or in the field by a technician.
Expansion cards are designed to fit in one of two expansion slots accessed from the unit's front or back
panels. In general, cards with antenna interfaces, such as the WLAN card, are installed in the back slot to
avoid interference with the 3G antennas on the front of the base unit.
Tip: Another way to determine the appropriate slot, is to look at the card connector. Cards with the
small connector are installed in the rear slot. Cards with the large connector are installed in the front
slot.
To install an expansion card:
1. Make sure the unit is powered off.
2. Using a T6 Torx screwdriver, remove the three screws from the bottom plate on the front or
back panel, and remove the plate.
3. With the expansion card in your hand, make sure the English labelling for any external
interfaces, such WLAN Antenna or Serial Port, are facing up. In this orientation, the card
connector is also right facing.
