Remote Lan Wakeup - SMC Networks 1255TX User Manual

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, 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 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.
