Validate the Component Installation

Verify the CRU or FRU was properly installed and that the library is fully functional.

1. Power on the library (see Power On the Library).
2. Check the OK LED indicators on all CRUs.
3. Verify that the library health state is operational from either the touch screen or the remote interface (see View the Library State).

   If the health state is degraded or failed, see Troubleshoot the Library to assist with resolving the problem.

4. Perform an operational check of replaced CRUs, as applicable:

   • Front Panel — Test the panel for general operation (locate light, touch screen, open the mailslot, and so forth).

   • Module Controller — Confirm that the library recognizes the module controller (Modules area of the touch screen or Library area of the SL150 remote interface).

5. Run the offline self tests from the remote interface (see Run a Self-Test).
6. Set the library to the online state (see Place the Library Online or Offline) and log out of the remote interface.
7. Run host application commands to ensure that the library and drive applications are synchronized. See your host tape application documentation for guidance.
