What ALOM Monitors
TABLE 2-1 lists some of the components that ALOM can monitor on the server.
Note – While redundant power sources are desirable, if only one DC connector is
supplying power to the DC-powered version of the server, ALOM might
occasionally report the following message:
SC Alert: env_log_event unsupported event
Using ALOM
The ALOM software is supplied ready-to-use and can support multiple users.
However, only one user at a time can issue any commands that require write
permissions. The other users can only issue read-only commands.
There are two ways to connect to ALOM:
■ Use the telnet command to connect to ALOM through the Ethernet connection
attached to the NET MGT port.
■ Connect a serial device, such as an ASCII terminal or a port on a terminal server,
to the SERIAL MGT port.
