6.2 Basic information
The server can be equipped with up to two hot-plug PSUs that automatically
adjust to any mains voltage in the range of 100 V - 240 V (AC PSU Platinum)
or 200 V - 240 V (AC PSU Titanium).
To serve as a redundant power supply support: If one PSU fails, the second
PSU in the redundant configuration ensures operation can continue
uninterrupted and the defective PSU can be replaced during operation (hot-
plug).
To serve as non-redundant power supply support: If one PSU fails, the system
may run with CPUs power capping (performance limited) condition to operate
or may shutdown triggered by PSU that depends on actual power loading.
CAUTION
The AC PSU adjusts automatically to any mains voltage in the range
from 100 V - 240 V (AC PSU Platinum) or 200 V - 240 V (AC PSU
Titanium).
▶
You may only operate the server if its rated voltage range
corresponds to the local mains voltage.
