The memory is on the carrier? Not the ComExpress Module? That seems
wrong. If you look at the Congatec COM Express Type 7 Modules, they
all have a socket for the memory. Which ComExpress connector is used
for the memory between the Module and the Carrier?

Just for my understanding....

This is the 1G Ethernet on the A connector. And the PHY is on the
module, not the carrier?
I just wanted to check because the 4x 10G PHY are -KR, not copper, so
the PHYs would be on the carrier.
