Abstract
An interlock system is provided that limits the ability of a user or seismic event to dislodge or partially remove more than one chassis from a rack at any one time. Thus, embodiments reduce the potential for the rack to be toppled by the weight of too many chassis extending from the rack at the same time. The interlock system includes a dynamic rail with locking blocks that move to engage hooks on the rear of the chassis. A trigger at each chassis slot is depressed with installation of a chassis. Upon the removal of any chassis, the associated trigger extends and causes the dynamic rail to be pulled down into a locking position in which the locking blocks engage the hooks on the remaining chassis, which prevents their removal.
