Replacing a Base or Expansion controller card
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.
• You must power off the library to install or replace this part
or damage can occur.
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 conguration
See “Locating Management functions” on page 63 for instructions on saving conguration 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 Conguration on a library that is in a failed state. Save the conguration 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 137.
