Common Power Source
We strongly recommend that all chassis power supplies have the same power
source as the input and output devices. This helps reduce the chance of
electrical interference due to multiple sources and grounds, as well as maintain
system integrity if power is interrupted.
If you do not use a common power source, you need to apply power to the
expansion chassis before you apply power to the chassis containing the adapter to
avoid an unwanted fault. That is, if the adapter detects the absence of power to any
chassis in the system, the STAT LED turns on and all adapter outputs are
de-energized.
