This chapter explains how to remove and replace a tape drive from a Desktop Storage Module.
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:
The mat comes with the new tape drive.
The following figure shows the connector locations for the tape drive.
Figure 6-1 Tape Drive
Figure 6-2 Location of Captive Screws
Remove the cables by pulling on their connector or pull-tab. Do not pull on the cable itself. See Figure 6-1.
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.
See the following figure.
Place the four screws in the container and put the bracket aside.
Figure 6-3 Tape Drive Bracket Assembly
See Figure 6-4.
Figure 6-4 Removing the Handle
Place the screw in the container. Put the handle aside.
Position the tape drive on the other side and repeat step 4.
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:
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.
Position the bracket so that the side with the two captive screws is on the right side of the drive.
See Figure 6-5.
Figure 6-5 Tape Drive Bracket Assembly
See Figure 6-6.
Figure 6-6 Replacing the Handle
Turn the tape drive on the other side. Repeat steps 6 and 7 to install the other handle.
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:
See Figure 6-7.
Make sure to route the power supply cable through the clip located on the power supply. See Figure 6-7.
The surface of the tape drive should be flush with the surface of the front side of 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.
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
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.
