104 Upgrade and Maintenance Manual RX1330 M3
Power supply unit (PSU)
6.1 Basic information
The server can be equipped:
– with a standard PSU (permanently built-in)
The PSU adjusts automatically to any mains voltage in the range of 100 V -
240 V.
– or up to two hot-plug PSUs (slide-in units)
In its basic configuration, the server has one PSU that adjusts automatically
to any mains voltage in the range of 100 V - 240 V. Besides the PSU, a
second PSU can be installed optionally to serve as a redundant PSU. 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).
– or one hot-plug PSU and a Fujitsu battery unit (FJBU)
Besides the PSU, an FJBU can be installed optionally as a modular UPS.
When power fail happened, the server can operate via FJBU for a while. The
FJBU can be replaced during operation (hot-plug).
V CAUTION!
The server supports a mains voltage in the range of 100 V - 240 V. You
may only operate the server if its rated voltage range corresponds to the
local mains voltage.
