The MBL just needs to be connected to your network router/switch via CAT5. It sounds to me like you may not have SSH turned on in the dashboard.
To enable SSH load your MBL dashboard and add /ssh after the /UI at the end of the web address up top.
Example:
http://192.168.1.51/UI/ssh
From there tick the SSH Access box to enable SSH. Note the username and password on the same page and use those in putty when requested.
User Name: root
Password: welc0me
That’s a zero and not a capital o in welc0me
Good luck
