Sun N1 System Manager 1.2 Release Notes

Only SSHv1 Is Supported for Serial Console Access (6309107)

The applet used for serial console access from the Web Browser interface uses SSHv1 only for communication back to the N1 System Manager management server. This feature requires enabling SSHv1 for the N1 System Manager management server.

Workaround: If you do not want to enable SSHv1 and the serial console Web Browser interface, you can use the serial console feature from the n1sh command line interface.
