Mail Slot Access (Left-hand Magazines Only)
Select this option to display the Mail Slot Access screen (Figure 40). This option
provides access to a mail slot while the library remains powered up. Note that a
mail slot is reserved for the first tape cartridge slot in a left-hand magazine, and
can be password protected or fully disabled. If the mail slot is disabled, this menu
button is absent. On four-drive models, solenoids restrict access to the selected
mail slots.
