4. With the Operator Panel or the Management GUI, check for any events. The event that indicated that
the controller was faulty is cleared.
5. If the base module controller is replaced, the library configuration is automatically restored. Validate
the library configuration, and complete a Restore if the library configuration was not restored.
6. If the UID LEDs are still illuminated, deactivate them by using the Operator Panel or Management GUI.
7. Resume the host applications.
Installing, removing, or replacing an accessor and spooling
mechanism
Powering off the library
Verify that all host processes are idle, then power off the library from the front panel. Depress Power and
hold it for 5 seconds. If the library does not complete a soft shutdown, depress and hold Power for 10
seconds.
Important: Under normal circumstances, when the library is powered off by using the front Power, the
robot automatically parks and locks into the Base Module behind the Operator Panel. If you are given a
choice during the power down procedure, choose the default park position. To protect the spooling cable
or other sensitive parts, the accessor must be in the Base Module before any components are removed
from the library. If it is not, follow the procedure for returning the accessor to the base module. See
"Returning the accessor to the Base Module" on page 172.
Preparing to remove the accessor and spooling mechanism from the Base Module
1. Loosen the front captive screws that connect the Base Module to the rack two full turns.
2. If adjacent Expansion Modules exist
a. Loosen the front captive screws two full turns on the adjacent expansion modules.
b. Unlock the alignment lever.
c. Disconnect and completely remove the expansion interconnect cables from the Base Module and
from the adjacent modules. Removing the expansion interconnect cables completely prevents
damaging the cables when the module is moved in and out of the rack.
3. Disconnect the power supply cables on the Base Module.
4. Disconnect the Ethernet, SAS, and Fibre Channel cables from the Base Module.

CAUTION: Parts can be damaged by electrostatic discharge.
Keep parts in electrostatic containers until needed. Ensure
that you are properly grounded when static sensitive
components are touched.
Warning:
When a module is extended from the library - to reduce the
risk of personal injury or damage to equipment
• Extend the rack-leveling jacks to the floor.
• Ensure that the full weight of the rack rests on the leveling
jacks.
• Verify that the rack is level side to side and front to back.
• Install the rack stabilizer kit on the rack.
• Extend only one rack component at a time. Racks can
become unstable if more than one component is extended.
