-====== RCU interface ====== 
  
-===== Front panel connectors ===== 
- 
-The following items are located at the front of a RECS<sup>(r)</sup>%%|%%Box RCU: 
-  * Two line display 
-  * A five button D-pad 
-  * Four internally switched LAN ports that connect to the 1GbE management network of the nodes 
-  * One LAN port that connects to the internal management controller (marked with "Management") 
-  * Four USB ports that can be switched to every module via KVM 
-  * One HDMI port that can be switched to every module via KVM 
-  * Six (Antares) or 18 (Arneb) LAN ports that connect to the compute network of the labelled node (network speed depends on the installed netboards

-===== Control panel ===== 
- 
-The display on the front panel of the RCU shows the status of the unit on multiple screens that automatically change every couple of seconds and are updated live.

A dash ("-") indicates baseboards that are not populated or where not found. In case of an Antares RCU also the status of the power supplies is shown. "L" and "R" mark the orientation of the display and are shown as looking onto the front panel. |

-The buttons next to the display will be used for a local management menu later on. Currently they are not used except for the "down" button: Press this key for a few seconds to safely shut down the management controller in the RCU before disconnecting power to the unit.

-===== 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.
