> What exaclty is an "anti-tip feature"?

Most racks have a pull out stabilizer of some kind, or even jutting out little "feet" to prevent them> from tipping over forwards while you pull heavy things out on the rails. So, in order to pull out a device, first you pull out the anti-tip bar at the bottom, then pull out the device. The DEC H960 racks don't have that pull-out bar, instead they have two feet that stick out the front of the cabinet a foot or so, and serve to trip people walking too close to the computer... -Ian
