4.6 Connecting the power cord (AC PSU)
CAUTION
The server automatically adjusts to a mains voltage in the range from
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 to the PSU.
▶
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
429.
It will take about 60 seconds until the server can be powered on.
Using the hook-and-loop-tape
Y
ou can secure the power cord with a hook-and-loop-tape to ensure that the
power cord cannot be disconnected from the server by mistake. The hook-and-
loop-tape is included in the accessories pack that is delivered together with the
server.
