IMPORTANT:
Do not unmount the power supply unit that is operating properly.
NOTE:
When the server is running under the power redundant configuration
and the minimum number of servers are running properly (Status LED of
the power supply unit is lighting), the power supply unit can be replaced
even when the system is operating (power-on status).
IMPORTANT:
Pull out the power supply unit horizontally. The power supply unit or
internal connector may be damaged if it is inclined or pressure is added
from side to side and up and down while pulling out.
