Installing the SM100 SPARC Module



Follow the instructions in this manual to verify the version of the SunOS that is installed, unpack the shipment, and install the SPARC module on the system board. The module installation instructions are for installing a second SPARC module into a system.

Verifying the Operating System

The SM100 SPARC module is designed for installation in systems that are running SunOS Version 4.1.2 or later, Solaris 2.x, or another compatible operating system. If you have any doubts about the version you are running, do the following:

Identifying the UNIX Version of Your System

Execute the command that identifies the operating system and its version number, as appropriate for your system:

    1. Go to the handbook that came with your peripheral to find this UNIX command.
    2. See the section about verifying the system environment.
    3. Return to this book after you execute the command.

If you are not running a compatible operating system, you will need to install one before you continue.

Unpacking the Shipment

    1. Remove the components from the packing box. In addition to this guide, the shipment should include:
      a. An anti-static bag containing the SPARC module.
      b. An electrostatic discharge (ESD) kit, P/N 560-1302.

Caution -

Although P/N 560-1302, ESD kit, is packaged with the SM100 SPARC module, DO NOT use P/N 560-1302 when installing the module in a 600MP-based system.
ESD kit P/N 250-1088, containing the Sun ESD mat, is required when installing the SPARC module in a 600MP-based system.

    2. Save the packing box and packing materials in case you need to transport the module.

Do not open the bag containing the SPARC module until you are instructed to do so.

Preparing to Install the SPARC Module

Electrostatic Discharge Precautions

Caution - Circuit board components are vulnerable to damage by electrostatic discharge (ESD). An electrostatic charge can build up on the human body and then discharge when you touch a board. Such discharge can be produced by walking across a carpet and touching a board, or by other similar causes. Before handling any board, make sure you dissipate your body's charge. Touch a conductive surface of the chassis or other element connected to common earth ground to discharge the static electricity present in your body. To minimize risk of ESD damage:
o Handle board by edges only.
o Store board in antistatic bag provided.

Use Sun ESD kit P/N 250-1088 (or equivalent) when working on the 600MP System Board or the 600MP Expansion Memory Board. Sun ESD kit P/N 250- 1088 contains the Sun approved Sun ESD mat which has 0.25" of cushioning to protect underside components, prevent board flexing, and provide ESD protection. Instructions for use are printed on the mat.

Do NOT use ESD kit P/N 560-1302 when installing SPARCsystem 600MP boards. ESD kit P/N 560-1302 does not provide adequate protection for SPARCsystem 600MP boards.

Note - If installing the SM100 SPARC module in a 600MP-based system, be sure to have the Sun ESD mat and grounding strap, P/N 250-1088, available.

If installing the SM100 SPARC module in a system that is NOT a 600MP-based system, you may use the anti-static wrist strap and mat contained in P/N 560- 1302 that shipped with the SPARC module.

Shutting Down the System

Before turning off the system power, you must halt the operating system:

    1. Go to the handbook that came with your peripheral to find this procedure.
    2. See the section about shutting down the system.
    3. Return to this book after you perform the procedure.

Caution -

Turn off the power at the main AC breaker on the rear of the system before you insert or remove boards and disk drives. Then, turn off the main power at the switch on the power supply. Do not disconnect the AC power cord from its receptacle.

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 SPARCsystem 600MP. Follow the instructions printed on the ESD mat. Refer to the section, "Electrostatic Discharge Precautions" for a description of the ESD mat.
Do NOT use ESD kit P/N 560-1302 when working on SPARCsystem 600MP boards.

    1. Move the system so that you have easy access to the enclosure.
    2. Spread the anti-static mat - shiny side facing up - or Sun ESD mat (P/N 250-1088, ESD mat, is required for 600MP-based systems) in the area where you are working.
    3. If the system is a 56-Inch Data Center Cabinet, use a #2 phillips screwdriver to remove the vented, rear panel. Then, go to step 6.
    4. If the system is a 12-Slot Office Pedestal, go to step 6.
    5. If the system is a 5-Slot Office Pedestal, remove the top cover:
      a. Locate the top cover release knob. Turn the knob counter-clockwise a 1/4-turn or until you hear a click.
      b. Slide the top cover back and lift the cover off of the chassis. Set the cover aside.
    6. Label the cables, including the cables that are attached to serial ports A and B, and any cables that are connected to any SBus cards. Then, remove all of the cables.
    7. Use a 2.5 mm hexagonal allen wrench to remove the hex-socket cap screws that are located at each end of the system board. Set the four screws aside.
    8. Move the extraction lever on the system board to the open position.
    9. Gently remove the system board from the enclosure, and place it on the anti-static mat or Sun ESD mat (P/N 250-1088, ESD mat, is required for 600MP-based systems).

Installing the SPARC Module

The SM100 dual processor module is a daughter card that is installed on the MBus connector on the system board. Slot 0 must be installed; slot 1 is optional.

Note - When a SPARC module is installed in MBus slot 1, SBus slot 3 can not be used.

See Figure 1, System Board, to locate the MBus slots.

    Figure 1 System Board

Installing the SPARC Module on the System Board

To install the SPARC module in MBus slot 1 on the system board, follow the procedures in this section.

    Figure 2 Installing the Second SPARC Module in Slot 1

Installing or Replacing a Module

Remove the system board from the cardcage before proceeding. See the section entitled "Removing the System Board from the Enclosure." Visually inspect the pins in the MBus connector to make sure they are not bent before installing the module.

    1. Use the anti-static mat or Sun ESD mat (P/N 250-1088, ESD mat, is required for 600MP-based systems) and grounding strap for this procedure.
    2. Remove the slotted fillister head screws from each of the standoffs.
    3. Hold the card by the edges near the connector.
    4. Position the card over the MBus connector, ensuring that the keyed notches on the connector match the bumps on the receiving connector.
    5. Firmly but gently press the card onto the connector until seated.
    6. 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).

    Figure 3 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 with the SPARC module component wire leads.

    7. Replace the system board in the cardcage.

Installing the System Board in the Enclosure

Follow these steps to install the system board in the enclosure:

    1. Move the extraction levers on the system board to the closed position.
    2. Gently replace the board in the enclosure.
    3. Make sure the board connectors are firmly seated against the connectors on the cardcage.
    4. Use a 2.5 mm hexagonal allen wrench and replace the hex socket cap screws that secure the board to the cardcage.
    5. Reinstall all cables removed in step 6 on page 5.
    6. If the system is a 56-Inch Data Center Cabinet, use a #1 phillips screwdriver and replace the two screws that secure the vented rear panel to the enclosure. Then, go to step 9.
    7. If the system is a 12-Slot Office Pedestal, go to step 9.
    8. If the system is a 5-Slot Office Pedestal, replace the top cover:
      a. Slide the cover towards the front of the system until the tabs mate with the retaining slots at the front and rear of the system.
        b. Secure the top cover by turning the release knob clockwise a 1/4-turn or until you hear a click.
        9. Move the system to its normal operating location.
        10. Remove and store the anti-static or Sun ESD mat.

      Starting Up the System

      Follow these steps to power-up the system:

        1. Set the power switch on the chassis to the ON position.

      Note - Once Power-On-Self-Tests are completed and functional modules are recognized, the operating system will configure itself automatically to take advantage of all available processors.

        2. Boot the system using the procedure that is appropriate for your operating system:
          a. Go to the handbook that came with your peripheral to find this procedure.
          b. See the section about booting the system.
          c. Return to this book after you perform the procedure.

        Watch the boot information displayed on the screen to confirm that all processors are recognized. For a SPARCsystem 600MP running SunOS 4.x, the message would look like:

        The numbers in parenthesis, 2 x 605C, indicate the number of processors running (two), and the revision number of the SPARC module that is installed (605C).

        The mod0 entry and mod1 entry indicate the system recognizes one SM100 SPARC module (two processors), which is in MBus slot 0. If two SPARC modules were installed (four processors), the system would recognize the two modules - one in MBus slot 0 and one in MBus slot 1. Boot information displayed for two SM100 SPARC modules would include an entry for four processors: mod0, mod1, mod2, and mod3.

        3. Wait for the system to boot. When the login: prompt is displayed, log in and resume operations.
