Replacing the library controller (MSL4048, MSL8048, and MSL8096)
This process applies to the MSL4048, MSL8048, and MSL8096 only. In this process you will:
• Record the library settings.
• Power off the library, unplug the power cord, and remove the Ethernet cable.
• Remove the old library controller.
• Install the new library controller.
• Verify the replacement.
CAUTION: Parts can be damaged by electrostatic discharge. Keep parts in electrostatic containers
until needed. Ensure that you are properly grounded when touching static-sensitive components.
CAUTION: This part is not hot-pluggable. You must power off the library to replace the library
controller.
To replace the library controller:
1. Record the library's settings by writing down the values displayed in the OCP or the RMI.
2. Power off the library from the front panel. Remove the Ethernet cable, if applicable.
3. Loosen the two captive thumbscrews on the library controller and remove it from the library,
as shown in Figure 139 (page 209)).

4. Position the new library controller on the alignment rails and slide it into the library until it is
flush with the back panel, as shown in Figure 140 (page 210). Tighten the two blue thumbscrews
to secure the card to the library.
