LOTO Service Documentation is Accessible via the Service Methods Website by
clicking on "Safety" and then the correct procedure name under "Lock Out Tag
Out". Note that for SV, all LOTO procedures involving LOTO of the SYSTEMS
CABINET require shut down of the Simple OC first. This is because powering
down the Simple OC ensures correct soft power down of the Image Compute
Node. The ICN MUST be shut down via a soft power down in order to avoid
operating system corruption!
