Basic information

The server can be equipped with up to two hot-plug AC PSUs or DC PSUs.
The connectors for the PSUs are integrated on the system board,
therefore, the PSUs are connected directly to the system board.
Server equipped with up to two hot-plug 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 that operation can continue
uninterrupted and the defective PSU can be replaced during operation (hot-
plug). The second PSU can be installed during operation.
