6.2 Basic information
AC PSU
The server can be equipped with up to two AC PSUs.
In its basic configuration, the server has one PSU that adjusts automatically to
any mains voltage in the range of 100 V - 240 V (AC PSU Platinum) or 200 V -
240 V (AC PSU Titanium). 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 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 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.
