Connecting The Server Enclosure To The Mains - Fujitsu Primergy CX400 S2 Operating Manual

5.4 Connecting the server enclosure to the
mains
The system has two bays for hot-swap power supply units. If one power supply
unit is defective a warning is generated and all CPUs will be forced to work with
the lowest frequency. Each hot-plug power supply unit can be replaced during
operation (see the "PRIMERGY CX400 S2 Upgrade and Maintenance
Manual").
V
CAUTION!
The server enclosure is automatically set to a mains voltage in the range
100 - 240 V. You may only operate the server enclosure if its rated
voltage range corresponds to the local mains voltage.
Ê Connect the power cord to the server enclosure PSU.
Ê Connect the mains connector to an outlet on the rack's socket strip (see also
Technical Manual for the rack).
I
A phase redundancy in the power supply of the server enclosure can be
set up if two hot-plug PSUs are installed.
In this case, each of the PSUs is either connected to two different phases
or to two separate circuits of the internal power supply network.
