3 Installing the Hardware





After installation of the SBus adapter card device driver as indicated in Chapter 2, the basic SBus Expansion Subsystem (SES) Board installation process consists of the following:

3.1 Accessing the System Board

SPARCsystem 670MP

To remove the system board in the 670MP system (12 slot office pedestal), halt the SPARCsystem or SPARCserver and then turn off power as follows:

Before you turn off the system power, you must halt the operating system or loss of data can occur. To shut down the system and give users a shutdown warning:

    1. Back up the system files and data to tape, if necessary.
    2. Notify users that the system is going down.
    3. Halt the system using the appropriate commands.
    4. Wait for the system-halted message and the boot monitor prompt.

Note - This screen display is an example only. The actual message displayed on the screen will depend on the software running on the system.

    5. Turn off the system power in this order:

Caution -

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.

    6. Label and remove all cables attached to the host system board, including the cables attached to serial ports A and B, the Ethernet, SCSI, and keyboard/mouse cables.
    7. If SBus cards are installed, label and then remove any cabling.
    8. Using a 2 mm hexagonal wrench, remove the hex-head screws that are located at each end of the system board.
    9. Move the extraction lever on the system board to the open position.
    10. Carefully remove the board from the card cage enclosure and set it on the mat.

SPARCserver 690MP

To remove the system board in the 690MP system (56-inch data center cabinet), halt the SPARCsystem or SPARCserver and then turn off power as follows:

Before you turn off the system power, you must halt the operating system or loss of data can occur. To shut down the system and give users a shutdown warning:

    1. Back up the system files and data to tape, if necessary.
    2. Notify users that the system is going down.
    3. Halt the system using the appropriate commands.
    4. Wait for the system-halted message and the boot monitor prompt, see following example:

Note - This screen display is an example only. The actual message displayed on the screen will depend on the software running on the system.

    5. Turn off the system power in this order:

Caution -

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.

    6. Use a #2 Phillips screwdriver to remove the vented rear panel.
    7. Label and then remove all cables attached to the system board, including those cables attached to serial ports A and B, the Ethernet,SCSI, and the keyboard/mouse cables.
    8. If SBus cards are installed, label and then remove any cabling.
    9. Use a 2.5 mm Allen wrench to remove the two hex-head screws that are located at each end of the system board.
    10. Move the extraction lever on the system board to the open position.
    11. Gently remove the board from the card cage enclosure and set it on the ESD mat.

3.2 Installing the Expansion Adapter Card

The expansion adapter card is an SBus card. One expansion adapter card must be installed on the system board for each SBus expansion subsystem you connect. For example, if you connect two expansion subsystems, install two expansion adapter cards.

Four SBus slots are available on the subsystem board. If two SPARC modules are installed, only three SBus slots are available. If all system board SBus slots are occupied, then one of the Sbus cards must be relocated onto the SBus expansion board to make room for the SBus expansion adapter card. Refer to "Installing SBus Cards in Deskside and Data Cabinet Systems" to remove and relocate an SBus card to the SBus expansion board if required, and to install the SBus adapter card on the system board.

3.3 Installing SBus Cards on the SBus Expansion Board

Note - A requirement of the SBus expansion subsystem is that SBus slot 0 on the expansion board be occupied.

To install SBus cards on the SBus expansion board, refer to "Installing SBus Cards in Deskside and Data Cabinet Systems".

SCSI Requirements

The SBus Expansion Subsystem is transparent to the computer system to which you have connected the subsystem. Because of this, when you are connecting multiple SCSI devices to a computer system using a SBus Expansion Subsystem, you are still limited to the parameters of the SCSI standards of the computer system to which your Expansion Subsystem is attached.

The additional ports of the SBus Expansion Subsystem do not necessarily guarantee additional SCSI ports. The System Administration Guide for your system, or your operating system documentation, should provide you with this information.

3.4 Replacing the System and SBus Expansion Boards

Caution -

Use Sun ESD kit P/N 250-1088 (or equivalent) when installing printed circuit boards in a SPARCsystem or SPARCserver. 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 or SPARCserver boards.

To replace the system or SBus expansion boards:

    1. Carefully insert the board in the proper slot in the cardcage, ensuring that the board is inserted in the card guides.
    2. Ensure that the extraction levers are extended in an upright position as you slide the board toward the backplane connectors.

    The board will not seat easily unless the levers are extended.

Caution -

Do not force any board into a slot - you can damage it. The board should insert and seat smoothly. If it binds, remove it, and inspect the cardcage slot for any obvious obstructions. Also inspect both the board and the backplane for damage. Correct the problems before you attempt to reinsert the board.

    3. Press firmly on the board rear panel to reseat the board in the connectors.
    4. Replace the screws that attach the board to the cardcage.
    5. If the system is a 670MP system, proceed to the next section.

    If the system is a 690MP, first replace the rear panel using two screws, then proceed to the next section.

3.5 Connecting the SBus Expansion Subsystem

To connect an SBus expansion subsystem to a SPARCsystem or SPARCserver:

    1. Ensure that the SBus expansion adapter card is installed in the SPARCsystem or SPARCserver.

Note - A requirement of the SBus expansion subsystem is that SBus slot 0 on the expansion board be occupied.

    2. Ensure that the optional SBus cards are installed on the SBus expansion board.

Caution -

Do not block the air vents on the side of your SPARCsystem or SPARCserver.

    3. Attach one end of the SBus expansion cable to the 96-pin connector on the SBus expansion adapter card. Attach the other end of the cable to the 96- pin connector on the SBus expansion board

    Check that both ends of the cable are firmly connected.

    4. Turn the power on (| position) in the following sequence.
      a. Monitor
      b. Peripherals attached to the SPARCsystem or SPARCserver
      c. SPARCsystem or SPARCserver
    5. Check that the banner screen is displayed. An example follows:

Note - This screen display is an example only. The actual message displayed on the screen will depend on the software running on the system.

If you installed an SBus card on the SBus expansion board and you want to boot from the device connected to it each time the board is powered up, go to the next step.

If you do not want to boot from the device connected to an SBus card installed on the SBus expansion board, boot your system in the usual manner. For complete booting instructions, refer to the installation guide for your system.

3.6 Booting from SBus Cards

Examples of bootable SBus cards are:

Caution -

An SBE/S card is not a bootable device within an SBus expansion subsystem.

You can boot from a bootable SBus card installed in an SBus Expansion Subsystem. Consult the manual accompanying your SBus card to determine if the SBus card is bootable. The following describes one example, a bootable FSBE/S card. You boot from all bootable SBus cards the same way.

In this case you are booting from an FSBE/S card that you installed in the SBus Expansion Subsystem slot 2 and the Expansion Adapter card in slot 1 of the computer system. Type the following at the ok prompt:

------------------------------------------------------------------
ok boot /iommu/sbus/SUNW,xbox@1,0/dma@2,81000/esp@2,80000/sd@0,0 ------------------------------------------------------------------

Table 3-1 lists descriptions of the syntax used:

    Table 3-1 FSBE/S Boot Syntax Description

-----------------------------------------------------------------------
syntax Description -----------------------------------------------------------------------
              
/iommu        Main logic board of your computer system
              
/sbus         Resides on the main logic board of your computer 
              system
              
              in the MMU chip (Memory Management Unit)
              
/SUNW,xbox@1  Expansion Adapter card installed in slot 1
              
/dma@2,81000  FSBE/S card installed in slot 2 of the SBus Expansion 
              
and           Subsystem
              
/esp@2,8000   
              
/sd@0,0       SCSI disk set to target #0 and connected to FSBE/S SCSI 
              
              port

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

Note - SBus cards manufactured by different suppliers may have different card SBus Expansion Subsystem codes. Therefore, you should get the proper card code from the source of the SBus card.

Error Messages

During the installation of your SBus Expansion Subsystem hardware, you may receive one or more of the following error messages

Note - Any screen reference to XBox is assumed to be a refernce to the SES Board.

Error message

----------------------------------------
Test failed, expected <# observed <#'> ----------------------------------------

Action: Review the test results and determine probable cause of error. Take steps to correct the problem and rerun the installation procedures.

Error message

-------------------
No child hardware -------------------

Explanation: The system will generate this message if there is no SBus Expansion Subsystem hardware in the system.

Action: Make sure the Sbus Expansion Subsystem cable is properly plugged in to the Expansion Adapter card and that the power is on. Retry the installation.

-------------------------------
Invalid XBox slot number <#'> -------------------------------

Explanation: When decoding a child slot address, the system found a slot out of range (0 through 2 or 3 depending on the system). The system provides the slot number that is in error.

Action: Replace the SBus card reported. If that fails, replace the Adapter card in the computer system.

Error message

---------------------------------------
Invalid FCode in SBus <# XBox at <#'> ---------------------------------------

Explanation: While probing at the child level, the system found something that isn't an FCode header. The system provides the number of the slot identified by the code. Either you have a bad SBus card or the autoconfig won't work

Action: Change the SBus card. If the problem still exists, contact your authorized Sun technical support person for assistance.

Error message

--------------------------------
Invalid FCode start byte <cr'> --------------------------------

Explanation: The probe-self command detects a bad FCode header in child FCode image. This is the result of a bad SBus card

Action: Replace the SBus card with a good SBus card.

Error message

----------------------
Nothing there <cr'> ----------------------

Explanation: The probe-self command, while in diagnostic mode, did not find the proper code present.

Action: Reset the equipment and retry the installation. If the problem still exists, check the cables to see if they are making the proper contact.

Error message

------------------------------------------------------------
The card in slot <# of SBus <# XBox uses too much address space.<cr'> ------------------------------------------------------------

Explanation: During auto-configuration the system detected a card size that was too large.

Action: Change the order of the sbus cards in the Sbus Expansion Subsystem slots. Always place the SBus cards in the slots in order of their address size. The SBus card with the largest address space requirements should be in the lowest available slot.

Error message

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Unable to clear errors for S Bus <# XBox <cr -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Explanation: A test detected errors persisting after test completion.

Action: Your system has bad hardware. Check your computer system and SBus Expansion system for problems. Either fix the hardware or exchange the bad equipment for good hardware.

Error message:
