Overview
The PSMs are hot swappable, which means they can be removed and replaced while the
FSP 3000 C system is powered on and running.
l Redundant power configuration — You can replace or upgrade a PSM while the
system is operating. Only one PSM can be replaced at a time. The second PSM must
remain connected to the AC or DC power source.
l Non-redundant power configuration — You will need to completely power off the
system when removing and replacing a PSM.
