Chapter 2 Standard Hardware and Upgrades
Precautions
Before performing hardware changes, be sure to carefully read all of the applicable instructions, cautions,
and warnings in this guide.
WARNING! To reduce the risk of personal injury from electrical shock, hot surfaces, or fire:
Disconnect the power cord from the wall outlet and allow the internal system
components to cool before touching.
Do not plug telecommunications or telephone connectors into the network
interface controller receptacles.
Do not disable the power cord grounding plug. The grounding plug is an
important safety feature.
Plug the power cord in a grounded (earthed) outlet that is easily accessible at all
times.
CAUTION: Static electricity can damage the electrical components of the computer and/or
optional equipment. Before beginning these procedures, ensure that you are
discharged of static electricity by briefly touching a grounded metal object.
When the computer is plugged into an AC power source, voltage is always
applied to the main board. You must disconnect the power cord from the power
source before opening the unit to prevent damage to internal components.
Adjusting LCD Panel Height and Angle
The POS-420 Expander plus is equipped with dual hinges to provide flexible adjustment of the LCD display
and arm angle. The lower hinge is used for adjusting the arm angle, or the overall height of the POS
system, whereas the upper hinge is used for adjusting the display viewing angle.
For adjusting display viewing angle
For adjusting arm angle

10
Adjust View Angle
To adjust the display viewing angle firmly grip the display, preferably with one hand on top of the panel,
the other on the bottom, and rotate it on the hinge in the preferred direction.
Adjust Arm Angle
WARNING! Failure to completely release the lock may cause hinge damage when pressing
down on the arm.
1. Completely release the hinge lock. (Make at least 4 complete turns counter clockwise)
2. First adjust the arm to the preferred angle, then the height.
3. Relock the hinge. (Turn clockwise until completely engaged.)

11
Removing and Opening System Box
CAUTION: To prevent loss of work and damage to the system or drive:
If you are inserting or removing a drive, shut down the operating system
properly, turn off the system, and unplug the power cord. Do not remove a drive
while the system is on or in standby mode.
Before handling a drive, ensure that you are discharged of static electricity. While
handling a drive, avoid touching the connector.
1. Turn off the system power properly through the operating system, then turn off any external
devices.
2. Disconnect the power cord from the power outlet and disconnect any external devices.
3. Unlock the system box.
4. Firmly and slowly pull on the handle to remove the system box.
5. Remove the two screws indicated at the rear of the system box.

6. Slide the system box cover in the direction of the arrow, then lift off and set aside.
Clearing CMOS
The POS-420 Expander plus's configuration (CMOS) may occasionally be corrupted. If it is, it will be
necessary to clear the CMOS memory using jumper JP4. Please refer to Chapter 4 for the exact JP4 pin
positions.
1. Turn off the system power properly through the operating system, then turn off any external
devices.
2. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION: Regardless of the power-on state, voltage is always present on the main board as
long as the system is plugged into an active AC outlet. The power cord must be
disconnected from the power source before clearing the CMOS.
NOTE: All LEDs on the board should be OFF. Failure to ensure there is no power in the
system may damage the main board. You must disconnect the power cord to
avoid damage to the internal components of the system.
3. Remove the system box and box cover.
4. Locate the JP4 jumper box on the main board.
5. Remove the jumper shunt from pins 2-3 and place over pins 1-2.
6. Wait 60 seconds to allow the CMOS to clear, then remove the jumper shunt and place it back in its
original position over pins 2-3.
7. Replace the box cover and system box into the system.

13
Compact Flash Card Installation
1. Turn off the system power properly through the operating system, then turn off any external
devices.
2. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION: Regardless of the power-on state, voltage is always present on the main board as
long as the system is plugged into an active AC outlet. You must disconnect the
power cord to avoid damage to the internal components of the system.
3. Remove the system box and cover.
4. Locate the Compact Flash (CF) card socket in the side of the system box.
5. Insert the CF card into the socket, pressing firmly until the card release button is fully extended.
6. Replace the system cover and box.
7. Reconnect the power cord and any external devices, then turn on the system. The system should
automatically recognize the CF card when the system power is turned on.
NOTE: CF card and 2.5 inch HDD master/slave setting:
The system allows the use of both the CF card and hard disk at the same time,
however the user will need to set the system BIOS for the preferred boot order.
When either a CF card only or 2.5 inch hard disk only is installed, the BIOS will
automatically designate it as the 'master' drive and system boot device.
