8-2 Sun Fire V120 and Netra 120 Server User’s Guide • December 2001
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).
