Blueprints with 7.2 Split and Benetel RU
These blueprints run an OAI gNB over the O-RAN 7.2 fronthaul split with a Benetel RU, and the Open5GS 5GC.
Check the RU
Before installing a blueprint, confirm that the RU discovery service reports the Benetel RU with brc extract infra. You should observe output like the following:
user@ctrl:~$ brc extract infra

tip
If you don't see any RU listed under DEVICES, refer to the troubleshooting guide.
In this example the Benetel RU is detected on two worker nodes. Athena assigns a discovered RU to each access section, so the blueprints do not name the node.
Deploy a blueprint from the control-plane node with brc install network <file>.yaml.
It should finish without errors and print the Kubernetes resources it created.
Follow the deployment with brc observe and wait until every Element other than the UE is in the 1/1 Y state.
warning
These blueprints contain only the Network. Add a UE with the UE blueprints,
using the preferred-access and target-cores given in the last line of each file.
