Chapter 2: Basic installation
2.10 Replacing the power supply unit
Replace the power supply unit (PSU) after installing the system
components and reconnecting the cables.
To replace the PSU:
Make sure the PSU cables do not interfere with the CPU and/or chassis
fans.
Voltage selector
The PSU has a 115 V/230 V voltage selector
switch located beside the power connector. Use
this switch to select the appropriate system
input voltage according to the voltage supply in
your area.
If the voltage supply in your area is 100-127 V,
set the switch to 115 V.
If the voltage supply in your area is 200-240 V,
set the switch to 230 V.
Setting the switch to 115 V in a 230 V environment will seriously
damage the system!
