Abstract: A rack mountable shelf supports a plurality of field replaceable units (FRUs) in the form of server cartridges, or blades. The blades are provided with an enclosure that includes a metal portion and a plastics portion. The provision of a blade enclosure for the blade can protect the components of the blade from physical damage and can also isolate them from electrical, static and other effects that could be potentially damaging to the blade components. The use of metal can provide strength and electromagnetic interference shielding with a very thin layer. The use of plastics can provide lightness, flexibilty in design, and the avoidance of metal to metal contact to facilitate insertion and removal of the blades.

Abstract: An enclosure to control access to a selected portion of an enclosed electronic device is provided. The enclosure includes a plurality of access panels that are capable of being fastened in a secure position via a single fastener mechanism. The fastener mechanism is operable by an authorized individual. The fastener mechanism controls when each of the plurality of faceplates can be disengaged from the enclosure to access a portion of the electronic device.

Abstract: An ejector mechanism is provided for a field replaceable module (e.g., a server blade) of modular computer system (e.g., a blade server system). The field replaceable module can be received in a carrier of the modular computer system and can have an elongate face. An ejector mechanism, that can possibly also act as an injection mechanism, can be located at the elongate face and can include an elongate lever extending substantially along the elongate front face. A pivotal mounting for the lever can be located towards a first end thereof and an ejection protrusion can be provided at the first end. The use of a lever that extends substantially along the elongate face of the field replaceable module provides an efficient ejection mechanism with good mechanical advantage.
