NOTE: “Step 3: Removing the failed robot” and “Step 4: Installing the new robot” of this procedure should, together, be performed in less than 10 minutes. When you reach Step 3, the library's local User Interface (UI) provides a robot replacement wizard that includes a timer that counts down from 10 minutes. After 10 minutes, the library goes to a Not Ready state and any in-progress backup or restore jobs may fail.
1. Remove the new robot from its packaging by using the yellow handle and lift area (indicated in Figure 1). Place the robot horizontally on a clean flat surface, such as a table or the floor. The yellow handle must face up. CAUTION: While lifting and moving the robot, only use the handle and the lift area shown in Figure 1. Lifting from other locations might damage the robot. CAUTION: Do not stand the robot vertically on its base unless you are holding it securely with two hands.

Loosen thumbscrews to open door. 3. Referring to Figure 3, set the power rail collectors to the correct position (right-side robot or left-side robot) by sliding the thumbscrews up or down as described in this step. NOTE: The collectors may already be in the proper position.
c. Slide the thumbscrews and bracket all the way up or all the way down until the hole in the bracket fits over the other pin in the collector door. The thumbscrews and bracket all move together: • If this is the left-side robot or a single robot library, slide the thumbscrews and bracket all the way toward the bottom of the robot. • If this is the right-side robot, slide the thumbscrews and bracket all the way toward the top of the robot. Figure 3 Setting the power rail collectors 1.
5. Referring to Figure 4, remove the robot shipping restraint: a. Unscrew two captive thumbscrews on the front of the picker that secure the restraint. b. Tilt the top of the restraint toward you slightly to disengage two pins in the bottom of the restraint from two holes on the back side of the picker, then lift out the restraint. Sometimes the pins are tight, and it may be easier to push the restraint down and through to the rear of the robot and remove the restraint from the rear. c.
6. Referring to Figure 5, set the X-preload tensioner by pushing the retaining pin up into a hole on the drive gear: a. Using two hands, use one thumb to rotate the gear that sits on top of the spring toward the back of the robot, while at the same time using the other hand to pull the drive shaft toward the front of the robot until a hole becomes available in the bottom of the gear into which to push the pin. b. Push the pin upward so that it slides into the hole.
7. Referring to Figure 6, engage the robot kickstand: a. Lift the picker by the yellow handle just above the kickstand engagement tab. b. Pull the locking lever back, then lower the picker slightly until the lever engages, and the picker is held in place by the kickstand. c. Let go of the picker handle. Figure 6 Engaging the kickstand 1. Raise handle to lift picker into position 2. Locking lever 8. For now, leave the robot lying on its side close to the module containing the failed robot.
5. Select Robot Access and click Next. The Robot Access Wizardscreen appears. 6. Click Next. The Robot Selection screen appears.
7. Select the check box for the robot you want to replace (left or right in dual robot systems) and click Next. The Robot Replacement Preparation screen appears. The parking module belonging to the robot to be replaced flashes.
8. Click Prepare. The library finishes the current command and begins to report Becoming Ready status to hosts. If this happens, a dialog box appears on the screen, stating that it is safe to open the door, and the 10-minute timer starts counting down. 9. Wait for the Attention! dialog box to appear, letting you know that it is safe to open the door. 10. Click OK to close the dialog box. (The dialog box closes on its own after 15 seconds.
11. The Replace Robot Status screen appears, showing the timer counting down. Step 3: Removing the failed robot To remove the failed robot: 1. Open the library access door corresponding to the failed robot. 2. Referring to Figure 7, move the robot’s yellow locking lever into the full unlocked position. You need to pull down on the handle to disengage the lever, then move it all the way to the left. Make sure it snaps into place after you move it. 3.

Lift the picker by the yellow handle just above the kickstand engagement tab. b. Pull the locking lever back, then lower the picker slightly until the lever engages, and the picker is held in place by the kickstand. c. Let go of the picker handle. 5. Open the power rail collector door by loosening two thumbscrews; see Figure 8.
Figure 8 Closing and opening the collector door 1. Tighten these thumbscrews to close door. Loosen thumbscrews to open door. 6. Place your hands in the proper positions on the robot so that when you remove the robot, you will not hit your hands on library components. (One hand holds the yellow handle, the other holds the vertical rail in the lift area shown in Figure 1.) 7. Slide the robot toward the center of the library until it is no longer underneath the loader bracket.
Step 4: Installing the new robot To install the new robot: 1. Lift the new robot carefully off of the floor. 2. Referring to Figure 5, check the pin position in the X-preload tensioner to be sure the pin is still in the hole and has not disengaged. If the pin has dropped out, return to Step 6 under “Step 1: Unpacking and preparing the new robot” (page 3). 3. Engage the robot kickstand (see Figure 6): a. Lift the picker by the yellow handle just above the kickstand engagement tab. b.

Hold the robot at the lift points in the middle of the vertical rails, and push it firmly toward the back of the library until it hits the full back position shown in Figure 9 and the mushroom button hits the bottom. Hold the robot at the lift points in the middle of the vertical rails.
10. Referring to Figure 11, verify that the gears are engaged: a. The top gear on the robot should engage the teeth of the top X-axis gear rack. b. The two rubber rollers on each gear rack should straddle the non-notched rack that is closer to the back of the library. c. The larger gear wheel on the middle rail should be forward of the gear rack. If the gears are not engaged, remove the robot and start over at Step 2.

Referring to Figure 13, verify the robot is vertical by making sure that the robot vertical rails line up with the white scribe lines on the top, middle, and bottom load position gear racks. You may need to move the robot left slightly so the scribe lines are to the right side of the robot.
Figure 13 Verifying the robot is vertical by checking scribe lines 1. Scribe line locations in right-most module (for dual robot libraries) 2. Yellow scribe line locations in control module or left-most module 13. Slide the robot 25 to 50 mm (1 in to 2 in) to the left until the collectors are positioned in front of the power rail load guides.

This pushes the collectors into the power rails. 15. Referring to Figure 14 through Figure 16, verify that the collectors are in their correct position in the power rails: 22 • On both left- and right-side robots, the bottom collector is always in the bottom position (position 7).

Verify robot motion: Push or pull on the robot handle to move the robot toward the center of the library, just far enough so that it passes over the first junction in the gear racks. If it slides smoothly without resistance, noise, or jerkiness, everything is properly installed. Proceed to the next step.
If you cannot determine the problem, remove the robot from the library, and start over at Step 2. (To remove the robot, first move it so that it is not directly underneath the loader bracket. Open the collector door, unlatch the yellow plastic locking lever, lift the robot up so that its rollers clear the racks, and pull it out of the library, top end first.) 17. Referring to Figure 5, disengage the robot kickstand by lifting up on the yellow lever to release the locking tab.
