by DC voltage measurement.
