Mini Tower Computer
This latch allows you to open the computer cover.
Insert a padlock to lock the computer cover.
Your computer is 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 "Back-Panel
Connectors" on page 25.
Access connectors for any installed PCI and PCI Express cards.
