Quick Reference Guide
Your computer may be equipped with a manual voltage-
selection switch.
To help avoid damaging a computer with a manual voltage
selection switch, set the switch for the voltage that most
closely matches the AC power available in your location.
NOTICE:
In Japan, the voltage selection switch must be
set to the 115-V position even though the AC power
available in Japan is 100 V.
Also, ensure that your monitor and attached devices are
electrically rated to operate with the AC power available in
your location.
Insert the power cable.
Plug serial, USB, and other devices into the appropriate
connectors. See "Mini Tower Computer — Back-Panel
Connectors" on page 19.
Access connectors for any installed PCI and PCI Express
cards.
