5.4 3G Installation Overview & Safety Information
The following sections present general installation and removal procedures that are required to install a 3G modem in
the M2M system.
Overview
To install the 3G modem you will need to remove the chassis cover, remove one of the system boards and a spacer
piece, attach and install the modem and then reinstall the board previously removed. Then you must reattach the
chassis cover. The spacer piece is not reinstalled.
Safety Information
The Kontron M2M System must be operated with the covers in place to ensure proper cooling. You will need to
remove the front cover to add or replace components inside the chassis.
CAUTION: The system must be disconnected from the power supply when adding components. Before
removing either the mounting bracket or front cover, power down the Kontron M2M System by
unplugging it from the wall outlet.
A non-skid surface or a stop behind the Kontron M2M Smart Services Developer Kit may be needed to prevent the
Kontron M2M System from sliding on your work surface.
1. Observe the safety and ESD precautions in Appendix A.
2. Turn off all peripheral devices connected to the Kontron M2M System.
3. Disconnect the power cord(s) to turn off the Kontron M2M System.
5.5 Removing the Chassis Cover
The first step is to unscrew the chassis covers (5 total: 2 on top, 2 on bottom and 1 on side near audio jacks). Retain
all screws for reassembly. The cover will not lift off since it is attached to the large panel without the label.
Figures 18-20 show the start of removing the chassis cover.
