Define E-Stop Requirements The computer system power panel should include a shunt-trip wired to an emergency shut-off switch and a thermostat device. Electrical codes commonly stipulate that this button will remove both power AND airflow from the computer room. This is for deactivating all equipment power in case of an emergency or in case room temperature exceeds safe operating conditions. Check the local electrical codes to see whether the E-stop switch is optional or required. 29
