Wake on LAN
For the Wake on LAN (WOL) feature to operate properly, the NC3123 Server Adapter must be
connected to a continuous power source. This allows the adapter to listen to the network even
when the computer is powered off.
The WOL feature lets designers build adapters that can “listen to” network activity even when
the computer is powered off. WOL adapters have a special low-power standby mode that is
active when the rest of the computer is without power. The adapter will respond to a special
“wake-up” packet sent by another computer or network device. Typically this wake-up packet
causes the adapter to signal the computer to power up.
See “Connecting the Wake on LAN (WOL) Power Cable” in Chapter 2.
On or flashing The NC3123 adapter is receiving direct packets or broadcast packets for this
specific adapter. When sending packets, the ACT light is also active due to
network acknowledgments being received.
Off The NC3123 adapter is not receiving direct packets or broadcast packets.
