To access the serial port, use one of the following:
ssh -t admin@kvm.hcoop.net tip /dev/tts/0 ssh -t admin@kvm.hcoop.net tip /dev/tts/1
One command corresponds to each of the two serial port connectors on the KVM (we're not sure which is which). After executing the command above, your ssh session will give you a console on the chosen serial port (which is probably connected to the remote power-cycling machinery of one of the servers)
