Lights out management

Launch Server Monitor on the Xserve and click Server > Configure Local Machine
Check to make sure you configuration is correct and matches the configuration you've set on the client monitoring it.

The BMC is the baseboard management console; it's a component of the LOM console interface into the extensible firmware interface (EFI) and low-level hardware environment.

No experience with this particular error, but it likely it means you'll need to power-cycle the box (and leave it unplugged for fifteen or thirty seconds), then (if the box and the LOM comes back) check that the LOM firmware is current, (or if not) then see about swapping the associated (failed) hardware.

You can try using the console-level ipmitool to chat directly with the LOM, but this looks rather like a sick LOM or a sick Xserve box. That the Server Monitor configuration path for the local machine LOM has failed isn't good.

Hi !

I am beginig with Mac OS X Server
I have two questions...

I use ARD (Apple Remote Desktop) in my classroom and i know that ARD can "Power On " all computers, but this function is only for Servers or is possible to Turn it on the computers.

When i try to do, the ARD says "Remote Desktop can only power on computer that support Lights Out Management."

Ok the second questions is, what is exactly Lights Out Management, is a software or hardware, is supported for all Apple computers or only X Server?

I have tried to look for any answer in google but the info is no clear, all links refers to X Server but i don't understand anything!

The 'Power On' function of ARD will only currently work with LOM-enabled XServes. You will not be able to power-on, from a shutdown state, any Intel-based desktop or PowerPC-based Mac.

Welcome.

I use ARD (Apple Remote Desktop) in my classroom and i know that ARD can "Power On " all computers, but this function is only for Servers or is possible to Turn it on the computers.

I'll presume the goal here is a full hardware remote power-down, or a full remote power-up?

When i try to do, the ARD says "Remote Desktop can only power on computer that support Lights Out Management."

While you can shut down boxes remotely, what I expect you're considering here is known by various names including Wake on LAN (WoL). [Here|http://discussions.apple.com/thread.jspa?messageID=9387085] is a discussion of WoL. WoL works fine; toss a Magic Packet at the box, and off the box should boot from sleep (rather than power-off).

Ok the second questions is, what is exactly Lights Out Management, is a software or hardware, is supported for all Apple computers or only X Server?

[TA24506|http://support.apple.com/kb/TA24506] describes the Lights Out Management (LOM), and the LOM hardware is a feature of Xserve servers.

[HT2773|http://support.apple.com/kb/HT2773] describes the LOM configuration process.

LOM is low-level hardware, firmware, and software. The LOM hardware is available as a feature of Xserve servers, and is presently not available in other Mac systems.

I have tried to look for any answer in google but the info is no clear, all links refers to X Server but i don't understand anything!

Understanding is a three-edged sword; wait, whoops, sorry, wrong quote... 🙂 Mac OS X Server has a substantial [documentation set|http://www.apple.com/server/macosx/resources/documentation.html], and the various hardware systems have documentation for the devices. (It's a whole lot of reading, yes, and as we've all discovered. Useful, too.)

ps: Please consider new thread(s) for your questions.
