MCU feature to provide you in-chassis temperature control
SR4-TB2 is also designed with the MCU feature which monitors and helps improving its in-chassis system temperature. While the system temperature rises up to 50 degree-C (118 degree-F), MCU will bump up the 8 cm fans with full speed; and once system temperature goes down to 45 degree-C (109 degree-F), you could manually adjust fan switch on the rear, MCU would reduce the fan speed down to a half speed for a better green user environment from a less fan noise and lower power consumption.
The built-in power supply unit
SR4-TB2 uses conform with safety regulation certified 200W power supply unit which provides a stable and high efficient power output and definitely satisfies the big power consumption from all 4 HDDs.

2. When the computer enters hibernation mode, the fan and power status lights will both be in stopped/ hibernation mode. The fan and power status light will not come on until the computer is awake.
3. If a hard disk already contains data from another RAID product or RAID mode has already been set, we recommend reverting back to JBOD mode before the drive is used with the SR4-TB2 again to avoid problems accessing the hard drive.
