During the install process, the user is prompted to provide the username of the user that will own the Spectrum installation. This will also be the default user. The password for this user will be "spectrum".
If you do not remember the username of the user that owns the Spectrum installation, you can find it in two places on the SpectroSERVER system:
1. The OWNER parameter in the $SPECROOT/.installrc file
2. The initial_user_model_name parameter in the $SPECROOT/SS/.vnmrc file
