I have a RAK 4240 (which is the main board of the RAK 7249), set up on 8-channels and on freq AU915. It is installed and working. I have a second RAK 2247 which I inserted into the vacant, what-would-be, concentrator-1 PCIe slot. The power LED lights up. However, the gateway setup screen does not see the new concentrator-1. I have swapped 2247s but still only get concentrator-0. I removed concentrator-0’s 2247. TTN sees the gateway, but no traffic flows. The 2247 in concentrator-1 slot power LED comes on, but the Rx LED does not light at all. I am using firmware version 1.1.0062_Release_r202 which I have re-installed.
I have had great help from Vladislav, but were baffled.
Can anyone shed light on the problem, please. Thank you
