2 Installing the SBE/S SBus Card



Make sure that only qualified personnel perform this installation procedure.

Follow the instructions to verify the version of the operating system that is installed, unpack the shipment, and install the SBus card on the 600MP system board.

This chapter refers to installation procedures for SPARCsystem 600MP series products. If you intend to install the SBE/S card in another system, check with your Sun sales person to first determine that the other system supports SBE/S. If so, follow the SBus installation procedure shipped with that system.

2.1 Verifying Your Version of SunOS

The SBE/S SBus card 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, 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 the system is not running a compatible operating system, you must install one before you can continue.

2.2 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 SBE/S SBus card and the cables.
      b. An electro-static discharge (ESD) kit.
    2. Save the packing box and packing materials in case you need to transport the card.

Do not open the bag containing the SBus card until you are instructed to do so.

2.3 Preparing to Install the SBE/S SBus Card

The SBE/S SBus card can be installed in any SBus slot on the system board.

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.

Caution -

Make sure that the springfingers on the PC board are not shorted against any ungrounded part of the SBus card. Shorting active components to the springfingers can cause severe damage to the SBus card and/or the system.

In some SBus card installations, the SBus cards are mounted close to the springfingers. If the springfingers only make contact with a grounded connector shell on the SBus card, no insulator shield is required. Otherwise, inspect the space between the springfingers and components on the SBus card. Remember that the springfingers may be compressed (that is, closer to the SBus card) when the system board is installed. If there is any possibility of contact, install an insulating shield on the SBus card.

Note - The installation instructions in this document are specific for installing SBus cards in SPARCsystem 600MP systems. If you are installing SBus cards in other Sun systems, refer to the installation instructions provided with the system.

2.4 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.
    4. After the system has halted, use the power switch to turn off the system power.

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.

2.5 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.
