Abstract

Described in this article is a hinge-down front cover for rack-mounted units to allow front service and customer access without breaking electrical continuity within the unit or disturbing other units in the rack. The design is contained within the profile of the external cover. Anti-tilt devices and unit sliders in the rack are unnecessary. The cover can be opened with one hand but remains attached to the rack below the cavity base level for easy withdrawal of a unit. The inside of the cover can contain control panels for servicing use connected to the unit by tape cables compliant with hinge movement. Fig. 1 shows the construction of the right hand side hinge assembly viewed from the front of the rack with the front cover. A steel angle bracket 1 with a vertical slot 2 is secured to the edge of the rack 3.
