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 

.

individual current state of open 

or closed.
