And next we discover three standard data connectors for SATA cables and a row of pins for signal cables indicating the HDD ready status, activity or failure (some nice controller cards have signal outputs like that), and a three-phase switch. As the installation guide suggests, this switch sets the temperature threshold. Once this threshold is reached, the module will send the “overheating” signal to the front panel. You have three choices for the threshold: 45, 55 and 65oC. The default switch setting was 55oC, however, I felt better when I moved it down to 45oC.

It is important to know that the alarm sound can be shut down from the front panel of the module by pressing the Reset button.

When we extract the HDD slides from the chassis, we find a transportation cross-piece inside:

You will have to remove the cross-piece before installing the hard disk drive into the slides. At the bottom of the slides there is a spring mechanism that helps absorb the vibrations that may occur during the HDD operation.

Inside the chassis there is nothing interesting: three SATA connectors and a hardly visible thermal sensor (in fact the thermal monitoring is based not on the actual HDD temperature, but on the temperature of the airflow going through the chassis).
