of the base chassis used to enter tapes into the library and to remove tapes from the
library. Previous StorageTek libraries called this a CAP (Cartridge Access Port).

the Standard Mailslot) when the library has the expanded mailslot configuration. The
mailslot capacity expands from four cartridges (Standard Mailslot) to 19 cartridges.
management information base (MIB)

strings into readable text that identifies each data object within the message.

by a cable.
