13) SMBus 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

I
C 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.

14) Digital LCD Header (20-pin DFP)
This optional header requires a digital LCD cable connector. Connect the digi-
tal LCD cable to this header and mount the bracket to the chassis on a free
expansion slot. NOTE: If both CRT and digital LCD monitors are used, the
CRT will take precedence. This connector is for a digital LCD panel; an analog
LCD panel comes with a 15-pin VGA cable connector to be used on the moni-
tor connector. The connector with bracket shown here is provided with the LCD
model.
