Alert on LAN
Alert on LAN provides notification of changes in the computer, even when the
computer power is turned off. Working with DMI and Wake on LAN
®
technologies, Alert on LAN helps to manage and monitor the hardware and
software features of the computer. Alert on LAN generates notifications to the
server of these occurrences:
v
Computer disconnected from the network
v
Computer unplugged from the power outlet
v
All POST errors
v
Operating system or POST hang condition
Alert on LAN events are configured to be Enabled or Disabled from the LAN
server only, and not from the computer. See the LAN administrator for
configuration status information.
BIOS levels
An incorrect level of BIOS can cause false errors and unnecessary FRU
replacement. Use the following information to determine the current level of BIOS
installed in the computer, the latest BIOS available for the computer, and where to
obtain the latest level of BIOS.
