Remote LAN Wakeup
Remote LAN Wakeup capability is a key feature of a centrally managed PC environment. This
technology enables networked PCs to be "woken up" from a sleep or powered-off state so they
can be managed from a central location, at any time of the day or night.
To employ Remote LAN Wakeup, four 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 net-
work card when the PC is powered off.
• A Wake-On-LAN network card that can recognise a wake-up packet and signal the PC to
power up.
• The Wake-On-LAN cable must be connected to the 10/100 Mbps Network Card and to the
motherboard of your computer.
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 a ground.
Even if the PC is powered off, the 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.
