Remote LAN Wakeup
Remote LAN Wakeup capability is a key feature of a centrally
managed PC environment. This technology allows networked
PCs to be powered up and managed from a central location,
at any time of the day or night.
To employ Remote LAN Wakeup, three elements are required:
Desktop management software that can send a “wake-up”
packet to a PC.
A Wake-On-LAN enabled PC motherboard that can supply
low-level auxiliary power to a network card when the PC is
powered off.
A Wake-On-LAN network card that can recognize a wake-
up packet and signal the PC to power up.
A Wake-On-LAN enabled PC is never completely powered off,
it maintains a low-level auxiliary power supply to the
motherboard. The 3-wire Wake-On-LAN cable provides one
line for the network card auxiliary power and one line for the
card wake-up signal, the other line is ground. Even if the PC is
powered off network card is always active and monitoring the
network. When a wake-up packet is detected, the card signals
the motherboard to power up the PC. With the PC powered on,
maintenance and other support tasks can be performed.
