3.1 Server
3.1.3 Connecting the servers to the mains
The ETERNUS CS800 servers are equipped with two hot-plug power supply units. If one
power supply unit is defective, then the other guarantees unimpaired operation. Each hot-plug
power supply unit can be replaced during operation.
CAUTION!
The server is automatically set to a mains voltage in the range 100 V - 240 V. You
may only operate the server if its rated voltage range corresponds to the local
mains voltage.
Connect the power cord with the insulated connector to the power supply unit of the
server, and plug the power plug into a grounded outlet on the mains socket strip on the
rack (see Technical Manual of the rack).
A phase redundancy in the power supply of the server can be set up if each of the
power supply units is either connected to two different phases or to two separate
circuits of the internal power supply network.
Using the cable clamp
You can secure the power cords in a cable clamp to ensure that the insulated connectors
cannot be disconnected from the server accidentally.
