This chapter explains how to remove a disk drive and how to install a 1.05 Gbyte hard disk drive in the SPARCstation 10 system.
Before you begin:
The information in this chapter is presented in the following order:
Note - See Appendix B for descriptions of SCSI ports, types of connections, SCSI termination, and cable length.
Refer to the next page for a graphical representation on how to remove the cover; to attach a wrist strap; and to replace the cover. The figure is supported by the procedures presented on the next several pages.
If you are installing the drive into a new system, plug the power cord into the back of the system and into a grounded AC outlet. But do not turn the system on.
The screw will remain attached to the back panel after it is fully loosened from the cover.
Push the cover forward until its hinge tabs are free of the system unit.
The wrist strap provides grounding between your body and the chassis for static electricity.
Caution -
When you are finished working within the SPARCstation 10 system:
If the drive is not fully forward in the mounts, the top cover will not close.
Figure 3-1 Opening and Closing the SPARCstation 10 System
You should hear a loud click if the cover is closed correctly when the plastic retainer clip snaps the cover to the back panel.
Be sure not to overtighten.
Refer to the next page for a graphical representation on how to remove a drive and how to remove the drive bracket. The figure is supported by the procedures presented on this page.
The procedure for replacing a drive requires that you remove the grommets and bracket from the previously installed drive in order to install them on the replacement drive since they are not shipped with the replacement drive. Grommets are circular, plastic eyelets through which a screw or peg can be passed through to seat a drive into the drive mounts.
Caution - Do not disconnect the external power cord from the system unit or from the wall power outlet. This connection provides the ground path necessary to safely remove and install a disk drive.
As an additional aid, you can order the SPARCstation 10 Field Service Manual which describes how to repair system problems by running diagnostic programs, and how to remove and replace parts, such as hard disk drives.
See Chapter 1, "Before You Start."
Drive position 1 is located in the corner of the chassis. Drive position 0 is located between the diskette drive and Drive position 1.
Figure 3-2 Removing a Disk Drive
This section describes the procedures to install a 1.05 Gbyte disk drive into the SPARCstation 10 chassis. If you are installing only one disk drive, place that drive in Drive position 1 (in the corner).
You can order the following types of drive kits:
If you ordered a complete drive kit, the shipping box should contain the following components:
The first step for an installation is to unpack the disk drive from the shipping box. Compare the packing list with the hardware you received. Place the drive on an antistatic surface, such as the antistatic bag the drive was shipped in, with the PCB side up. Save the box and the packing material in case you have to ship the drive at some future date.
The drive you have received is a standard connector, 1.05 Gbyte SCSI disk drive. It is approximately 1 inch high and 3.5 inches wide. It supports fast SCSI at 10 Mbytes per second. Turn to the next page to view graphical representations of the Conner and of the Seagate 1.05 Gbyte drives and compare them with your drive to determine which vendor manufactured it.
While all performance specifications are exactly the same for both drives, the jumper locations and settings are different for each drive. Once you have identified which drive you have, only follow the instructions for that specific drive.
Once you have determined which drive you have, you should inspect it to locate the jumpers and to verify their settings.
If you ordered just a replacement drive, the shipping box should only contain one of the two 1.05 Gbyte low profile disk drives shown below:
Figure 3-3 The Seagate 1.05 Gbyte Disk Drive
Figure 3-4 The Conner 1.05 Gbyte Disk Drive
Perform the following procedures to unpack and inspect the drive. Turn to the next page for a graphical representation on how to inspect a drive. The figure is supported by the procedures listed on this page.
Note - Have the wrist strap attached and the external power cord connected to the subsystem and to the power outlet when you handle the drive to verify the jumper settings. Do not have the subsystem powered up when you do this.
See Figure 3-5 for the Seagate drive and Figure 3-7 for the Conner drive. These figures represent how the jumpers should be set when you receive your drive.
For the Seagate drive, see Table 3-1 for a description of each jumper, and Table 3-2 for the target address settings.
For the Conner drive, see Table 3-3 for a description of each jumper, and Table 3-4 for the target address settings.
See Figure 3-2 to identify the drive positions.
If the settings are the same, leave them as they are. If the settings are not the same, change them to match the settings in the figure. Use needlenose pliers to install or remove jumpers.
If the settings are the same, leave them as they are. If the settings are not the same, change them to match the settings in the figure. Use needlenose pliers to install or remove jumpers.

The 1.05 Gbyte hard disk drive is a Small Computer Systems Interface (SCSI) device. Each SCSI device in your system needs a specific and unique SCSI ID. Refer to the handbook that is appropriate for your operating system to determine which SCSI addresses are available to you.
Perform the following procedure to determine the number of internal disk drives in your computer system and their SCSI addresses:
See your handbook for SMCC peripherals if you need help.
You should now see the ok prompt.
A list of the devices attached to the SCSI bus of the host should be displayed.
If you need references to help with the commands listed, see the handbook that came with your peripheral.
Refer to the table below for the SCSI target address settings for a drive in either Drive position 0 or Drive position 1. These settings are only recommendations and you must change them according to your specific configuration.
Note - Do not duplicate SCSI target address settings on the same SCSI bus.

Refer to Figure 3-9 for a graphical representation on how to install a drive.
The SPARCstation 10 system can accommodate two disk drives (use Drive position 1 if you are installing only one drive). Each 1.05 Gbyte disk drive is secured to the chassis with a bracket and mounting grommets. Grommets are circular, plastic eyelets through which a screw or peg can be passed through. An internal disk cable and a power cable (already installed in the SPARCstation 10 system) connect to each drive.
See Figure 3-2 to identify the drive positions.
Place the drive on an antistatic surface.
Two of the screws are for the sides, and four are for the base.
Figure 3-9 Installing a Disk Drive
Make sure that the power cable is long enough to reach the back of the chassis. If it isn't, try to get more slack by working out more of the cable out from the clips in the base of the chassis.
See Figure 3-9. If the drive isn't seated properly, the cover will not close correctly.
System configuration occurs after a system is successfully powered on. If the system shutdown was performed according to the procedure in the software handbook, your system should automatically configure when you power on the system.
To complete the installation of the 1.05 Gbyte low profile disk drive into your SPARCstation 10:
