Service shelf for electronic cabinet

A system for facilitating access to electronic modules within an enclosure having multiple vertically stacked levels of module storage locations, the system comprising:

• a shelf device that includes:
• a pair of support arms each having
• an attachment structure on a distal portion of the support arm that is designed to attach to a first one of the vertically stacked levels;
• a horizontal support platform extending from the distal portion of the support arm toward a proximal portion of the support arm and that, while the support arms are attached to one of the vertically stacked levels, is designed to support weight of an electronic module by providing a horizontal surface upon which a bottom of the electronic module can rest as the electronic module is moved from the distal portion of the support arm and toward the proximal portion of the support arm;
• a vertical guide rail extending perpendicular to support platform from the distal portion of the support arm toward the proximal portion of the support arm and that, while the support arms are attached to one of the vertically stacked levels, is designed to guide movement of the electronic module toward the proximal portion of the support arm by inhibiting lateral movement of a side of the electronic module as the electronic module is moved from the distal portion of the support arm and toward the proximal portion of the support arm along the support platform;
• a cross brace structure pivotally attached to distal portions of the pair of support arms and a proximal portion of a first one of the support arms and having a locking connection structure that is designed to attach to a proximal portion of a second one of the support arms;
• and
• a pair of vertical braces each pivotally attached to a respective one of the pair of support arms and having a detachable connection structure that is designed to attach to a second one of the vertically stacked levels.
