One aspect of the instant application provides an apparatus for locking a circuit board in position. The apparatus can include a cam latch, a plunger, and a hinge pin coupling the cam latch and the plunger. The cam latch is positioned to rotate around the hinge pin, and the rotation of the cam latch causes a linear motion of the plunger in a plane parallel to a component-mounting surface of the circuit board, thereby facilitating locking and unlocking of the circuit board.

In one aspect, a bracket assembly comprises a bracket and a pair of rails. The bracket comprises a first portion which includes a first segment with a first opening and a second segment with a second opening. The pair of rails comprises: a first rail which includes a first tab protruding from the first rail and including a first notch; and a second rail which includes a second tab protruding from the second rail and including a second notch. The bracket is to attach to the pair of rails when: the first portion is placed against the ends of the rails such that the first tab is inserted into the first opening and the second tab is inserted into the second opening; and the bracket is slid down such that the first opening rests in the first notch and the second opening rests in the second notch.

One aspect provides an apparatus for locking circuit boards in position between a pair of guide rails. The apparatus can include a slider attached to a sidewall of one guide rail. The slider is allowed to slide along the guide rail within a predetermined range and one or more plunger-and-spring assemblies. A respective plunger-and-spring assembly comprises a plunger and a spring surrounding the plunger, and the plunger is inserted into a through-hole on the sidewall of the guide rail such that a first end of the plunger can be aligned with a notch on a corresponding circuit board and a second end of the plunger is in contact with the slider. Sliding of the slider causes the spring to compress and decompress and the first end of the plunger to move in and out of the notch on the circuit board, thereby facilitating locking and unlocking of the circuit board.

Examples include comparison of a part key to machine keys. Examples include identification of a part key assigned to a given machine identifier in a part key mapping of a part received by a computing device, the part key mapping including a plurality of part keys assigned to a plurality of machine identifiers. Examples also include comparison of the identified part key to machine keys stored on the computing device to determine whether the identified part key matches any of the machine keys, and based at least in part on a result of the determination, enabling or inhibiting further utilization of the part.
