SMART Embedded Computing PCIE-7217 Installation And Use Manual page 50

Hardware Preparation and Installation
NOTE: If the shelf is exposed to temperatures above room temperature while
operating, SMART EC recommends that slot filler cards are installed in all
unused PCIe slots. PCIe filler cards for the MaxCore shelf are available from
SMART EC.
Make sure that the card has enough air flow after closing the system cover.
Refer to the Cooling Subsystem section of the MC4100 Shelf Installation
and Use manual.
The CPU transcoding performance is directly related to the airflow and
cooling ability of the server in which the card is installed.
8. Connect your system to the console microUSB port of the PCIE-7217 card using a
standard USB-A to microUSB-B cable.
The PCIE-7217 face plate contains a microUSB 2.0 host port per CPU and a
microUSB terminal port to access the serial console (COM port) for both CPUs.
Each of the USB host ports is connected to one of two CPUs (USB1 for CPU1 and
USB2 for CPU2). With appropriate USB adapters for various devices, the USB1 and
USB2 ports are available to connect standard USB devices like flash drives to the
CPUs.
For terminal connections, a single console microUSB port is available for both
CPUs. For a host to access the serial console ports of the CPUs through the console
USB port, a cp210X driver must be installed on the host system. The cp210x driver
is available at

The standard USB-A to microUSB-B cable is also available from SMART EC
(Ordering P/N MC3000-I/O-USB-CBL).
