Expansion Card Insertion Procedures
The T850-2 and T850-6 models can be purchased with a variety of optional Expansion Cards that are normally
inserted in the expansion bays on the back panel of the unit when it is built at the factory. These Cards can also be
purchased separately and inserted by field technicians after the unit has been installed in the field. When doing this,
there are some specific precautions and steps that must be followed in a specific order when inserting Expansion
Cards in the field:
The field technician must take precautions to ensure he/she is electrically grounded so as not to damage the
Expansion Card circuit board, or the main circuit board of the unit. Follow normal Electrostatic Discharge
(ESD) procedures for handling electronics per IPC-610.
The Expansion Card should remain in its protective ESD bag until it is time to actually insert it into the
expansion bay.
Follow these steps to install an Expansion Card:
1. Unplug the power cable from the T850. Expansion Cards are NOT hot-swappable.
2. Unplug the telephone cord from the internal modem (if connected). This MUST be done before removing any
expansion port cover plates.
3. Remove the two screws for any expansion bay cover plate and set the plate aside.
4. Carefully remove the Expansion Card from its protective ESD bag and slide it into the plastic rails inside the
expansion bay. Visually confirm that the Card is in both rails and properly aligned.
5. Push the card until it is fully inserted in its slot.
6. Replace the two screws previously removed so the Card is held securely in the bay.
7. Place the Expansion Card label on the back panel directly above or below the Expansion Card, taking care to
align the markings on the label with appropriate I/O points or ports on the Card.
Note:
If installing a Wireless Modem Expansion Card, attach an antenna to the SMA connector. (An antenna
such as the MobilMark RMA3-900/1900 or equivalent is recommended). A rubber GSM antenna is included for a
convenient interim antenna. This can be screwed on to the SMA connector for trial. The unit should not be
powered up without an antenna connected to the modem.
8. Replace the telephone cord in the internal modem jack (if used).
9. Plug the power cable into the host unit.
10. After the unit reboots, proceed with connecting devices to, and configuring the Expansion Card, as necessary
for the type of Card it is.
