4.7 Connecting the power cord
4.7.1
Connecting the power cord (AC PSU)
CAUTION
The AC PSU adjusts automatically to any mains 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.
▶
Connect the power cord to the PSU.
▶
If applicable, connect the main plug to an power outlet of the rack socket
strip.
To provide true phase redundancy, the second PSU should be
connected to a dif
ferent AC power source from the other PSU. If one
AC power source should fail, the server will still continue to run.
▶
Ensure that the status indicator on the PSU is lit green, see "Indicator on
hot-plug PSU" on page
553.
It will take about 60 seconds until the server can be powered on.
You can secure the power cord with a cable clamp or a hook-and-loop
tape to ensure that the power cord cannot be disconnected from the
server by mistake.
