Extensive resources can be required to stage, clean-and-screen, repair, diagnose, etc. a network device. To reduce the impact on resources, a diagnostic device is used to perform diagnostic testing or analysis of a network device, such as a set top box received at a facility. The diagnostic device connects to the network device via one or more connections to initiate a diagnostic testing and analysis. The network device sends diagnostic data to the diagnostic device which uses this data to generate a diagnostic report and/or sends this data to a network resource. The diagnostic testing or analysis is used to appropriately direct the network device, for example, for repair, redistribution, disposal, or other treatment.
