2 Preparing to Install the 600MP Dual SuperSPARC Module

Read all of the cautions and warnings in this manual before you begin and refer to the "Tools Required" section to make sure you have the tools listed. Then verify the operating system version and boot PROM level installed, unpack the shipment, and power off the system.

2.1 Identifying the UNIX Version of Your System

Execute the appropriate command that identifies the operating system and its version number. See the operating system documentation or the Solaris 2.x Handbook for SMCC Peripherals to find this UNIX command.

The 600MP dual SuperSPARC module is designed for operation in systems that are running the Solaris operating system revision 2.3 or later (or any other compatible operating system). The Solaris 2.3 Supplement is required when using the revision 2.3 software. If you are not running revision 2.3 or later, or another compatible operating system, you must install the required software before your system can use the 600MP dual SuperSPARC modules.

Note - 600MP dual SuperSPARC modules are not supported under SunOS 4.x (Solaris 1.x). Dual SuperSPARC module (multiprocessor) configurations require the Solaris operating system revision 2.3 or later (or another compatible operating system). When using revision 2.3 of the Solaris operating system, the Solaris 2.3 Supplement is required.

2.2 Identifying the OpenBoot PROM Level of Your System

Execute the appropriate command that identifies the OpenBoot PROM level. Level 2.10 boot PROMs (or later) are required in systems using the 600MP dual SuperSPARC modules.

2.3 Unpacking the Shipment

In addition to this guide, the shipment should include:

Antistatic bag containing 600MP dual SuperSPARC modules

Disposable wrist grounding strap

Return Materials Authorization (RMA) document set
(Contained only in module upgrade shipments. Includes label for returning modules being replaced.)

Do not remove the 600MP dual SuperSPARC modules from the protective bags until you have completed all other preparations.

Save the shipping carton and packing materials. These can be used to return the exchanged modules to Sun Microsystems®, Inc.

2.4 Tools Required

To install or remove modules, you will need:

Phillips screwdriver (size #2)

Flat blade screwdriver

Allen wrench (2.5 mm)

Sun ESD mat (P/N 250-1088) for 600MP-based systems

Wrist strap

2.5 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

2.6 Shutting Down the System

Caution -

To avoid damaging internal circuits, do not disconnect or plug in any cable while power is applied to the system.

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.

5. Turn off the system power in this order:

External drives (if connected)

System unit

Monitor

If you require more specific information about turning off the system power, refer to the hardware service manual for your system.

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

2.7 Attaching the Wrist Strap

The wrist strap provides grounding for static electricity between your body and the system unit chassis.

Caution -

Boards and modules can be damaged by harmful electrical charges if you do not wear a wrist strap.

1. Wrap the adhesive side of the wrist strap firmly against your wrist twice.

Figure 2-1 Wrapping the Wrist Strap Around Your Wrist

2. Peel the liner from the copper foil at the opposite end of the wrist strap.

3. Attach

Note - For SPARCserver 600MP systems, use Sun ESD kit P/N 250-1088 (or equivalent). Instructions are printed on the antistatic mat.
