Ampere has two models of Servers out: Falcon and Mt. Jades. The Falcons are the older one, and make up many of our utility servers.
I recently had to get in to a serial console on the machine. The IPMI address hosts a web console. From that you can get a serial console on the server, but you need JNLP, which stands for Java Net Launch Protocol. It is implemented by IcedTea in OpenJDK: icedtea-web is the name of the RPM on Fedora 34.
