Powering on the library
Power on the library by pressing Power on the Base Module just below the Operator Panel. The green
light illuminates. When the library is powered on, it inventories the tape cartridges in the magazines,
checks the rmware version on all modules, and congures the tape drives. Then, the library conrms the
presence of the existing modules, and searches for any new modules.
Verifying the Base or Expansion controller card
1. Verify that the library has the most up-to-date rmware revision. To nd the version of rmware that is
installed on the library, check the Library Properties page of the Management GUI or the Status >
Library page of the Operator Panel.
2. If the Base Module controller is replaced, upgrade the rmware if necessary. Update the rmware
from the Management GUI at Library > Actions > Update Library Firmware.
Important: If you are asked whether to retain the serial number, always select Yes.
3. Check the Attention light on the front panel and login to web interface and check the dashboard for
