To check the power cables, and connections:
•
Check the power outlet, the power cord, and any power switches
that may affect your POS Terminal. Check the wall outlet or
power strip with an item that you know is functioning properly (a
lamp or radio is a convenient item for checking the power). You
may also need to check the fuses and breakers in your electric box.
If the outlet is controlled by a wall switch, make sure that the
switch is on. If your POS Terminal is plugged into a power strip
with an on/off switch, make sure the switch is on.
•
With the POS Terminal’s power switched off, check all cable
connections. If the POS Terminal is connected to any peripheral
devices, look for loose or disconnected cables. If the POS
Terminal is too close to a wall, a cable connection may be loose
or the cables may be crimped.
Warning! Do not substitute cables for different devices (other than
the manufacturer recommended cables) even if they look
exactly alike. The wiring inside the cable may be different.
When you are certain that you have power available and all connections
are good, turn the POS Terminal on again. If the POS Terminal still does
not start, you may have a hardware problem.

The Power-On Self Test (POST) runs every time you turn on or reset the
POS Terminal. The POST checks memory, the mainboard, the display, the
keyboard, the disk drives, and other installed options.
A few seconds after you turn on your POS Terminal, a copyright message
appears on your display screen. A memory test message appears next; as
the test continues, memory size increases until all installed memory is
tested. Normally, the only test routine visible on the screen will be the
memory test.
