lights-out management (LOM)

Lights-out management (LOM) is the ability for a system administrator to monitor and manage servers by remote control. A complete LOM system consists of a hardware component called the LOM module and a program that facilitates the continuous monitoring of variables such as microprocessor temperature and utilization. The program also allows for such remote operations as rebooting, shutdown, troubleshooting, alarm setting, fan-speed control, and operating system reinstallation.

A single LOM system can be used with more than one server without the need for on-site staff at any of the server locations. Communication between the controller and the remote servers can be done through an independent dial-up connection. The LOM module keeps a record of all the operations (known as the event log), allowing the administrator to instantly check any or all of several hundred recent system events.
