TX1320 M4
Power supply unit (PSU)
6.1 Basic information
The server can be equipped:
– with a standard PSU
The PSU adjusts automatically to any mains voltage in the range of 100 V -
240 V.
– with up to two hot-plug 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. 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.
– with 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.
Assembly rules
– Always install a dummy cover into an unused PSU bay to comply with
applicable EMC regulations and satisfy cooling requirements.
– For a redundant power supply configuration you need always two PSUs with
the same power class.
