Alert on LAN
# Alert on LAN

Alert on LAN (AOL, sometimes AoL) is a 1998, IBM- and Intel-developed technology that allows for remote management and control of networked PCs. AOL requires a Wake on LAN adapter.

## Technical details

The main idea of AOL is to send warnings to remote administrators about different PC conditions using a LAN. These conditions include:

* System unplugged from power source
* System unplugged from network
* Chassis intrusion
* Processor removal
* System environmental errors
* High temperature
* Fan speed
* Voltage fluctuations
* Operating system errors
* System power-on errors
* System is hung
* Component failure

Alert on LAN 2 (AOL2) extends AOL to allow active PC management, including:

* Remote system reboot upon report of a critical failure
* Repair Operating System
* Update BIOS image
* Perform other diagnostic procedures
