Lights-Out Management (LOM)
Definition - What does Lights-Out Management (LOM) mean?
Techopedia explains Lights-Out Management (LOM)
Although some hardware pieces like computers may need a management card, many servers provide built-in remote management that makes LOM easier. System administrators, for example, may plug a rollover cable into a dedicated LOM port in the server to connect it to the remote management system.
Lights-out management addresses the "humans plus hardware" problem — the issue of the resources that humans need to work with vs. the optimal environment for servers. A number of companies have developed dedicated server and hardware rooms with specific cooling solutions, to keep hardware at an optimal temperature and atmosphere. Lights-out management gives business leaders another option for deploying resources.
