Hardware Installation
Restarting the PC
Normally, you can power-off the PC by:
1. Pressing the power button at the front panel of the chassis.
or
2. Pressing the power switch that is on the system board (note: not all system
boards come with this switch).
If for some reasons you need to totally cut off the power supplied to the PC,
switch off the power supply or unplug the power cord. Take note though that if
you intend to restart it at once, please strictly follow the steps below.
1. The time where power is totally discharged varies among power supplies. It’s
discharge time is highly dependent on the system’s configuration such as the
wattage of the power supply, the sequence of the supplied power as well as
the number of peripheral devices connected to the system. Due to this rea-
son, we strongly recommend that you wait for the Standby Power LED (refer
to the “LEDs” section in this chapter for the location of the Standby Power
LED) to lit off.
2. After the Standby Power LED has lit off, wait for 6 seconds before powering
on the PC.
If the system board is already enclosed in a chassis which apparently will not
make the Standby Power LED visible, wait for 15 seconds before you restore
power connections. 15 seconds is approximately the time that will take the
LED to lit off and the time needed before restoring power.
The above will ensure protection and prevent damage to the motherboard and
components.
