Setting Up Your Fiber-Optic MXI-Express for PXI Express
Powering Down the Fiber-Optic MXI-Express x4 System
Because operating systems and drivers commonly make the assumption
that PCI devices will be present in the system from power-up to
power-down, it is important not to power off the expansion chassis until
after the host PC is powered off. Powering off the expansion chassis while
the host is still on can cause crashes or hangs.
After the host computer has powered down, the order in which expansion
chassis are powered off relative to each other is not important. However, to
power down a chassis that still has its upstream link active, the power
button must be pressed for at least 4 seconds.
