3 Installing or Replacing a 1.3 GB IPI Disk Drive



This chapter supplies the information necessary to install or replace a 1.3 GB IPI disk drive within an IPI tray.

Warning -

Do not proceed with this chapter unless you have already prepared your system for service according to the instructions given in Chapter 1, "Preparing the System for Service

To install a 1.3 GB IPI disk drive in an IPI tray, follow the instructions given in Section 3.2, "Installing a 1.3 GB IPI Disk Drive."

To replace a 1.3 GB IPI disk drive in an IPI tray, first follow the instructions given in Section 3.1, "Removing a 1.3 GB IPI Disk Drive." Then follow the instructions given in Section 3.2, "Installing a 1.3 GB IPI Disk Drive."

Note - There are systems in the field that differ from the majority of production units in several minor details. When these differences affect the remove-and-replace procedures, this text covers both the standard and the variation.

3.1 Removing a 1.3 GB IPI Disk Drive

Follow the directions given in the following sections to remove a 1.3 GB IPI disk drive from the 1.3 GB IPI tray.

3.1.1 Extending the Tray and Removing the Cover

Follow these directions to extend a 1.3 GB IPI tray from the cabinet and remove the top cover from the tray:

    1. Move to the rear of the cabinet and loosen the two captive screws securing the tray cover at the rear of the cabinet.
    2. Unscrew the two screws that secure the tray to the left slide rail (Figure 3-1).

    Repeat this step for the right slide rail.

    Figure 3-1 Removing the Screws at the Rear of the Tray

    3. Move to the front of the cabinet and unscrew the two screws that secure the front of the tray to the cabinet.
    4. Extend the tray fully until the slide rail button clicks.

Caution -

In order to accomplish the next step of removing the top cover, you may have to press the slide rail button a second time and extend the tray an inch or two past the latched position. Exercise extreme caution if you find you must extend the tray past the latched position, since the tray may come completely out of the cabinet if you extend it too far.

    5. Loosen the remaining top cover captive screws (three on each side and two on the front) and remove the cover.

Note - If you had to extend the tray past the latched position to remove the top cover, slide the tray back into the cabinet until you hear the tray click into place after you have removed the cover.

3.1.2 Removing the Disk Drive from the Tray

Caution -

Be sure you're grounded with a grounding wrist strap.

Follow these instructions to remove a 1.3 GB IPI disk drive from an IPI tray:

    1. If you have not already removed the top cover from the 1.3 GB IPI tray, loosen the ten top cover screws (three on each side and two on the front and back) and remove the cover.
    2. Disconnect the data, power, and address switch cables from the drive.

    To disconnect the cables, pivot the ejectors on the connector down, applying equal force to both ejectors (see Figure 3-2).

    Figure 3-2 Proper Disconnecting Procedure

    3. Loosen the two captive screws securing the drive to the bottom of the tray.
    4. Remove the drive by sliding it towards the power supply to free the opposite end from the lip-retainers.
    5. Using the handle, raise the drive free and remove it from the tray.

Repeat this procedure for every 1.3 GB IPI disk drive you want to remove from the tray.

Note - If you are removing the rear drive(s) from the 1.3 GB IPI tray so that you can remove the tray from the cabinet, after you have removed the drive(s), press the button in the center slide rail and pull the tray away from the cabinet to dismount it from the slide rails. If you want to replace the drives after you have removed the 1.3 GB IPI tray, follow the instructions given in Section 3.2.3, "Installing a 1.3 GB IPI Disk Drive."

3.2 Installing a 1.3 GB IPI Disk Drive

Follow the instructions in these sections to install a 1.3 GB IPI disk drive.

3.2.1 Unpacking the Drives

Caution -

Do not expose the device(s) within the IPI tray to sudden temperature or humidity change. Such exposure could cause condensation within the drives which could damage the drives. At the installation site, allow the devices to remain in their packing containers until their temperature matches that of the surrounding air. Use the following as a guide to time allowed before unpacking the devices based upon the temperature of the device upon receipt:

---------------------------------------------------------------------

Caution -

Store or transport the IPI tray and individual drives in the right- side up position only. Do not jostle the trays or bump the drives when moving them. Do not tilt the tray to extremes when unpacking them. Such physical shock or incorrect positioning can damage the drives.

3.2.2 Inspection and Handling

After unpacking the 1.3 GB IPI disk drive, inspect it for evidence of damage. If damaged, keep all contents and packing materials for the carrier's agent to inspect. Save packing materials for future use.

Caution -

A 1.3 GB IPI disk drive is an electromechanical device that may be damaged by excessive physical shock. Do not jar this device or drop it. A 1.3 GB IPI disk drive should be handled only by service personnel who are familiar with the correct methods of working with IPI devices.

Note - An "Electro Static Discharge (ESD) Kit" is included with many options and upgrades shipped separately from the original system. This kit includes a wrist grounding strap which provides grounding between your body and the chassis ground. The kit also includes a Sun ESD mat on which to place the unit to prevent static charge from accumulating in the device.

Caution -

Connection to earth-ground must be provided to guard against damage to devices. Verify the cabinet power cord is connected to facilities power via plug receptacle or pigtail connection as appropriate. Ensure the facilities breaker serving the cabinet is OFF.

You may also want to verify that the dip switches at the rear of the 1.3 GB IPI disk drive were set correctly before you install the drive. Appendix A of this manual gives you the correct dip switch settings for the 1.3 GB IPI disk drive.

3.2.3 Installing a 1.3 GB IPI Disk Drive

The 1.3 GB IPI drives are installed in a tray with two, three or four drives to a tray. Follow these instructions to install a 1.3 GB IPI disk drive in an IPI tray:

    1. Using the drive handle located at the middle of the unit, position the 1.3 GB IPI drive in the tray such that the two captive screws can be tightened to secure the drive to the bottom of the tray.
    2. Connect the data cables to the drive (see Figure 3-3).

    Figure 3-3 Data Cabling in the Tray

Note - To connect the cables to the drive, pivot the connector latches up to lock the connector into place (see Figure 3-4).

    Figure 3-4 Proper Connecting Procedure

    3. Connect the power cable to the drive (see Figure 3-5).

    Figure 3-5 DC Harness Cabling in the Tray

    4. Connect the address switch cables to the drive (see Figure 3-6).

    Figure 3-6 LED/Address Cabling in the Tray

    5. Move to the front of the tray and set the IPI address for the drive.

    There are four IPI address switches at the front of each tray, one for each drive within the tray. The addresses range from 0 to 7. Figure 3-7 shows the location of the IPI address switches on the 1.3 GB IPI tray.

    Figure 3-7 Location of the IPI Address Switches on the 1.3 GB IPI Tray

To set the IPI address for the 1.3 GB IPI disk drive, press the button marked "+" to increment the address shown, or press the button marked "-" to decrement the address shown until you see the proper address in the window. Table 3-1 gives the IPI addresses for the 1.3 GB IPI drives within the 56" Data Center Cabinet, and Table 3-2 gives the IPI addresses for the 1.3 GB IPI drives within the 56" Data Center Expansion Cabinet.

    2. Screw in the eight top cover screws that are accessible from the front of the tray.
    3. Fully slide the tray back into the cabinet.
    4. Screw in the two screws that secure the front of the tray to the cabinet.
    5. Move to the rear of the cabinet and screw in the two screws securing the top cover at the rear of the tray.
    6. Screw in the four screws that secure the back of the tray to the slide rail.

3.2.5 What's Next
