3 Installing the DSPP





This chapter explains how to install a Desktop SunCD Plus Pack (DSPP) to a desktop system in a direct connection, or in a daisy chain with other peripherals.

Before You Start

Before you perform any of the installation procedures, make sure that you have:

An overview of the installation steps is shown in Figure 3-1.

    Figure 3-1 Roadmap for Installing a DSPP with a Desktop System

Verifying the System Environment

Before you begin any tasks involving software, you must first verify your system environment. The SunCD Plus drive can be used in either the
Solaris 1.x or 2.x operating environments.

Once you verify the operating system and its version that you are running, you can refer to the software handbook for this operating system.

Shutting Down the System

Before you can install the DSPP, the system environment must be shut down according to the procedure detailed in your software handbook. There are several steps to shutting down the system. If any one of these steps is omitted, the system may fail to boot or correctly configure the SunCD Plus drive. Some of these steps include:

To shut down the system:

    1. Go to your peripheral handbook for the operating system.
    2. Refer to the section about shutting down the system, then return to this manual after you complete this procedure.

Caution -

The system will not recognize the new device unless you follow the shutdown procedures in the handbook. Specifically, the Solaris 2.x environment uses the new touch /reconfigure command to ensure autoconfiguration when the system is powered on. Be sure to refer to your peripheral handbook for current shutdown and re-configuration procedures.

Powering Off the System

Turn the on/off switch to the off (O) position for each device in the following order:

      a. Peripherals

      Desktop Backup Packs, External Storage Modules, Desktop Storage Packs/Modules, and other external drive units

      b. System unit
      c. Monitor

Warning - Be sure all power switches are turned to the off (O) position. The green light emitting diodes (LEDs) on all units should not be lit and the fans in the power supplies should not be running. The power cord should be plugged into a wall outlet and into the desktop system.

Caution - Always allow 10 seconds between turning off the power and turning it back on again. This pause prevents possible damage to power supply components in the system unit.

Setting the Target Address

Locate the target address switch on the rear panel of the DSPP and set it to the address you chose after performing the Configuring Your System procedure described in the specific software handbook shipped with your drive.

You can set the switch by pressing the button on the top or on the bottom of the switch until the desired address number appears in the window, as shown in Figure 3-2. This figure displays an address of 6 which is recommended as a general purpose value (for CD-ROM drives) to avoid any possible conflicts with other components of a desktop system.

    Figure 3-2 Setting the Target Address Switch

Connecting a DSPP

The following procedures explain how to install a single DSPP in a direct connection to a desktop system, as shown below:

    Figure 3-3 Direct Connection to a System Unit

    1. Position the DSPP as shown in Figure 3-4.

    Allow at least 3 inches (76mm) for ventilation and access to the diskette drive in your system.

    Figure 3-4 Placement of DSPP

    2. Connect the SCSI cable to either SCSI port on the back panel of your system unit.

    To disconnect a SCSI cable or terminator, press in on the clips on the sides of the connector and pull the connector out of the SCSI port.

    3. Connect the other end of this cable to one of the two SCSI ports on the back panel of your DSPP.

    The SCSI port icon, shown in Figure 3-5, is stamped below the ports.

    Figure 3-5 SCSI Port Icon

    4. Install the regulated terminator to the remaining SCSI port on the back panel, as shown below.

    If the DSPP is being installed with other SCSI devices, you must replace any of the older passive terminators with the regulated terminator that was provided.

    5. Connect one end of the power cord to the power receptacle on the DSPP's rear panel (as shown below), and the other end to the power source outlet.

    Figure 3-6 Rear Panel of DSPP

Setting Up a Daisy Chain

If you want to create a daisy chain with one or more DSPPs and other SCSI devices (such as Desktop Backup Packs or Desktop Storage Packs) as shown below, refer to Appendix B, "Small Computer Systems Interface Information." Be sure to use the regulated terminator.

    Figure 3-7 Daisy Chained Connection

Powering On the DSPP

To power on your Sun system unit and DSPP:

    1. Be sure the power switches are off (with the O side of the power switch pushed down) on your Sun system unit and any DSPP connected to it either directly or in a daisy chain.
    2. Be sure each power cord is plugged into an AC power outlet.

Caution - Sun products have been designed to work with single-phase power systems having a grounded neutral conductor. To reduce the risk of electric shock, do not plug Sun products into any other type of power system. Contact your facilities manager or a qualified electrician if you are not sure what type of power is supplied to your building.

    3. Turn the power on (push down on the | side of the power switch) in the following order:
      a. The last device (the one with the terminator attached to it) in the daisy chain
      b. The devices in the middle of the daisy chain
      c. The directly connected device
    4. Turn the power on (push down on the | side of the power switch) to your Sun system unit.
    5. Turn the power on to your monitor.

Note - Failure to turn power on in the sequence described above in Steps 4 and 5 may result in the system unit not recognizing the DSPP.

Configuring the System

System configuration occurs after a system is successfully powered on. If the system shutdown was performed according to the procedure in the software handbook and your system is running Solaris 2.x, your system should automatically configure when you power on the system. In Solaris 1.x systems, you may still need to configure the system.

Follow the procedure below to continue to set up your DSPP:

    1. Go to the peripheral handbook for your operating system.
    2. Refer to the section about setting up CD-ROM drives, then return to this manual after following those procedures.
