This chapter supplies the information necessary to install or replace a 1.3 GB 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 tray, follow the instructions given in Section 2.2, "Installing a 1.3 GB IPI Tray."

To replace a 1.3 GB IPI tray, first follow the instructions given in Section 2.1, "Removing a 1.3 GB IPI Tray." Then follow the instructions given in Section 2.2, "Installing a 1.3 GB IPI Tray."

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.

2.1 Removing a 1.3 GB IPI Tray

Note - If you are removing a tray with three or four 1.3 GB IPI disk drives installed in it, you must first remove the drive(s) from the rear of the tray before you can remove the tray. Follow the directions given in Section 3.1, "Removing a 1.3 GB IPI Disk Drive," to remove the 1.3 GB IPI disk drive(s) from the rear of the 1.3 GB IPI tray and to remove the tray from the cabinet.

If you have only two drives installed in your 1.3 GB IPI tray, follow these instructions to remove the tray:

    1. Move to the rear of the cabinet and unscrew the two screws that secure the tray to the left slide rail (Figure 2-1).

    Repeat this step for the right slide rail.

    Figure 2-1 Removing the Screws at the Rear of the Tray

    2. Move to the front of the cabinet and unscrew the two screws that secure the front of the tray to the cabinet.
    3. Extend the tray fully until the slide rail button clicks.
    4. Press the button in the center of the slide rail and pull the tray away from the cabinet to dismount it from the slide rails.

2.2 Installing a 1.3 GB IPI Tray

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

2.2.1 Unpacking the Tray

Caution -

The tray shipping weight with power supply and four 1.3 GB IPI disk drives is approximately 75 pounds (34.5 kg). Use safe lifting procedures when unpacking and installing the tray to prevent damage to the equipment or injury to personnel.

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 table as a guide to time allowed before unpacking the devices based upon the temperature of the device upon receipt:

+/- 60                                  +/- 33.3     8

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

Store or transport the IPI tray and individual drives in the right-side up position only or damage to drives may occur. 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.

2.2.2 Inspection and Handling

After unpacking the tray, 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 installed inside an IPI tray 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.

2.2.3 Installing the Slide Rails in the Cabinet

Note - If you already have slide rails for a 1.3 GB IPI tray installed in your cabinet, you can skip this section and begin reading Section 2.2.4, "Installing the Tray Assembly."

Follow these steps to install the slide rails in the cabinet:

    1. Locate the slide rails at the sides of the 1.3 GB IPI tray.
    2. Take one slide rail and extend it fully until it locks.
    3. Depress the button in the rail center.

    This action releases the two-part portion.

    4. Continue extending the rail until it is separated from the rail mounted to the tray.
    5. Select the correct mounting holes to use for the tray assembly.

    The mounting holes are numbered up from the bottom beginning with one, and are stamped on the rail face at decade increments (10, 20, and so on).

    Table 2-1gives the correct mounting holes for each tray assembly for the 56" Data Center Cabinet, and Table 2-2 gives the correct mounting holes for each tray assembly for the 56" Data Center Expansion Cabinet.

Seventh tray         Holes 67 and 68
                     
Eighth tray          Holes 77 and 78

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

Note - If you have 1 GB or 911 MB IPI disk drives already installed in your cabinet, each set of drives (one or two drives) will take up as much vertical room as a single 1.3 GB IPI tray, so you can count each set of 1 GB or 911 MB IPI disk drives installed in your system as a single 1.3 GB IPI tray. For example, if you have four 1 GB IPI disk drives installed in your 56" Data Center Expansion Cabinet, these four 1 GB IPI disk drives would take up as much vertical room as two 1.3 GB IPI trays, which would mean that the correct mounting holes for the first 1.3 GB IPI tray for your system would be holes 25 and 26 (see Table 2-2). Position the two-part portion of the rail (with the bent bracket) in the chassis and orient it correctly to the hole positions (see Figure 2-2).

    Figure 2-2 Securing the Slide Rails in the Cabinet

    6. Loosely install mounting screws for each slide rail by following these steps:
      a. In the front of the rail, loosely install two 10-32 screws each for the left and right slide (do not tighten).
      b. In the back of the rail, loosely install two 10-32 screws each for the left and right slide (do not tighten).

Caution -

Use only SAE 10-32 screws to secure the slide rails to the cabinet mounting rails. Using any other screw type will damage the mounting rails.

    7. With the slide rails installed and positioned correctly, hold them securely against the rack mounting rails and tighten all the screws at the front and the rear securely.

Repeat this procedure for each slide rail you want to install.

2.2.3.1 Removing the Slides from the Cabinet

If rails need to be removed, remove the tray as appropriate and remove the rail(s) by performing the steps above in reverse order.

2.2.4 Installing the Tray Assembly

Caution -

If you are installing a tray with four drives, you must remove the two rear drives before you can install the tray. Follow the instructions given in Section 3.1.2, "Removing the Disk Drive from the Tray," to do this, then return here.

Mount the tray(s) on the slide rails using the following procedure:

    1. Push both slide rails completely back into the cabinet.
    2. Position the tray assembly on the rails and slide towards the cabinet until you hear a "click."

Note - Install the first tray assembly on the bottom-most rails, the second tray assembly on the next higher rails, and so on.

Note - If you removed drives to install the 1.3 GB IPI tray, follow the instructions given in Section 3.2.3, "Installing a 1.3 GB IPI Disk Drive" to install the drives in the tray again.

    3. Extend the tray slightly to expose the button in the center rail.
    4. Press the button in the center rail and push the tray completely in the cabinet.
    5. Loosely install two 10-32 screws at the front of the tray (one on each side, as shown in Figure 2-3).

    Figure 2-3 Securing the Tray Assembly in the Cabinet

    6. Loosely install four 10-32 screws at the rear of the tray (two on each side, as shown in Figure 2-4).

    Figure 2-4 Securing the Tray Assembly in the Cabinet

    7. Tighten all six screws at the front and rear of the tray securely.

Repeat these procedures for each tray assembly you want to install.

2.2.5 Connecting the Power Cord

Follow these instructions to connect the power cord to the 1.3 GB IPI tray:

    1. Locate the power cord for the 1.3 GB IPI tray.
    2. Connect the female end of the power cord to the power receptacle at the rear of the 1.3 GB IPI tray you just installed.

    Figure 2-5 shows the location of the power receptacle for the tray.

    Figure 2-5 I.3 GB IPI Tray Power Receptacle

    3. Route the power cord for the tray you are installing down the right side and along the bottom of the cabinet.

    Figure 2-6 shows the routing of the power cords for a fully-loaded 56" Data Center Expansion Cabinet.

    Figure 2-6 Power Cord Routing for a 56" Data Center Expansion Cabinet

    4. Route the power cord up through the cut-out to the power sequencer at the left side of the cabinet.
    5. Plug the power cord for the tray into the power sequencer (see Figure 2-7).

    Figure 2-7 Plugging the Tray into the Power Sequencer

    Figure 2-8 shows which receptacle on the power sequencer you should plug your tray into for the 56" Data Center Cabinet, and Figure 2-9 and Figure 2-10 show which receptacle on the power sequencer you should plug your tray into for the 56" Data Center Expansion Cabinet.

    Figure 2-10 Connections for a 56" Data Center Expansion Cabinet (240V International Power Sequencer)

    6. Tuck the extra length of the power cord down the pocket beneath the power sequencer.

    Repeat this procedure for every tray you installed.

2.2.6 Cabling the Tray

The cabling procedures for the 1.3 GB IPI tray depends on the position of the tray in the daisy-chain and whether or not your system already has 1 GB or 911 MB IPI disk drives installed.

Note - You can only have a maximum of eight IPI disk drives connected to each ISP-80 disk controller, so you must install a new ISP-80 disk controller for every eight IPI disk drives you have installed in your system.

2.2.6.1 Cabling Between 1.3 GB IPI Trays and 1 GB or 911 MB IPI Disk Drives

Note - To support new 1.3 GB IPI disk drives as add-on options to existing systems, new ISP-80 controller-enhanced firmware is required (see Section 1.2, "System Requirements," for more information).

New ferrite-choke controller cables (special shielded cables) may also be used, but are not required for add-ons to the 56" Data Center Cabinet or 56" Data Center Expansion Cabinet (the new ferrite-choke controller cables can be recognized by a short cylinder near the connectors at each end of the cable). The existing 56" Data Center Cabinet controller cables may be mixed with the new ferrite-choke controller cables.

Follow these instructions to cable between a 1.3 GB IPI tray and either a 1 GB IPI disk drive or a 911 IPI disk drive:

    1. Remove the terminator from the connector marked "OUT" on the rear of the last 1 GB or 911 MB disk in the daisy-chain (see Figure 2-11).

    Figure 2-11 "OUT" Connector on a 1 GB or 911 MB IPI Disk Drive

    2. Locate the .45-meter IPI data cable.
    3. Connect one end of the .45-meter IPI data cable to the connector marked "OUT" on the last 1 GB or 911 MB disk drive in the daisy-chain (see Figure 2-11).
    4. Connect the other end of the .45-meter IPI data cable to the connector marked "IN" on Port A of the 1.3 GB IPI tray you just installed (see Figure 2-12).
