Header J6D1 is used to implement the Wake on LAN feature Connect this header to a network interface card NIC that supports the Wake on LAN technology The NIC monitors network traffic When the NIC detects a Magic Packet it asserts a signal through the Wake on LAN header to wake up the computer This signal can wake up the computer only when the power cord is still plugged into the socket and the computer is turned off Wake on LAN can be enabled through the BIOS Setup program gt NOTE The computer s power supply must provide sufficient 5 VSB current to the NIC without enough 5 VSB current the Wake on LAN feature will not function and the motherboard may not boot Check the NIC s documentation for its 5 VSB current requirements See Section 1 22 for information on the motherboard s power requirements 1 14 Wake on Modem The Wake on Modem feature allows the computer to wake from Sleep mode when a call is received on a telephony device such as a modem The first incoming call will power up the motherboard but a second call must be made to access the computer 29 DK440LX Motherboard Technical Product Specification 1 15 SCSI Subsystem The onboard SCSI subsystem features the Adaptec AIC 7895 which contains a dual channel SCSI controller and a PCI bus master interface The AIC 7895 supports the following Narrow 8 bit 50 pin or Wide 16 bit 68 pin Fast SCSI providing 10 20 MB sec throughput per channel Narrow
