Cartridge Access Ports
The cartridge access ports (CAPs) can be used to add cartridges to the library, or
remove cartridges from the library without interrupting normal robotic operation.
■
The CAP in the Base Module has one five-cell magazine.
■
The CAP in the Drive Expansion Module has two five-cell magazines.
Although the CAPs are not physically connected, they are logically connected. If any of
the CAPs are open, the CAP LED on the keypad will be on, alerting the operator to take
action to close the CAP. If all of the CAPs are closed, the CAP LED will be off.
You can use the keypad on the robotics unit to issue a command for the robot to unlock
the CAP.
The CAP has two settings, ALLOW and PREVENT. ALLOW is the default setting after
you power-on or reset the library. The following table shows how these settings affect
the CAPs. For CAP LED indicator information see “Controls and Indicators” on
page 35 .
