This is a 4-pin connector for a 5V fan. J2 can be configured in the BIOS
setup. See Section 6.2, “Onboard Fan Connector” for more detailed
information.
4.4 Signal Descriptions
4.4.1 PCI Express Interface
The PCI Express* x1 lane is a fast connection interface for many different
system devices, such as network controllers, I/O controllers or express card
devices. The implementation of this subsystem complies with the COM Express™
specification. Refer to the PICMG COM Express™ Design Guide for additional
implementation information.
The ETXexpress®-AI COM supports up to 7 PCI Express x1 lanes. See Table 11
and Table 12 for detailed configuration information.
