6 Tape Drive





This chapter explains how to remove and replace a tape drive from a Desktop Storage Module.

Removing a Tape Drive Assembly

Follow Chapter 4 to select tools, halt the system, disconnect the Desktop Storage Module , remove the cover of the module and attach the wrist strap.

Caution -

The tape drive contains electronic components that are extremely sensitive to static electricity. Ordinary amounts of static from your clothes or work environment can destroy the components.

Do not touch the components themselves or any metal parts. Wear a grounding strap when handling the drive. See "Attaching a Wrist Strap" in Chapter 4.

Do not disconnect the power cord from the power outlet of the system unit or from the wall outlet. This connection provides the ground path necessary to safely remove and install the hard disk drive.

Make sure that the power of the system unit is turned off by checking that the green light-emitting diode (LED) at the front of the chassis is not lit and that the fan is not running.

To remove a tape drive, do the following:

    1. Place an anti-static mat shiny side up, next to the DSM.

    The mat comes with the new tape drive.

    2. Disconnect the SCSI cable (by spreading the ejector tabs) and the select switch cable from the tape drive.

    The following figure shows the connector locations for the tape drive.

    Figure 6-1 Tape Drive

    3. Turn the captive screws on the bracket at the side of the drive counterclockwise to loosen the screws.

    Figure 6-2 Location of Captive Screws

    4. Slide the tape drive towards the rear of the chassis.
    5. Lift the tape drive assembly up on the power supply side and lift it away from the Desktop Storage Module.
    6. Disconnect the power cable from the tape drive.

    Remove the cables by pulling on their connector or pull-tab. Do not pull on the cable itself. See Figure 6-1.

    7. Place the tape drive assembly on the anti-static mat.

What's Next

    You have removed the tape drive assembly from the DSM. If you removed the tape drive assembly to get access to the defective power supply or I/O bracket assembly, see "Removing a Power Supply" in Chapter 7, or "Removing an I/O Bracket Assembly" in Chapter 8. See the following section if you removed the tape drive assembly because it is defective.

Removing the Bracket and the Handles From the Tape Drive

    1. Turn the tape drive assembly upside down on top of the antistatic mat.

    See the following figure.

    2. Remove the four screws that secure the tape drive to the bracket.

    Place the four screws in the container and put the bracket aside.

    Figure 6-3 Tape Drive Bracket Assembly

    3. Position the tape drive on its side.

    See Figure 6-4.

    Figure 6-4 Removing the Handle

    4. Remove the screw that secures the handle to the tape drive.

    Place the screw in the container. Put the handle aside.

    5. Remove the other handle.

    Position the tape drive on the other side and repeat step 4.

Preparing a Replacement Tape Drive

Make sure that the wrist strap is still attached to your wrist and the metal casing of the power supply. The power cord should still be connected to both the power outlet of the DSM and to the wall outlet.

To prepare a replacement tape drive:

    1. Gently turn the new tape drive upside down.

    Position the drive so that the connectors are facing away from you. The SCSI connector should be at the lower side of the tape drive.

    2. Place the tape drive bracket on the bottom of the tape drive.

    Position the bracket so that the side with the two captive screws is on the right side of the drive.

    3. Align the four screw holes on the bottom of the tape drive with the four screw holes on the tape drive bracket.

    See Figure 6-5.

    Figure 6-5 Tape Drive Bracket Assembly

    4. Take the four screws from the container and secure the tape drive bracket to the tape drive using these screws.
    5. Turn the tape drive on one of its sides.
    6. Place the handle on the side of the tape drive and align it so the tab of the handle is in the slot provided in the bracket.

    See Figure 6-6.

    7. Secure the handle to the tape drive by installing the screw.
    8. Install another handle to the other side of the tape drive.

    Turn the tape drive on the other side. Repeat steps 6 and 7 to install the other handle.

Replacing a Tape Drive Assembly

Attach the wrist strap to your wrist and to the metal casing of the power supply. Make sure that the power cord is connected to the power outlet and to the wall outlet.

Caution -

Do not disconnect the power cord from the power outlet of the system unit or from the wall outlet. This connection provides the ground path necessary to safely remove and install the hard disk drive.

Make sure that the power of the system unit is turned off by checking that the green light-emitting diode (LED) at the front of the chassis is not lit and that the fan is not running.

Follow these steps to replace a tape drive assembly into the DSM:

    1. Position the tape drive assembly so that the connectors are pointing to the rear of the Desktop Storage Module.

    See Figure 6-7.

    2. Connect the connector from the power supply cable to the tape drive (P1).

    Make sure to route the power supply cable through the clip located on the power supply. See Figure 6-7.

    3. Lower the drive assembly into the Desktop Storage Module, positioning the drive as close to the power supply and the fan as possible.
    4. Lower the drive assembly completely. Rock it back and forth to make sure the drive assembly sit properly.
    5. Slide the tape drive toward the front side of the chassis.

    The surface of the tape drive should be flush with the surface of the front side of the chassis.

    6. Tighten the captive screws on the tape drive bracket clockwise until the bracket is secured to the chassis.

    You may have to shift the drive assembly back and forth until the screw holes are aligned with the captive screws. See Figure 6-7. Do not use a power screwdriver on a captive screw.

    7. Connect the select switch cable to the tape drive.

    Make sure to orient the connector with the arrow facing up as shown in Figure 6-7. This connector is not keyed.

    Figure 6-7 Tape Drive

    8. Connect the SCSI cable to the tape drive.

    Make sure that the EMI ferrite on the SCSI cable is pushed as close as possible to the I/O bracket. Push the ejector tabs close to the connector. Then, twist the cable half turn (180 degrees) before connecting the connector to the drive. These connectors are keyed, so they can be connected only one way.

    9. Follow Chapter 10 to detach the wrist strap, replace the cover, connect the Desktop Storage Module, and power up the system.
