This chapter provides the information you need to remove the 600MP or 2000 system board and install or replace SuperSPARC modules on the following systems:

Warning -

Procedures contained in this chapter must be performed by qualified service-trained maintenance providers.
See the section entitled "Notes, Cautions, and Warnings" found in the Preface of this manual.

Caution -

Individuals who remove any outer panels or open covers to access this equipment must observe all safety precautions and ensure compliance with skill level requirements, certification, and all applicable local and national laws.

3.1 Handling System Boards and Assemblies

Caution -

DO NOT use ESD kit P/N 560-1302 when working on 600MP system boards. Use Sun ESD kit P/N 250-1088 (or equivalent). Instructions are printed on the ESD mat.

Caution -

The system chassis power must be turned off and the AC power cord must remain plugged in to ensure a proper ground.

Caution -

The 600MP and 2000 system boards, modules, and cards have surface-mount components that may break when the board is flexed.

To minimize the amount of board flexing, observe the following precautions:

3.2 Removing the System Board from the Enclosure

Caution -

See the "Shutting Down the System" section in Chapter 2 to make sure the system is shut off. Turn off the power at the main AC breaker before you insert or remove boards and disk drives. Do not disconnect the AC power cord from its receptacle. The system chassis power must be turned off, and the power cord must remain plugged in to ensure a proper ground.

Caution -

Use Sun ESD kit P/N 250-1088 (or equivalent) when installing integrated circuits, printed circuit boards, and drives in a SPARCserver 600MP. Sun ESD kit P/N 250-1088 contains the Sun approved ESD mat that has 0.25" of cushioning to protect underside components, prevent board flexing, and provide ESD protection. Instructions for use are printed on the mat.

To access the system board:

    1. Move the system so that you have easy access to the board enclosure.
    2. Place the ESD mat in the area where you are working.

    The ESD mat and the wrist grounding strap will protect against electrostatic discharge. Connect the ground clip to the chassis and mat.

    3. Open the board enclosure.

    There is no panel or cover to remove to access the board in a 12-slot system.

Caution -

Attach the wrist grounding strap that came with the module.

    4. Disconnect and set aside any cable connectors from the system board back panel.
      a. Detach the keyboard, Ethernet, and other back panel connectors. Label these if necessary.
      b. Label all cables that are attached to serial ports A and B, and any that are connected to SBus cards. Disconnect and remove all of the cables.
    5. Use a 2.5 mm Allen wrench to remove the screws securing the board to the card cage.

    Set the screws aside for later reinstallation.

    6. Pull the curved ends of the extraction levers outward to release the board from the backplane connectors.
    7. Gently remove the system board from the enclosure.

    Place the board on the Sun ESD mat.

Caution -

Make sure the bottom of the board does not touch adjacent cards and filler panels.

3.3 Removing Modules

To remove a SuperSPARC or other MBus module, first remove the system board from the card cage. See Section 3.2, "Removing the System Board from the Enclosure."

Caution -

Use Sun ESD kit P/N 250-1088 (or equivalent) when installing integrated circuits, printed circuit boards, and drives in a SPARCserver 600MP. ESD kit P/N 250-1088 contains the Sun approved ESD mat that has 0.25" of cushioning to protect underside components, prevent board flexing, and provide ESD protection.

Follow the instructions printed on the ESD mat and use the wrist grounding strap.

Warning -

The heatsinks on the SuperSPARC modules may be hot. Use caution when removing or installing SuperSPARC modules and avoid contact with the heatsinks. Hold SuperSPARC modules only by the edges.

To remove a module:

    1. Remove the slotted fillister head screw from each standoff.

    Each module should be mounted on four standoffs.
    Keep the four screws to use when installing a replacement SuperSPARC module.

    2. Hold the module by the edges near the connector.
    3. Lift the module off the connector.

    Do not "rock" the module off of the connector. Ensure vertical movement of the module during the insertion or removal process.

    4. Place the module on the ESD mat or in an antistatic bag.

Follow the steps in "Installing or Replacing Modules" to install a SuperSPARC module.

3.4 Installing or Replacing Modules

To install or replace a SuperSPARC module, first remove the system board from the card cage. See Section 3.2, "Removing the System Board from the Enclosure."

The system board can have up to two SuperSPARC modules:

A module must be installed in the slot 0 or slot A position.
A module in the second slot (1 or B) is optional; the second slot is used only for dual module configuration systems.

Note - Dual module configurations using modules in the SMxx SPARC module family are not supported under SunOS 4.x (Solaris 1.x). Dual module configurations require Solaris 2.1 (or later) or other compatible operating system. SMxx represents a SPARC module from a series of modules that begins with SM20.
See Table 2-1 on page 2 of Chapter 2 for software requirements specific to your system.

Caution -

Use the wrist grounding strap that came with the module.

Note - Visually inspect the pins on the SuperSPARC module and in the MBus connector to make sure the pins are not bent before installing the module.

Note - When a SuperSPARC module is installed in slot 1 on the 600MP system board, SBus slot 3 cannot be used.

Warning -

The heatsinks on the SuperSPARC modules may be hot. Use caution when removing or installing SuperSPARC modules and avoid contact with the heatsinks. Hold SuperSPARC modules only by the edges.

To install a module:

    1. Remove the slotted fillister head screw from each standoff.

    Each module should be mounted on four standoffs.
    When installing a module in slot 1 on the 600MP system board, you must first move the two standoffs used for SBus slot 3 to the MBus slot 1 location.

    2. Open the protective packaging and take out the SuperSPARC module.
    3. Hold the card by the edges near the connector.
    4. Place the module on the four standoffs.

    Make sure the module is seated on the standoffs.

    5. Align the module on the module connector, ensuring that the keyed notches on the connector match the bumps on the receiving connector. Firmly but gently press down until the module is fully seated on the connector.

    Do not "rock" the module onto the connector. Ensure vertical movement of the module during the insertion or removal process.

    6. Starting from a corner opposite from the connector, press down on the corner of the module.

    Repeat this step on the remaining corners.

    7. Replace and fasten the slotted fillister screws on the four standoffs.

Note - Do not substitute pan head screws for the fillister head screws originally removed from the standoffs. Fillister head screws must be used because the head on a fillister head screw is taller. See Figure 3-5.

    Figure 3-4 Fillister Head and Pan Head Screws

Caution -

Because of the tight clearance, use caution when replacing the fillister head screws. Do not allow the screwdriver to contact the SuperSPARC module.

3.5 Installing the System Board in the Enclosure

Caution -

Use Sun ESD kit P/N 250-1088 (or equivalent) when installing integrated circuits, printed circuit boards, and drives in a SPARCserver 600MP. Follow the instructions printed on the ESD mat. See the "Electrostatic Discharge Precautions" section in Chapter 2 for a description of the ESD mat.

    1. Carefully insert the board in the proper slot in the card cage, ensuring that the board does not slip out of the upper and lower card guides.

    The component side of the board must face to the right.

    2. Ensure that the extraction levers are in the outward position as you slide the board toward the backplane connectors.

    The board will not seat fully unless the levers are in this starting position.

Caution -

DO NOT FORCE any board into a slot - you may damage it. The board should insert and seat smoothly. If it binds, remove the board and inspect the card cage slot for any obvious obstruction. Also inspect both the board and the backplane for bent pins or other damage. Correct the problems before attempting to reinsert the board.

    3. Press firmly on the board rear panel to seat the board onto the backplane connectors.

    The extraction levers should swing into the locked position.

    4. Use a 2.5 mm Allen wrench to replace the screws that secure the board to the card cage.
    5. Reinstall all cables disconnected in Section 3.2, "Removing the System Board from the Enclosure."
    6. Close the board enclosure.
