ESD Warning
Electronic components and circuits are sensitive to ElectroStatic Discharge (ESD). When handling any circuit board assemblies including Connect Tech COM Express carrier assemblies, it is recommended that ESD safety precautions be observed. ESD safe best practices include, but are not limited to:
- Leaving circuit boards in their antistatic packaging until they are ready to be installed.
- Using a grounded wrist strap when handling circuit boards, at a minimum you should touch a grounded metal object to dissipate any static charge that may be present on you.
- Only handling circuit boards in ESD safe areas, which may include ESD floor and table mats, wrist strap stations and ESD safe lab coats.
- Avoiding handling circuit boards in carpeted areas.
- Try to handle the board by the edges, avoiding contact with components.

TYPICAL INSTALLATION
- Ensure the host system is powered off.
- Insert the M.2 GbE into a 2230 Key A or E card slot; secure the card down with a screw.
- Attach a CBG383 (RJ-45 to Picoblade) cable or custom cabling solution to P1.
- Attach a network RJ46 Cat -5e or Cat 6 cable connected to your network to the CBG383 cable
- Power on the system.
- Under Linux, use lspci to verify the presence on the M.2 GbE, then using ifconfig to verify the
M.2 GbE Card is enumerated as a network interface.
THERMAL DETIALS
The M.2 GbE card has an operating temperature range on -40°C to +85°C, however, it is important that’s adequate cooling is provided to ensure reliable operation. It is the customer’s responsibility to design their system such that the ambient temperature and airflow is within specifications for the Intel® Ethernet Controller I210-AT.
The table below illustrates simulation data from Intel®, this is just a guideline but should be taken into account by system designers. The table lists Tcase as a function of airflow and ambient temperature. This table can be used as an aid in determining a starting point for the optimum airflow for the I210.
Note that Connect Tech does not recommend use with zero airflow at ambient temperatures over 65°C. From internal testing, it was found that at a full 1Gbps load as the ambient temperatures approach ~70°C the Tcase will exceed 100°C.
Table 13-14. Thermal Simulation Results for Various Environmental Conditions
Note: The red value(s) indicate airflow/ambient combinations that exceed the allowable case temperature.
