Backup Exec Library Expansion Option

HI,

I am having a LT05 tape which is currently connected to my backup exec 2012. I am plaining to purchase Dell 8 slot Tape library. 

To my understanding that When you install Backup Exec, it just support for the first drive only which is my current LT05, therefore to make backup exec 2012 talk with Dell tape library, i have to purchase Backup Exec Library Expansion Option.

Do i understand correctly ?

Thank you very much for you help.

Regards,
