I/O stations are on the right side of the front panel of the library to enable the inserting and removing of cartridges without interrupting normal library operations. An expansion module’s I/O station has a capacity of up to five cartridges, depending on where it is located. If it is the lowest module in the rack for the library, it has only four I/O slots available. 

Individual I/O station elements cannot be shared between logical libraries. Importing or exporting cartridges in a logical library without an assigned I/O station requires magazine access, which takes the whole library offline. 

When an operator places cartridges in the I/O station and closes it, the library scans the slots to update the library inventory. Cartridges should then be moved to storage slot locations by using the Web User Interface (Web UI) or your backup application. Using the Web UI, cartridges can be moved from one logical library’s  I/O station slot to a storage slot in another logical library. However, a warning alert box is shown and the action must be confirmed. 

To unlock the I/O station, click Library →  Modules and Magazines →  Actions →  Unlock I/O Station  from the management interface. The station can then be opened by pulling on the magazine access handle. The magazine I/O button LED will indicate status of the I/O and magazine, as shown in Table 12-2.
