.
NOTE:
Tape drives that are installed in rack 1 of a control module or an expansion module replace storage
in columns 1 and 2. Because drives are installed from the bottom to the top, you lose the storage
starting in section 10 first. You do not lose the magazine in columns 1 and 2 of section 5.
Column 1 never contains storage in the control module.
Figure 16 shows the section, column, and row numbering for rack 2 of a library that contains LTO
cartridges. This is shown as you face the inside of the opened module door.
NOTE:
The cartridges in the 24-slot LTO I/E station are addressed as part of column 3 and are in sections
1 through 4 (top to bottom). When you have an I/E station installed on rack 2, there are no cartridges
in columns 3 and 4 of section 5. See
Figure 16 .
