Important: Do not replace both the base chassis and the Base Module controller card with repair
components in the same procedure. The rmware does not allow the library to operate if both
components are replaced at the same time. Critical library information is saved in the controller card
and within the chassis. When one is replaced, the data from the original component is transferred to the
repair component. If both the base chassis and Base Module controller are replaced, you must power
cycle the library between component replacements.
Saving the conguration
See “Locating Management functions” on page 79 for instructions on saving conguration settings to a
le with the Management GUI or with the Operator Panel. This procedure is done when a Base Module
controller card is replaced, or as an extra precaution when both the controller card and the module are
replaced.
Note: Do not do a Save Conguration on a library that is in a failed state. Save the conguration on a
working library only.
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 modules or drives 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.
