Verifying the power supply installation and operation
1. Verify that the new power supply is operating properly by checking the power supply LEDs:
• The white (1) and green (3) LEDs should be lit.
• The amber (2) LED should be unlit.

2. Using the OCP or RMI, confirm that the power supply is operating correctly; the event that
indicated the power supply was faulty should be cleared.
3. If the UID LEDs are still illuminated, deactivate them using the OCP or RMI.
Replacing a controller board
CAUTION: Parts can be damaged by electrostatic discharge. Keep parts in electrostatic containers
until needed. Ensure you are properly grounded when touching static sensitive components.
CAUTION: You must power off the library to install or replace this part or damage may occur.
IMPORTANT: Do not replace both the base chassis and the base module controller with repair
components in the same procedure. The firmware will not allow the library to operate if both
components are replaced at the same time. The library WWID and serial number are saved in the
controller and within the chassis. When one is replaced, the data from the original component is
transferred to the repair component. If replacing both the base chassis and base module controller,
you must power cycle the library between component replacements.
Identifying the failed component
See the OCP or RMI Home screen to identify the failed component. Activate the UID LEDs from the
Maintenance > UID LED Control screen to locate the library in the data center. For detailed
instructions, see “Identifying a failed component” (page 96).
Saving the configuration
The library configuration settings are on the library chassis and will be restored automatically when
the controller is replaced. However, HP recommends saving the configuration settings before
removing the controller board. See “Saving the library configuration to a file” (page 43) for
instructions on saving configuration settings to a file or USB flash drive via the OCP or RMI.
