Basic information

The server enclosure uses a hot-plug PSU, which automatically sets itself to a
mains voltage in the range of 200 - 240 V. (For the Japanese market there are
two PSUs available: PSU for 100V is set to a mains voltage in the range of 100V
- 240V). As an option, the power supply can be expanded with an extra PSU to
create a redundant power supply. If a PSU fails, the redundant configuration
assures continued operation. The defective PSU can be replaced during
operation.
Complete PSU redundancy will work only in one-node configuration.
In a multi-node configuration, full redundancy cannot be guaranteed. In case of
PSU failure a warning is generated and all CPUs will be forced to work with the
lowest frequency.
