The second host port (named USB2) can also be configured as a miniPCI Express
®
USB modem interface.
With an USB 2.0 switch the host port supports either the standard connector J24 or the USB modem
interface on connector J27. One I/O line (NVIDIA
®
label: L.05) enables the switching between the
interfaces:
Standard connector J24

The modem card interface is available through the connector J27 (52 pins).
