5 Hardware details
5.1 PCI Express
The emPC-CXR uses PCI Express for a couple of expansion options. Some COM Express modules
only provide a limited number of PCI Express lanes. Refer to Table 9 for a detailed resource list.

5.2 Ethernet
The emPC-CXR provides two 10/100/1000 ethernet interfaces
5.2.1 LAN1
This Ethernet interface is provides by the COM Express module, refer to the module documentation
for details (e.g. controller type).
Wake on LAN implementation depends on the COM Express modules and is usually possible.
5.2.2 LAN2
This Ethernet interface is implanted on the carrier board by an Intel i210 ethernet controller.
The standard configurati
on uses the i210’s iNVM memory for parameter storage. As an option,
external FLASH memory option is possible, but not normally equipped on the carrier board.
Wake on LAN is not supported by Ethernet 2.
