Login Overview - HP 12500 Configuration Manual

Login overview

The first time you access the device, you can only log in to the CLI of the default MDC through the
console port. After login, you can create non-default MDCs, change console login parameters, or
configure other login methods including console login, AUX login, Telnet login, SSH login, and SNMP
access.
Non-default MDCs have no console or AUX port. To log in to a non-default MDC for the first time, you
must log in to the default MDC and then switch to the non-default MDC using the switchto mdc command.
After you log in to a non-default MDC, you can configure Telnet login, SSH login, or SNMP access.
Then, administrators of the default MDC and those of the non-default MDC can access the non-default
MDC through Telnet, SSH, or SNMP.
