To avoid having to reboot system controllers and PCs, use the A to D power-on sequence
illustrated in Figure 4.
Figure 4.
Power Sequence for an Example PXImc System
1.
Power on all daisy-chained PXI or PXI-Express chassis that are not controlled by an
embedded controller, and do not have cable links with “mc” ports involved. The item that
follows power sequence A in Figure 4 meets these criteria.
2.
Power on any applicable PXI-Express chassis and/or PCs that contain ‘mc’ cable ports
(for example, the NI PXIe-8383mc) but are not cabled to other sub-systems that contain
“mc” port(s) and are still powered off. Allow time for the operating system to begin loading
before proceeding to the next step. The three items that follow power sequence B in
Figure 4 meet these criteria.
Caution
Do not power on any chassis or PCs if it they are cabled to “mc” port(s)
in other systems that are powered off. Doing so will prevent the PXImc Logic
Block(s) from recognizing the system that is cabled to it, and the system that contains
the PXImc Logic Block(s) will need to be rebooted to resolve this issue.
