    Figure 4-1 Opening the Top Panel on the SPARCcenter 2000 System (Front View)

4.2 Unpacking and Inspecting the Tape Drive

Caution -

Circuit board components are vulnerable to damage by electrostatic discharge (ESD). An electrostatic charge can build up on the human body and then discharge when you touch a board or a magnetic storage device, such as a tape drive. Such discharge can be produced by walking across a carpet and touching a board, or by any other similar action. Before handling any board or magnetic storage device, make sure you dissipate your body's charge by following these instructions carefully.

Follow these instructions to unpack and inspect the drive:

    1. Unpack the 5.0 Gbyte 8 mm tape drive.
    2. Place the tape drive on top of the bag it was shipped in.

    Placing the drive on the bag will prevent static discharge from accumulating in the device.

    3. Inspect the tape drive for evidence of damage.

    If damaged, keep all contents and packing materials for the carrier's agent to inspect.

    4. Verify that the shipping container has all the contents you will need to install the 5.0 Gbyte 8 mm tape drive.

    The shipping container should have the following items:

    5. Save packing materials for future use.
    6. Determine if there are any jumpers installed on the SCSI ID connector at the rear of the tape drive (see Figure 4-2 for the location of the SCSI ID connector).

    A jumper is a small sleeve that slides over two adjacent pins in the SCSI ID connector to provide an electrical connection. If there are jumpers installed on the SCSI ID connector, remove the jumpers using the needle-nosed pliers.

    Figure 4-2 Location of the SCSI ID Connector and the SCSI ID DIP Switches on the 5.0 Gbyte 8 mm Tape Drive (Rear View)

    7. Set the SCSI ID DIP switches to the down (OFF) positions (see Figure 4-2 for the location of the SCSI ID DIP switches and the proper setting for OFF).
    8. Determine if you will be installing an additional tape drive or replacing an existing tape drive.

4.3 Installing a 5.0 Gbyte 8 mm Tape Drive

Follow these instructions to install a 5.0 Gbyte 8 mm tape drive in your SPARCcenter 2000 system.

    1. Get the mounting brackets for the tape drive from the ship kit.

    If you are replacing the 5.0 Gbyte 8 mm tape drive, you can use the mounting brackets you removed from the old drive.

    2. Use the Phillips screwdriver to secure the mounting brackets to the sides of the tape drive using the four 6-32 pan-head screws that were included with the drive (see Figure 4-3).

    When installing the mounting brackets to the tape drive, make sure the following items are done properly:
