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
(with PCI 2.2) 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. 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.
