the ‘sol.sh’ utility, which allows a user to connect to a specific 1S server board’s console port for debugging

In order to reinstall an ONL image, you must change the ONIE bootloader to “Rescue Mode”.
Once the switch is powered on, it should retrieve an IP address on the OpenBMC interface with DHCP. Here we use 10.0.0.131 as an example. OpenBMC uses these default credentials
username: root password: 0penBmc
Login to OpenBMC with SSH:
$ ssh root@10.0.0.131 The authenticity of host '10.0.0.131 (10.0.0.131)' can't be established. ECDSA key fingerprint is SHA256:... Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '10.0.0.131' (ECDSA) to the list of known hosts. root@10.0.0.131's password: root@bmc:~#
Using the Serial-over-LAN Console, enter ONL
root@bmc:~# /usr/local/bin/sol.sh You are in SOL session. Use ctrl-x to quit. ----------------------- root@onl:~#
Note - If sol.sh is unresponsive, please try to restart the mainboard with
root@onl:~# wedge_power.sh reset
