Exemplary embodiments are directed to cable management plate assemblies for a media patching system or a rack. The cable management plate assemblies include a lower cable management plate and an upper cable management plate. The upper cable management plate can be slidably secured to the lower cable management plate. In a first configuration, the upper cable management plate is disposed in a retracted position relative to the lower cable management plate. In a second configuration, the upper cable management plate is disposed in an extended position relative to the lower cable management plate. Embodiments are also directed to methods of supporting one or more cables in a media patching system or a rack, and associated media patching systems.
