6.1 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 VAC to 240 VAC. 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).
