CAUTION To avoid damage to your server, be sure to set the input voltage selector switch to a
setting within the voltage range of the power source you intend to use. Always
check the switch setting before connecting the power cord.
1. If your input voltage is in the range of 100 V to 127 V, set the voltage selector to
the 115 setting.
2. If your input voltage is in the range of 200 V to 240 V, set the voltage selector to
the 230 setting.
NOTE System models Dx70, Dx80, and D390 have a power supply that automatically
switches to match the input voltage level. There is no voltage selector switch on
these models.
