Q: I can’t find enb.log.
A: Usually, you can find enb.log by following: https://handbook.rapid.space/rapidspace-How.To.Monitor.Your.BBU.On.Panel#Access_BBU_Logs. If enb.log is missing, the eNB/gNB probably didn’t start. Check enb-info.log for confirmation.
Here is an example in the enb-info.log:
/srv/slapgrid/slappart0/etc/enb.cfg:45: field 'n_id_cell': range is [0:503] (LTE Cell #0)

The example above means n_id_cell is out of range.
In your cell instance tree, verify LTE cell parameters and Apply
Once it starts cleanly, enb.log will appear in the same log directory.
