8.1 Introduction to Lights-Out Management
The system board in the Sun Fire V120 and Netra 120 servers contains a LOM device
(see
FIGURE 8-1). This device provides management facilities that enable you to detect
and respond quickly to problems. The facilities are particularly useful for managing
servers that are deployed in a “lights out” environment. However, you can also use
them to perform quick onsite management tasks at a locally connected terminal.
You can use the LOM facilities remotely or from a local connection to:
Power the server on or down to standby mode.
Monitor the server’s temperature and the status of its power supply, fans, supply
rails, fault LED and alarms, even when the server is in standby mode.
Turn a Fault LED on.
Configure the server to restart automatically after a lockup (see Chapter 9).
