DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

Trained on Oracle/STK SL500 tape library.

TASK COMPLEXITY: 2

TIME ESTIMATE: 90 minutes

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW:

No robotics movement in library.

Service required light is on.

Customer has reported the library is not functional or tapes not being moved.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

Library should be offline to the application and the OS.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Refer to: SL500 Diagnostics/Troubleshooting Manual, PN96153

1. Is the library communicating through the operator panel or CLI?
No: The library is likely at fault. Restart the system to establish an operator panel or CLI session.
Yes: Continue...

2. Does the library log have error entries?
No: The site configuration, host, or network is likely at fault. Check the library and host logs for configuration activity. Run site network and connectivity tests.
Note - StreamLine error log entries indicate an unrecoverable fault. This means that the job that the host requested could not be completed, resulting in an error log entry.
Other faults, such as retry operations due to mechanism errors, are logged at a warning severity.
Yes: Continue...

3. Does the library log have error entries associated with the host fault?
No: The site configuration, host, or network is likely at fault.
Yes: The library is at fault.

Determine which library FRU is at fault.Locating the FRU problems in the logs involves:
1. Finding the first error log entry associated with the FRU and the fault.
2. Getting the activity and result information from the log entry.

To determine the current operational state of the FRU using the operator panel or CLI:
- If the current state is "online," then the fault was transient and the FRU is still functioning in the library.
- If the current state is anything else, then the FRU requires operator intervention for fault resolution.

Did a transient mechanism failure occur?
Mechanism failures are recorded in the library log. The mechanism FRU is "online" after a transient failure, but the history of the failure is recorded.
Did a permanent mechanism failure occur?
The mechanism FRU is not "online" after a permanent failure and the mechanism fails further diagnostics or attempts to make the FRU operational.

Likely resolution activities include:
-Run diagnostic tests to verify faults and/or reset the FRU.
- Update firmware (library or tape drive).
- Replace the FRU when directed by service representatives.

Refer to SL500 Modular Library System Replaceable Parts Catalog, PN96120 to replace robot assembly as needed.

Note: 
The Notes, Cautions, and Pictures are NOT shown here.  You must refer to the Manual for all details.  Refer to the Manual for an Original Robot.

Refer to the attached document concerning proper and safe removal of Robotic Module to prevent cable damage. (7-Mar-2014)

Removal of Robot Assembly:
At the rear of the library:
1. Remover power from the library by toggling the power switch to off.
At the front of the library:
2. Use a flat-bladed screwdriver to help disengage the robot facade's ball studs from their receptacles.
3. Remove the facade.
4. Check the park lever to the left of the keypad on the front of the robotics unit.  If the park level is
    positioned to the left, the robot's X table is parked.
   - If the X-Table is parked, go to step 20.
   - If the X-table is not parked, use the following steps to manual park the X-table.
5. Look through the windows in the library doors and check for the position of the X-table.
   - If the table and hand are not visible through the door window, it is likely that the robot is just below the
     parked position.
   - If the X table and hand are visible through one of the door windows, carefully follow the steps for
     manually parking the robotics unit.
6. With your finger, move the robotics park lever to the left and hold it in that position.
7. Use the door key to raise the latch rod and unlock the front door.
8. Continue to hold the park level and open the door.
9. Release the robotics park lever.
10. Use the door key to lower the latch rod.
11. Check the hand to ensure that a customer cartridge is not being held by the gripper.
12. If the hand is facing the left wall and the cartridge is partially extended into a slot or is aligned with a
      slot, go to "step a" and follow those steps.
      If the hand is facing the left wall but the cartridge cannot be extended into a slot because it is not
      vertically aligned with one, go to "step 15" and follow those steps.
      If the hand is facing the rear or right wall, go to "step 13" and follow those steps.
  a. Manually extend the gripper until the cartridge is in the slot and the gripper release screw is accessible.
  b. Turn the gripper release screw clockwise one quarter turn or until the gripper releases the cartridge.
  c. Slide the gripper into the hand.
  d. Go to the note preceding step 16.
13. If the cartridge is extended into a slot, continue with the next step, otherwise go to "step f".
  e. Grip the cartridge or gripper fingers and slide the gripper into the hand until the cartridge is fully
      retracted, or use the belt and pulleys at the rear of the hand to complete this actions.
  f. Slide the hand to the front of the X table.
  g. Grasp the hand and rotate it until it is parallel with the front of the X table and facing the left wall.
14. If the cartridge can be extended into a slot, return to "step a" and follow those steps, if not, read the
      following note and continue with the next steps.

Note: When the cartridge is not vertically aligned with a slot, the X table must be raised to align the
         cartridge with a slot.

15. Use the following steps to vertically align the cartridge with a slot:
  h. Use the X table crank to raise the X table incrementally.
  i. Check the position of the cartridge to the array slots.
  j. Repeat these actions until the cartridge can be extended into a slot.
 k. Go to "step a" and follow those steps.
16. Check the position of the hand.
     If the hand is in its parked position, go to the not preceding step 17.
     If the hand is not in its parked position, follow these steps:
      a. Grasp the hand and move it to the front of the X table.
      b. Rotate the hand until it is parallel with the front of the X table.
      c. Align its mounting screws with the holes on the bottom of the X table.

Note: The X table crank uses a pull-out/push-in repeated action to raise the X table.

17. Use the X table crank in the upper right-hand corner of the robotics unit to raise the X table into the
      robot housing.

Note: You should never put your hand under the robotic tray to push up on it while you are manually cranking the robot to the parked position using the X table crank.  This could result in the Z cables coming off of the Z pulleys and bullwheel."

18. Continue raising the X table until the park level indicates that the X table is parked by moving to the
      left.
19. If you are replacing the RLM card, return to step 15 of that procedure, otherwise continue with the
      next steps.
At the left side of the robotics unit:
20. Reach into the opening and grasp the Z flex retraction handle.
21. Pull the handle out of the opening and away from the front of the robotics unit until the other end of
     the of the handle appears in the opening.
22. Slide the retraction handle back into the opening.
23. Push the latch on the robotics unit door to the right and open the door.
24. Push the locking lever  on the right side of the robotics unit to the left and hold the lever in that position.
25. Use your other hand and insert your fingers into the open door of the robotics unit.
26. Pull the unit until the lever clears the locking hole.
27. Release the lever.
28. Continue to pull the robotics unit out of the library until you can grasp the unit on both sides.
29. With a firm grasp on the robotics unit, slide it out of the base module.
30. Place the unit on a flat surface with the bottom facing up.
31. Press down on the yellow shipping gear lock until it engages the reduction gear.
32. Installing shipping straps on the bottom of the robot by inserting the ends of the straps into the slots
      on the front and back walls of the robotic unit.
33. Follow the procedures for packing and shipping the damaged unit to Oracle.

Replacement of Robot Assembly:
1. Carefully unpack the new robotics unit and set it on a sturdy table or cart with its bottom facing up.
2. Remove the 2 shipping straps and place them with the rest of the packing material.
3. Remove the ESD tape from the containment box.
4. Lift the yellow shipping gear lock to release the gear.
5. Slide the robot most of the way into the base module.
6. Push the lever on the robot door to the right and open the door.
7. Make sure that the guide rail on the left side of the robotics unit is aligned with the slot on the base
    faceplate.
8. Push the unit the rest of the way into the frame.
9. Check that the locking lever on the right is fully seated.
10. If necessary, push the lever to the right.
11. Lift and secure the robotics unit door.
