J46: WOL Connector
Function
This connector lets you attach a managed network adapter to the
motherboard via a Wake-on-LAN cable. When the system is off, the
managed network adapter uses an alternate power source to monitor
the network. If it receives a wake-up packet from the server the
system is remotely and automatically powered up.
J48: SMBus Connector
Function
The SMBus (System Management Bus) connector is used to con-
nect SMBus devices. It is a multiple device bus that allows multiple
chips to connect to the same bus and enable each one to act as a
master by initiating data transfer.
