Lights-out management

Lights-out management (LOM) is the ability for a system administrator to monitor and manage servers by a LOM remote control program.

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.

The modular chassis, the Brocade VDX 8770-8 and the Brocade VDX 8770-4, have two redundant management modules, MM1 and MM2. Each management module can communicate with each of the line cards (interface modules) through an Ethernet connection. Each management module has two Ethernet interfaces, Eth0 and Eth2. These interfaces are also known as Out of Band (OoB) management interfaces and support LOM programs.
