Powering off the library
Verify that all host processes are idle.
Power off the library from the front panel. Depress the power button for 5 seconds and then release
it. If the library is idle, you can release the button when the Ready LED begins flashing. If the library
does not perform a soft shutdown, depress and hold the power button for 10 seconds.
Verify that the robotic assembly is in its parked position. Look inside the base module window to
verify that the robotic assembly is behind the OCP.
Preparing to remove the controller board
1. Unplug the AC power cables from the module containing the failed controller.
2. On the module containing the failed controller, remove the expansion interconnect cables that
connect to other modules, if present.
3. Remove the Ethernet cables and the USB device, if present. (An expansion module will not
have Ethernet or USB ports.)
Removing the base or expansion module controller
