Xserve had LOM hardware 20 years ago.

  LOM enables power management even if the Xserve is off, and even if it lacks an installed operating system.

Edit: Xserve was an Apple rack mounted server that ran a special version of Mac OS X

This isn’t quite lights-out, and Xserve ran the same version of Mac OS X Server you could install on any other Mac.

How is it not lights-out? You could remotely power on/off the servers (XServe only). Other Macs could not do this, as they did not have the separate LOM network interfaces, etc.

I managed a bunch of XServes for a while, they were incredibly good hardware. The Mac Server software kinda sucked (not the LOM stuff, it was as good as any of the LOM from Dell, which is to say, not amazing, but workable).

Sorry, I was referring to the automatic power-on feature described in the linked article.

Only on the Xeon models. The G4 and G5 didn't have any kind of LOM :(

My original comment was to add context to the article's first line:

  Apple FINALLY lets you turn on your Mac remotely, without having to press the power button.

To you and me, that sentence needs the word "again" appended to it.

To be fair, the number of users who ever touched an Intel Xserve is infinitesimally small in comparison to other Macs.

[thomassmith65]

Any implication that OS X Server could only run on Xserve was inadvertent. I mentioned the special OS to preempt discussion of whether Xserve was, strictly speaking, part of the Mac product line.

[dcrazy]

Xserve is a Mac. In fact the original one’s product code was RackMac1,1.

Well then, the Mac had LOM hardware 20 years ago.
