Connecting a Serial Cable for Tape Libraries
The Internal LTO-1 FC drive includes an RS-422 serial interface for tape libraries. This connector is
located on the lower left side of the back of the drive (see Figure 12 on page 26).
Table 5 on page 26 shows the pin descriptions for the serial interface connector. The pins on this
connector are set on 2-millimeter centers. The drive uses pin 1 to detect the presence of a tape
library. The serial interface cable must connect this pin to the adjacent pin 3.
