D. COM Module Installation
There are two options for COM module installation: Via the I/O (default); via the
expansion slot. Both methods of installation are explained below.
D.1 Via the I/O
1.
Follow Steps 1 ~ 3 of Subsection A.
2.
Retrieve the two COM connectors from the module case and affix them to the
I/O shield at the side of the device using two screws. Then connect the COM
cables to the mainboard and secure with a cable tie (see Fig. 2.53).
3.
Replace the VESA mount plate (as shown in Fig. 2.54) and secure in place
using four screws. Then replace the rear cover to complete the installation.
