What You Can Use the ‘Lights-Out’
Management (LOM) Facility For
The Netra t1 includes a management facility which allows you to detect and respond
quickly to problems with the Power Supply Unit (PSU) or fans. It is particularly
useful for monitoring servers remotely that are deployed in a “lights out”
environment. But you can also use it to perform quick onsite management tasks via
a local serial connection.
This management facility is provided by a device on the Netra t1’s motherboard
called the Lights-Out Management (LOM) device and by software that is pre-
installed on your system during manufacturing.
Note – If you install new system software onto the Netra t1 and you want to
continue using the Lights-Out Management facility, you must re-install the LOM
software. A CD containing the software is available from your Sun Enterprise
Services representative (part number: X6972A).
You can use the LOM facility to:
■
Monitor the status of the power supply, fans, fault LED and alarms even when the
system is powered down.
■
Power the system up and down.
■
Turn a Fault LED on (for example, to enable you to identify a particular system in
a rack containing a number of Netra t1s).
You can also configure the LOM device on the Netra t1 to perform an automatic
system restart in the event of a lock-up.
