6.2 Basic information
The server is equipped with two hot-plug PSUs that automatically adjust to any
mains voltage in the range of 100
V - 240 V.
If one hot-plug PSU fails, the second hot-plug PSU in the redundant
configuration ensures that the operation can continue uninterrupted and the
defective PSU can be replaced during operation (hot-plug).
CAUTION
The server supports a mains voltage in the range of 100 V to 240 V
(1600 W PSUs).
â–¶
You may only operate the server if its rated voltage range
corresponds to the local mains voltage.
