Once we suffered a mismanaged tagging# blues of our servers in one of the data center. Reboot request sometimes rebooted a wrong server. Now imagine if that server was serving live -that too business critical traffic! Well, preferring NOT to explain the post episode here. Now any guess how do we make it sure that the DC engineer is actually standing in front of the right server, if he had a reboot request to address a server hang or server shifting etc.? :-)
Yes! You are right - 'e' for eject was the savior that time. If he is close by somewhere in the grid or rack one eject should be enough and if it is NOT visible to him - get some scripting in place!

#pull CDROM tray back in
He will definitely locate your server, believe me!
Knock Knock!! Now who says disabling/removing CD-ROM from my server should be a part of DC physical security checklist!!?
