14) SMBus Connector (8-1 pin SMB)
This connector allows you to connect 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 I
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.
CUR-DLSR SMBus Power Connector
Refer to the following illustration for items 15-23.

15) NIC Activity LED (2-pin)
This shows the status of the NIC through a panel-mounted LED.
16) Status LED (2-pin)
This shows the system status as programmed through the ASIC.
17) System Management Interrupt Lead (2-pin)
This allows the user to manually place the system into a suspend mode or "Green"
mode where system activity will be instantly decreased to save electricity and
expand the life of certain components when the system is not in use. This 2-pin
connector (see the preceding figure) connects to the case-mounted suspend switch.
