How to Remove / Replace Hand Assembly (Picker ASM) in C4 Library.

Solution

DISPATCH INSTRUCTIONS
- WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED:
Knowledge of the C4 library and OEM tape drives.

- TIME ESTIMATE: 60 minutes

- TASK COMPLEXITY: 2

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
- PROBLEM OVERVIEW:
The hand picker assembly is not functional and requires replacement.

- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?:
All work should be stopped on the C4 unit and tape drives.  The C4 and tape drives should be taken offline to the software application and operating system.  The unit needs to be powered off.

- WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:
Refer to the C4 Service Manual for complete instructions on how to remove/replace the hand picker assembly.

Extreme caution must be taken as the cable and other parts are easily broken.

Part Numbers:

• F380-1506 [F] C4 Hand Assembly, RoHS:Y
• Next higher Assembly if cable should be damaged -  F380-1503 [F] C4 0 Drive Chassis, RoHS:YL
• F380-1558 [F], Hand Umbilical Cable

To remove the library robotic assembly:
1. Using the OCP, open the front doors and remove all tape cartridge magazines (see Library Operations
   on  page 52).
2. Turn off the library (see Turning Off the Library on page 45.
3. From the back of the library, disconnect all power, Ethernet, and SCSI cables from the library and note
   their locations for later reinstallation.
4. To remove the library chassis from the rack:
   a. Loosen the captive screw securing the power supplies to the chassis and remove the power supplies
       from the back of the library (see Replacing a Power Supply Module on page 144).
    b. Loosen the captive screws securing the tape drives to the chassis and remove the tape drive(s) from
        the back of the library (see Replacing the Tape Drive on page 172).
    c. Remove the PHILLIPS screws securing each side of the chassis to the rack mounting rails and remove
       two Allen screws securing both clamps on the back of the library.
    d. Remove the library from the rack and place the library on a table approximately waist high.
5. Remove the ten PHILLIPS screws securing the top cover to the library chassis (see figure 99).
6. To raise the robotic assembly platform using the platform crank. (see figure 100):
    a. Remove the front bezel (see Door Assemblies on page 179 for more information).
    b. Locate the belt post in the upper left-hand corner of the library chassis and place the platform crank
       on the post.
    c. Turn the platform crank until the robotic assembly platform is at the topmost position in the library.
7. Remove two #10 Torx screws from each of the corner track pieces and remove the track pieces from
    the library. The left-hand corner track piece has a cable attached. (see figure 101).
8. Remove the metal spring securing the ribbon cable (see figure 102).
9. Move the robotic assembly towards the open portion of the robotic track and lift the assembly up and
    out of the library (see figure 103).
10. Disconnect the ribbon cable located on the base of the robotic hand assembly and remove the cable
      restraint with a #10 Torx screwdriver.
11. Lay the robotic hand on the top of the library so the cable connector is exposed (see figure 104).
12. Reconnect the ribbon cable to the base of the robotics hand assembly and slide the ribbon cable into
      the cable alignment tool to ensure the cable height is correct (see figure 104).
13. Install the replacement robotic hand assembly into the library ensuring that the belt post lines up and
      inserts into the base of the robotic assembly (see figure 103).
14. Move the robotic assembly towards the front of the library and loosely install the two corner track
      pieces with four #10 Torx screws each (see figure 101).
15. Place the spacer block over the corner track pieces to ensure the correct track spacing (see figure
     106).
16. Tighten the four #10 Torx screws securing the corner track pieces to the robotics platform and remove
      the spacer block.
17. Install the spring into the library as shown in figure 102.
18. Install the top cover on the library chassis and secure with ten PHILLIPS screws (see figure 99).

The robotic hand assembly replacement is complete.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
The C4 and tape drives need to be powered back on.  Diagnostic tests need to be done to verify the operation of the C4.  Once this is complete, bring the C4 and tape drives online to operating system and software application.
