Smart cooling and Alarm functions

MCU Cooling monitoring System

Rocpro U34 is designed with the MCU feature which monitors and helps improving its in-chassis system temperature. If the system temperature rises up due to drive usage, MCU will increases the fan speed to full speed and the Alarm will sound. Users can manually adjust the fan speed by switching it On in the rear of the storage unit. MCU would reduce the fan speed down to SMART speed for a better green usage environment, less fan noise and lower power consumption.

In addition, if the fan fails or the device temperature is too high, the buzzer will beep and let the user know the status of the fan. The user can turn off or turn on the buzzer through the mute adjustment switch on the back panel.
