Removal and replacement
This section contains procedures for removing and replacing items that are end-user replaceable. Before
randomly replacing suspect components, see the troubleshooting section to isolate a problem to that
component. Afterwards, see ”Controls and indicators” on page 65 to verify the component is functioning
normally.

Required tools
A #1 Phillips screwdriver is needed for this procedure.
Replacing the library robotics controller
To remove the library robotics controller card:
1. Terminate all library activity and verify that the picker is empty.
2. Power off the library:
a. Open the door at the rear of the rack.
b. Set the library main power switch at the upper right corner to the Off position (see Figure 48 on
page 69).
c. Ensure all power indicators on the power supplies are off.
3. Identify the library robotics controller at the top card cage slot of the base module.
4. Remove all cabling to the library robotics controller while noting cable locations for later reconnection.
5. Use a #1 Phillips screwdriver to loosen the captive screw in the ejector handles at both ends of the
controller.
6. Press the red ejector buttons, and then push the ejector handles outward until the controller disengages
from the card cage. Pull on the ejectors to remove the controller from the card cage.
7. Place the controller into an ESD bag.
To install the replacement library robotics controller:
1. Note the proper orientation of the controller to be installed into the base module card cage slot.
2. Holding the ejectors, slide the replacement controller into the card cage slot. As the controller seats
into the backplane, push the ejector handles inward to fully seat the controller.
3. Tighten the captive screws in both ejector handles.
