-====== Sensors ====== 
- 
-Each Baseboard of the RECS 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 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.

-===== 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. 
- 
-^ Temperature ^ Type  ^ Left ^ Right ^ 
-| Inlet | CXP | 1 | 3 | 
-| ::: | APLS | 1, 2 | 3, 4 | 
-| Outlet | CXP | 3 | 1 |
