21) USB Headers (10-1-pin USB56)
If the USB ports on the back panels are inadequate, one USB header is
available for two additional USB ports. Connect the 10-1 pin ribbon cable from
the provided 2-port USB connector set to the two midboard 10-1 pin USB header
and mount the USB connector set to an open slot on your chassis.
22) SMB Connector (5-1 pin SMB)
This connector allows you to attach SMBus (System Management Bus) devices.
SMBus devices communicate by means of the SMBus with an SMBus host and/
or other SMBus devices. SMBus is a specific implementation of an I2C bus,
which is a multi-device bus; that is, multiple chips can be connected to the same
bus and each one can act as a master by initiating data transfer.
