This chapter explains how to install and remove the 1.05 Gbyte hard disk drive in the SPARCstation IPC system.
Caution -
Before you begin:
Recently released Sun systems and peripherals are now supplied with new regulated (active) SCSI terminators. Previously, Sun supplied standard SCSI terminators. Both types are shown below.
All SCSI systems must be terminated at the first and last units attached to the SCSI bus. A terminator is built in to all SBus SCSI cards and to all host systems. For the last unit attached to the SCSI bus, the new regulated terminators provide the improved impedance matching required for fast SCSI.
The total SCSI bus length (including internal and external SCSI cables) for each single ended SCSI bus, as shown below, must not exceed 6 meters (20 feet). Refer to Appendix A for more information.
To remove the cover of the system unit:
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. Do not turn the system on.

Figure 5-1 Opening the System Unit
To remove the top section from the system unit, perform the following steps:
Note - The unit top contains the power supply, the diskette drive, and the hard disk drive (refer to figures 5-2 and 5-3). It is the heavier of the two sections.
Figure 5-2 Open View of the SPARCstation IPC
Figure 5-3 Top View of a SPARCstation IPC
The wrist strap provides grounding between your body and the chassis for static electricity. Electric current and voltage do not pass through the wrist strap.
Caution -
To attach the wrist strap:
If an antistatic mat is not available, lay out the antistatic bag in which the hard disk drive was shipped as a work surface.
Note - Do not have the wrist strap attached and the system powered up when you handle the drive to verify the jumper settings.
Two types of drive kits can be ordered:
If you ordered a complete drive kit, the box should contain:
If you ordered a replacement drive, the kit will only contain the disk drive.
To unpack the drive:
Compare the packing list with the equipment you received.
The three sets of jumper blocks on the 1.05 Gbyte hard disk drive are located on the sides and underside of the drive. Two of the blocks are indicated below. The third block, which is on the backside of the drive and not shown in Figure 5-4, is not jumpered. You must not add any jumpers to this block.
Figure 5-4 1.05 Gbyte Hard Disk Drive Jumper Locations
As shown above, there are two sets of jumper blocks you need to check on for the 1.05 Gbyte drive:
The 1.05 Gbyte hard disk drive is a SCSI (Small Computer Systems Interface) device. Each SCSI device in your system needs a specific and unique SCSI ID.
Note - Please see the handbook appropriate for your operating system for more information about target addresses. Refer to sections in this manual regarding address selection schemes and setting jumpers.
When you set the jumpers, each drive is automatically assigned a SCSI ID number.
To verify the SCSI ID jumpers:
Do not remove the drive bracket (if attached).
If the device address jumper settings are the same as in Figure 5-5, leave them as they are.
If the settings are not the same, change them to match the settings in the figure. Use a needlenose pliers to install or remove jumpers.
Figure 5-5 Address Jumper Settings
To verify the configuration jumpers, compare the drive configuration jumper settings to the settings shown in Figure 5-6. A description of the jumper acronyms can be found on the next page.
If the jumper settings are the same as in Figure 5-6, leave them as they are.
If the jumper settings are not the same, change them to match the settings in the figure. Use a needlenose pliers to install or remove jumpers.

The SPARCstation IPC system uses a drive bracket to attach the drive to the chassis. If grommets (small, screw-type connectors) came with your drive kit, do not use them. Grommets are used to install disk drives into other SPARCstations, such as the SPARCstation 10 system.
To install a hard disk drive:
Figure 5-7 Disk Drive Mounting Bracket
Figure 5-8 Connecting the Data Cable to the Drive
To install the disk drive mounting bracket with the installed drive:
Note - The disk drive bracket must engage a securing ridge at the inside front of the unit top. If installed incorrectly, you will not be able to insert diskettes into the diskette drive.
Refer to the section, "Replacing the SPARCstation IPC Cove."
A regulated terminator is shown below.
The installation procedure for replacing a drive requires that you remove the drive bracket and the data cable from the previously installed drive to install them on the replacement drive. A drive bracket and new cable are not shipped with a replacement drive.
Caution - Do not disconnect the power cord from the system unit power outlet or from the wall outlet. This connection provides the ground path necessary to safely remove and install the hard disk drive.
To prepare a hard disk drive for replacement, you must verify that the jumpers on the drive controller board are set correctly. To gain access to the hard drive's controller board, turn the hard drive over gently on the antistatic mat. The drive controller board and the jumpers are on the bottom.
To remove a hard disk drive:
Refer to the section, "Removing the SPARCstation IPC Cover."
Refer to the section, "Attaching a Wrist Strap."
Refer to the following section, "Removing the Mounting Bracket."
The disk drive bracket resides in the top part of the system unit in front of the power supply (refer to Figure 5-9). It houses both the diskette drive supplied with the unit and an optional hard disk drive. You must remove the disk drive mounting bracket before removing either the diskette drive or hard drive.
Figure 5-9 Disk Drive Mounting Bracket
To remove the disk drive mounting bracket:
The power cord should be attached to the system unit and to the wall outlet.
Press the clip on the plug to release it from the main logic board.
Note - When pulling up on pull tabs, brace the main logic board near the socket to minimize board flex.
Figure 5-10 Detail of Disk Drive Mounting Bracket
The data cables can remain connected to the hard drives.
To replace the SPARCstation IPC cover:
Note - The interlock hooks do not engage until the unit is lowered to a 45 degree angle. Continue to hold the cover with your hands.
As you lower the unit top, continue to push back to secure the connection. The unit top will rest slightly forward. Push it gently back a few millimeters. As the unit top moves back, the latch buttons should click, securing the unit top to the unit bottom.
Figure 5-11 Closing the System Unit
Attach the lock block by inserting the PEM screw through the block on the outside, the security loop on the inside, and into the power supply. Tighten the screw with a screwdriver. Be careful not to overtighten the screw.
See the installation manual that came with your External Storage Devices for further instructions.
Refer to the system, "Restoring Power to the System."
Turn the power switches on in the following order:
If you replaced a hard disk drive containing your operating system, you must install your operating system onto the hard disk. Refer to the software manuals that were shipped with your operating system for complete instructions.
Boot the system:
After you boot the operating system, log in at the login prompt.
For a newly installed peripheral device to work with a computer system, its device driver must be added or activated. Procedures for adding or activating a device driver differ among operating systems.
For example, if your system is running SunOS Version 4.x, you might need to modify the system kernel and make changes to the /dev directory by running the MAKEDEV command.
