I'm a software engineer and our lab usually has several servers in a rack with a KVM switch. We're developers and we usually have several projects happening at once so the servers are frequently imaged and admittedly we aren't good at keeping them labeled, etc.
The point is, up until recently, as soon as we walked up to a terminal it was our habit to use
eject to see which physical server we were actively selecting on the KVM switch, for obvious reasons.
Now we are transitioning into servers without optical drives. So the old
eject trick is obsolete. There must be a simple command to flash the "ID" indicator on the front panel of the computer, but after Googling as many variations of the question as I could think of, I got nothing.
The servers are running Scientific Linux 6.4. Thanks for any help you can offer.
