4.6 Connecting the server to the mains
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.
Ê If applicable, connect the mains plugs to power outlets of the rack socket
strip.
I To provide true phase redundancy, the second power supply unit
should be connected to a different AC power source from the other
power supply unit. If one AC power source should fail, the server will
still continue to run.
Ê Connect the power cords to the power supply units.
Ê Ensure that the status indicator on the power supply unit is lit green (see
section "Indicators on power supply units (slide-in units)" on page 364).
