+ | ==== Power connectors ==== | ||
+ | |||
+ | === Antares === | ||
+ | |||
+ | The Antares has one male C14 jack on the back that can be connected to an 230V power outlet using a standard C13 cable. Both built in power supplies are connected to this jack.\\ | ||
+ | The exhaust air openings in the back must be kept free. Keep that in mind when installing cables behind the Antares. | ||
+ | |||
+ | === Arneb === | ||
+ | |||
+ | The Arneb has six 12V power connectors on the back. These are connected to an Alasco power supply. The upper male plug is the (+) pin and the bottom female plug is the (-) pin. All six connectors are joined together to two copper rails. One (+) and one (-). The plugs are coded and can only be plugged in in the right way.\\ | ||
+ | How many of these connections to the Alasco are needed depends on the hardware configuration and the total power consumption of the Arneb. | ||

+ | ==== Power connectors ==== | ||
+ | |||
+ | The Alasco has one male C19 jack on the back that can be connected to an 230V power outlet using a C20 cable. Connect this cable to an 16A fuse, as the Alasco can require up to 3600W.\\ | ||
+ | There are nine 12V plugs in the back, that can be connected to one or more Arneb****s via the coded connectors. The upper male plug is the (-) pin and the bottom female plug is the (+) pin. | ||

+ | |||
+ | ==== 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. | ||

+ | |||
+ | <WRAP center round info 60%> | ||
+ | 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 " | ||
