-====== Sensors ====== 
- 
-Each Baseboard of the RECS<sup>(r)</sup>%%|%%Box system includes five temperature sensors that are regularly polled by the management software. This data is available in raw format via all [[Software interface|software interfaces]] provided by the TOR Master. Additionally, the TOR Master calculates some derived temperatures: Inlet- and outlet temperature (Arneb only) as well as the highest temperatures on baseboard, RCU and cluster level. 
- 
-===== Locations ===== 
- 
-The following pictures indicate the location of the various temperature sensors on the baseboards along with their indices in the management data. The golden finger contacts on the right side of the picture always point towards the backplane.

-Please note that temperature sensor 1 on the ARM baseboard (near the four fan connectors) is somehow thermally connected to the voltage regulators (located between the four fan connectors). This results in high temperature of this sensor if the modules 1 and 2 are powered on and consuming a lot of electrical power.

-===== Assignment ===== 
- 
-Depending on baseboard type and location, the Arneb RCU calculates inlet- and outlet temperature for each baseboards by averaging different temperature sensor readings. The following table shows which sensor(s) are used, where "left" and "right" are seen as looking onto the LCD of the unit. \\
