Equipment Racking & Power Protection

All network and control components are installed within custom racks. These racks are pre-engineered for efficient cable management, serviceability, and ventilation.

Each rack includes an online UPS system providing clean, regulated power to connected devices, reducing the risk of voltage fluctuations and power loss. IP-controlled power distribution units (PDUs) allow remote equipment reboot and power cycle management.

Thermal monitoring is achieved via Crestron temperature and humidity sensors integrated into the control system. Threshold alerts are configured to trigger warnings and automated shutdowns in the event of overheating.
