Connectors

16) SMB Connector (5-1 pin SMB)

This connector allows you to connect SMBus (System Management Bus) de-
vices. 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.

17) USB Header (10-1 pin USB2)

If the USB Ports on the back panels are inadequate, a USB header is available
for two additional USB ports. Connect the 10-1 pin ribbon cable from the pro-
vided 2-port USB connector set to the midboard 10-1 pin USB header and mount
the USB connector set to an open slot on your chassis.

NOTE: To use this header, make sure that the jumpers (see Motherboard Set-
tings, BIOS) are set to USB Connect.
