Advanced Lights Out Management on Sun-Fire 280R, V480, V490, V880, V890, and Sun Enterprise 250

This group of work group servers have a feature called "Advanced Lights Out Manager (ALOM)".

The ALOM feature on servers like the V490 is enabled through a "System Card (SC)" which even offers a windows GUI through the "Sun Remote System Control (RSC)"
The "Sun-Fire V490 Server Administration Guide" covers features with the System Card, basic setup, and basic usage
    (Pages: 22,33-35,54-55,72,73-78,83-84,99,101-102,122,125,141,159-161,168-169,172,175,181-182,190-197)

Specific case usage is covered in the "Sun Remote System Control (RSC) 2.2 User’s Guide"
The latest version of the software is 2.3.3, installation examples can be seen here.
You can check to see if a platform appears to have an ALOM card installed.
  • {system}/{user}$ prtfru -x | nawk '/Container name="rsc-board"/,/Container> /'
You can check to see if supplemental OS software is installed on this server.
  • {system}/{user}$ /usr/bin/pkginfo | grep SUNWrsc
By attaching to the ALOM on the SC through the RSC GUI, TCP/IP telnet/ssh, serial terminal server, or even dial-up modem - support staff has access to OpenBoot Firmware on the platform before the boot, can initiate alternate boots, enable debugging, completely power off & on the entire chassis, and even disable failed components (like memory chips) on some models remotely.
