The server supports a mains voltage in the range of 200 - 240 V. You may 
only operate the server if its rated voltage range corresponds to the local 
mains voltage.

I

Phase redundancy is possible in regions, where a single phase provides 
200 - 240V; in other regions with lower single phase voltage, two phases 
must be coupled and complete phase redundancy thus is not possible.

In the basic configuration, the server is configured with three hot-plug power 
supply units. This ensures 2 + 1 power supply redundancy. One additional hot-
plug power supply unit can be installed to achieve AC redundancy in a 2+2 
configuration. For more information on the redundancy concept see 
"PRIMERGY RX900 S1 Server Operating Manual".

●

Areas around the power supply unit may remain extremely hot after 
shutdown. Wait for a while after shutdown before removing the power 
supply unit.

●

When installing the power supply unit, be sure to confirm that the 
connector of the PSU is not damaged or bent.

●

Do not insert your hands in the power supply unit slot when removing 
the power supply unit. Doing so may cause electric shock.

●

If the power supply unit is hard to remove, do not pull out it by force.

●

The power supply unit is heavy, so handle it carefully. If you drop it by 
mistake, injuries may result.
