Interpreting "Library Not Ready" Messages

The operator panel and Web client user interfaces each include a header that contains the company logo,
the product name, and the three main navigation buttons: Home, Help, and Logout. In addition, a message
in the header alerts you when the library is not ready. (No message displays in the header when the library
is in a ready state.)
On the operator panel, LIBRARY NOT READY flashes at regular intervals whenever the library robotics are
not yet ready to perform library functions. To view more information about the library's condition, select
Tools > About Library. The State field on the About Library screen will display Not ready, followed, when
applicable, by a brief explanation. For example, if the library door is open, the State field will display: Not
ready, door is open.
The header in the Web client user interface also alerts you when the library is not ready. For instance, if the
library door is open, the header will display the following message: Library's door is open.
"Library not ready" messages appear in the header in the operator panel and the Web client user interfaces
under the following circumstances:
• The robot is in the process of calibrating. When the robot has finished calibrating, the "library not
ready" message will no longer appear.
• The robot cannot calibrate. For example, a fiducial label is missing, preventing the robot from
calibrating.
• The robot requires manual intervention. For example, the picker contains a tape cartridge that it
cannot unload.
• The library door is open. The robot will not operate if the door is open.
• If none of the above situations apply, but the library is still not ready to operate, the header will
display a "library not ready" message without additional detail. The library generates a RAS ticket
whenever the library enters a "not ready" state. The RAS ticket may provide information that can
help you troubleshoot the problem. See
information.
"Library not ready" messages continue to display in the header, as well as on the About Library screen until
the issue has been resolved, and the robot has completed its calibration.
You may not see the "library not ready" message in the Web client user
Note
interface until the browser refreshes. Similarly, even if the problem has been
resolved, the "library not ready" message will not disappear from the Web client
user interface until the browser refreshes.
