A question about Cisco Boson simulator passwords

Dear All: I desgned a network using Boson simulator. While trying to login to a 5000 series switch, I suddenly had a question of password. Tried cisco and password but both failed. Do any one know the default password of such a series of switches.
Thanks and Regards.

Dear My Friend,
I want to Tell You something that the Boson Simulation Don't Have any Default Passwords As iKnow , Because the Devices Have no Passwords in its Default State.
Regards
