    Safety Safety The following provides information about topics that are essential to all service and maintenance activity: • Your safety • Preventing electrostatic discharge (ESD) damage to equipment Safety Precautions CAUTION: Potential injury: On-the-job safety is important; therefore, observe the following safety precautions while you are engaging in any maintenance activity.
  • Page 24: Lifting Techniques

    Safety Lifting Techniques Lifting, regardless of how much or how little, can create serious back stress. If you follow these guidelines, you can reduce the risk of back injury: • Do not twist your body to pick up something or to put it down. Twisting puts extreme pressure on your back, especially when you lift or carry objects.
  • Page 25: Electrostatic Discharge Damage Prevention

    Potential damage to equipment: Handle ESD-sensitive components only under ESD-protected conditions. To meet this requirement, always use the Field Service Grounding Kit (PN 4711) and always follow these ESD precautions and procedures when you are servicing StorageTek equipment or handling ESD-sensitive components. ESD Precautions...
  • Page 26: Esd-Protection Procedure

    Safety • Periodically check the electrical resistance of the ground cord and the wrist- strap coil cord. Note: The ground cord should measure less than 1.2 MΩ, and the coil cord should measure between 0.8 and 1.2 MΩ. Repair or replace the cords if they no longer meet these requirements.
  • Page 27: Replace Components

    Safety Replace Components 7. Remove the defective component and place it on the work surface. 8. Remove the replacement component from its ESD-protective package, and install the component in the equipment. 9. Place the defective component in the ESD-protective package. Clean Up 10.
  • Page 28 • Install the equipment from the bottom of the rack to the top of the rack; StorageTek recommends that you place the heaviest items near the bottom of the rack. • Ensure that the equipment in the rack does not create an overcurrent condition, whether equipment is connected directly to the branch circuit or to a power distribution strip.

    Power System Power System The tape library contains one standard AC power distribution unit (PDU) and one standard DC power supply. Notes: • The customer can order an optional AC PDU and an optional DC power supply for redundancy. • The customer can also order an uninterruptible power supply as an optional feature for the library.
  • Page 229: Power Specifications

    For each library, the customer must order the power cable and supply the correct receptacle. Table A-3 on page A-4 lists the StorageTek part number for the cable and plug type as determined by: • Input voltage (first column) • Country (second column) where the library is to be installed •...

  • Page 235: Cooling

    Cooling Cooling Two +43 VDC fans cool the DC power supplies. The fans are in a tray under the electronics module. The fans are monitored by the MPC microprocessor. If a fan fails, a Hall-effect sensor detects the lack of motion in the fan blades, and an FSC is posted to the FSC log.
  • Page 236: Robot

    Robot Robot Figure A-3 shows the robot for the L180 library. The robot is located behind the front door and consists of: • Theta assembly for lateral movement • Z assembly for vertical movement • Hand-camera assembly to mount and dismount cartridges Most of the robot components are mounted on the Z column.
  • Page 237: Theta Assembly

    Robot Theta Assembly The theta assembly is composed of the +43 V theta motor, the PRY card, and the theta drive belt. The theta assembly, under microprocessor control by the MPC card, moves the hand laterally within the library. A closed-loop servo feedback configuration controls theta positioning.

  • Page 239: Initial Program Load Sequence

    Initial Program Load Sequence After the vision system is verified, the hand extension and hand-to-camera calibrations are done. The hand is extended below the calibration block, and the gripper and hand extension are validated. If any hand failure occurs, the MPC card posts an FSC to the operator panel and the FSC log of the library.

Thresholds for the line scan camera are: • Target—readability and accuracy of the image for locating array positions •...
  • Page 241: Drive Targeting

    Initial Program Load Sequence During the audit process: • Cartridges within drives are not audited. • The client software determines how unlabeled, unreadable cartridges are handled. • Whenever an audit is performed, the customer must request a client software update of the audit results. This must be done to maintain identical audit information between the library and client.

  • Page 244: External Interfaces

  • Page 245: Scsi Hvd Or Lvd Considerations

    External Interfaces SCSI HVD or LVD Considerations With the advent of Ultrium tape drives, customers now have choices as to the type of SCSI interface on which they wish to operate: High Voltage Differential (HVD) or Low Voltage Differential (LVD). As shown in Table A-8, the HVD interface allows longer cable lengths, but throughput is lower than LVD;...
  • Page 246: Library Lvd Operation

    External Interfaces Library LVD Operation StorageTek allows the library to be converted to LVD operation through an extra interface card—the MPW card—that attaches to the MPC card. The MPW card fits into Slot 0 on the electronics module bulkhead. The customer orders the MPW card and card cage with library feature code LV02.
  • Page 247: Fibre Channel

    (Other links on the loop act as repeaters.) • Both initiator and target must reside within the same loop. While the library supports this Fibre Channel topology, StorageTek does not recommend it. Its best implementation includes a Fibre Channel hub.
  • Page 248: Hba Requirements

    External Interfaces HBA Requirements CAUTION: Mismatching SCSI operation types: The host bus adapters (HBAs) in the customer’s server must match the library’s SCSI bus type. If the interface to the library is HVD, then the customer’s server must contain an HVD-compatible HBA. Likewise, if the interface to the library is LVD, then the server must contain an LVD-compatible HBA.

  • Page 251: Library-To-Fibre Channel

    Internal Interfaces Library-to-Fibre Channel Library Fibre Channel operation is directed through the MPU card, which is connected to the MPV card. The MPU card slides into the lower slot of the compact peripheral component interconnect (CPCI) assembly, which contains the MPV card. This lower slot is designated Port 0 by the microcode and is the default location that currently must be used.
  • Page 252: Library-To-Cse Port

    Other Interfaces Library-to-CSE Port The CSE port also provides a command line interface to the MPC card, allowing you to clear (purge) the FSC log and run diagnostic tests through a laptop. In addition, you may use this interface to download microcode to the library. This interface is through an RJ45 connection.
