Power supply unit (PSU)
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.
Server equipped with up to two hot-plug DC PSUs
In its basic configuration the server has one PSU that adjusts automatically to
any mains voltage in the range of -48.0 V - -57 V (DC PSU -48 V) or 200 V -
380 V (HVDC PSU 380 V). Besides the PSU, a second PSU can be installed
optionally to serve as a redundant power supply. If one PSU fails, the second
PSU in the redundant configuration ensures that operation can continue
uninterrupted and the defective PSU can be replaced during operation (hot-
plug). The second PSU can be installed during operation.
CAUTION
The DC PSU adjusts automatically to any mains voltage in the range
from -40.5 V - -57 V.

You may only operate the server if its rated voltage range
corresponds to the local mains voltage.
CAUTION
The HVDC PSU adjusts automatically to any mains voltage in the range
from 200 V – 380 V.
