Basic hardware procedures
4.6 Connecting the power cord
4.6.1 Connecting the power cord (AC PSU)
V CAUTION!
The AC PSU adjusts automatically to any power voltage in the range
from 100 V - 240 V (AC PSU Platinum) or 200 V - 240 V (AC PSU
Titanium). You may only operate the server if its rated voltage range
corresponds to the local mains voltage.
Ê Connect the power cords to the PSUs.
Ê If applicable, connect the mains plugs to power outlets of the rack socket
strip.
I To provide true phase redundancy, the second PSU should be
connected to a different AC power source from the other PSU. If one
AC power source should fail, the server will still continue to run.
Ê Ensure that the status indicator on the PSU is lit green (see section
"Indicator on hot-plug PSU" on page 566).
