AlphaServers have interlock switches to prevent the system from running while the chassis is open. When the chassis is open, so are the switches, and power is cut to the system. Some AlphaServers, like the ES40, have multiple access panels in the chassis; on these systems, only certain panels being open may cause the computer to shut off, whereas others may just cause it to complain on the control panel. Some AlphaServers can have a jumper set on the mainboard that causes them to remain powered on even if the chassis is open. Some AlphaServers, like the 2100, are finicky, and their interlock switches might still be open even if the chassis is closed - try tightening the panel screws or jiggling the chassis panels a little.
