G
Reconfiguring the computer to operate from 115 or 230 Vac line volt-
age must be done only by qualified personnel. Before changing
from 115 Vac to 230 Vac configuration, or vice versa, set the power
switch on the front of the box to OFF, the Battery Enable switch to
DISABLE, and disconnect the power cord. Failure to observe this
precaution can result in serious injury or in damage to the power
supply.
The computer's ac line voltage configuration is determined by the position of the ac line
configuration/fan power connector (refer to P7 and P8 in Figure 2-2). Carry out the following
steps to change the position of the ac line configuration/fan power connector.

you are reconfiguring the power supply from 115 Vac to 230 Vac operation, apply the
230 Vac label to the back panel of the computer.
If you are reconfiguring the power supply from 230 Vac to 115 Vac operation, apply the
115 Vac label to the back panel of the computer.
2.
Remove the front panel of the computer and the fan panel, as described previously.
