Automation And Remote Led Connector; Connector Pins - HP LTO Ultrium Technical Reference Manual

Automation and remote LED connector

The combined Automation and Remote LED Connector is a 16-pin wafer surface-mount right-angle
connector. 10 pins are used for the ACI/ADI interface and 6 pins for the remote LEDs.

Drive Sense. It is tied low in the drive so that a library can sense the presence of
the drive. The library should have a pull-up resistor on this line.
Low: Drive present
High: Drive not present (3.3 volts)
Library Sense. The drive will not appear on the bus until commanded when low.
The line is pulled up to 5V in the tape drive. The automation controller should pull
this pin low.
Low: Drive is connected to an automation controller
High: Drive is standalone (3.3 volts)
Tape drive reset. The line is pulled up to 3.3V in the drive. The drive will perform
a Drive Reset when this line is pulled low.
The drive sets this pin low to indicate to the automation controller that certain
configured conditions have arisen, such as a SCSI Surrogate CDB.
