I'm shooting in the dark here because I've never seen a Dell 136T library,
but some tape libraries have an option to use the mailbox slots as regular
slots, disabling the mailbox feature entirely.

Specifically, the StorageTek L-20 has a physical latch that holds the
mailbox (also called a "CAP", Catridge Access Port) closed, coupled with a
menu selection to use the (single) CAP port as a regular slot. You might
want to check if the 136T has something similar.
