This project required the fabrication and deployment of a 42U primary core rack designed to serve a multi-floor corporate headquarters. The system needed to handle over 120 individual Dante audio endpoints, complete centralized DSP routing, and a massive Video-over-IP (VoIP) switching matrix.
The primary hurdle was extreme density. With four high-output amplifiers and two heavily loaded network switches in a single rack, thermal management was a critical concern. Furthermore, the client mandated a zero-tolerance policy for signal interference, requiring strict physical separation of high-voltage power lines and low-voltage CAT6a control networks.
To combat thermal throttling, I engineered custom blanking panels and utilized active exhaust units at the top of the rack to create a forced-air chimney effect. For cable management, I implemented customized rear lacing bars. All 120V power was dressed rigidly down the left vertical channel, while all Dante, control, and video signals were dressed on the right, utilizing custom velcro spacing intervals to eliminate crosstalk and maintain the pristine noise floor required for the DSP matrix.
