This chapter provides the information you need to remove the 1000 system
board and install or replace SuperSPARC modules on the following system:
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.
Caution -
Use the Sun ESD kit provided when performing these procedures.
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 1000 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:
-
Hold the system board only by the edges near the middle of the board
where the board stiffener is located. Do not hold the board only at the ends.
-
When removing the board from an antistatic bag, keep the board vertical
until you lay it on the Sun ESD mat.
-
Do not place the board or daughter cards on a hard surface. Use a cushioned
antistatic mat. The board connectors and components have very thin pins
that bend easily.
-
Do not use an oscilloscope probe on the components. The soldered pins are
easily damaged or shorted by the probe point.
-
Transport the board in an antistatic bag.
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 the ESD kit provided when installing integrated circuits, printed
circuit boards, and drives in a SPARCserver 1000. 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. Disconnect and set aside any cable connectors from the system board back
panel.
a. Detach the keyboard cable, network cable, SCSI cable, and any other
cables connected to the back panel.
a. Label these if necessary, and label any other cables that are similar in
appearance to avoid confusion later.
4. Remove the two screws that secure the system board to the card cage.
See Figure 5-1. Set the screws aside for later reinstallation.
5. Pull the curved ends of both extraction levers outward simultaneously to
release the board from the backplane connectors.
See Figure 5-1.

Removing the System Board
6. Holding the board by both of the extraction levers, gently slide the board
out of the card cage.
Caution -
The board is cutout on the right side, so the right side of the board
will clear the card guides before the left side.
Ensure you grip the edges of the board firmly or the board may fall and
damage components.
7. Place the board on the ESD mat or in an antistatic bag.
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 SuperSPARC or other MBus module, first remove the system
board from the card cage. See Section 5.2, "Removing the System Board from
the Enclosure."
Each system board can have two SuperSPARC modules: module A and
module B.
-
SPARC module A mounts on four standoffs on the system board.
-
SPARC module B mounts like an SBus card: the connector end rests on
standoffs, but the back panel end slides onto the lip of a back panel filler
plate.
See Figure 5-2 for SPARC module locations on the 1000 system board.

Removing a Module in Slot A
1. Unlock the four standoffs securing the module to the system board.
Pull up on the tip of each standoff to unlock. See Figure 5-3.
2. Hold the module by the edges near the connector.
3. Lift the module off the connector.
Do not "rock" the module off the connector. Ensure vertical movement of
the module during the insertion or removal process.
Caution -
The connector housing will break if the module is tilted too far.
4. Place the module on the ESD mat or in an antistatic bag.

Locking and Unlocking Standoffs
5.3.2
Removing a Module in Slot B
1. Unlock the module by pulling up the tips of the two standoffs.
Pull up the tip insert of a standoff to unlock it.
2. Hold the module by the edges near the connector and gently loosen the
module from the socket.
3. Lift the module from the socket at an angle while guiding the other side
of the module out from the back panel filler.
Each module hole rests on a small pin. Gently free the module from the back
panel filler. See Figure 5-4.
Note -
It may be necessary to remove SPARC module A or the SBus card in
slot 1 to get a firm grip on SPARC module B. A firm grip is necessary to
remove the module from the connector without breaking the connector.

Installing SPARC Module B
4. Place the SuperSPARC module on the ESD mat or in an antistatic bag.
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 or replace a SuperSPARC module, first remove the system board
from the card cage. See Section 5.2, "Removing the System Board from the
Enclosure."
The system board can have up to two SuperSPARC modules: module A and
module B.
-
A module must be installed in the slot A position.
-
A module in the second slot (B) is optional; the second slot is used only for
dual module configuration systems.
Note -
Dual module configurations require Solaris 2.2 (or later) or other
compatible operating system.
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.
To install or replace a module:
1. Unlock the standoffs for the chosen location, slot A or slot B.
Pull up on the tip of a standoff to unlock it. See Figure 5-3.
2. Open the protective packaging and take out the SuperSPARC module.
Inspect the connector for bent pins.
3. Place the SuperSPARC module on the standoffs and align the module
connector with the system board socket.
For a module in slot B, slide the back panel end (the side opposite the
connector) into place under the lip of the back panel filler panel, then
align the connector with the socket.
Ensure the holes in the board align with filler panel pins. See Figure 5-4.
Caution -
Make sure the heatsinks do not catch on the lip of the system board
back panel during installation. This will help ensure the board seats properly
in the backplane.
4. Hold the SuperSPARC module by the edges near the connector.
5. Firmly press the module down until the connector is fully seated.
Press on the module firmly but gently.
Caution -
Do not rock the module onto the socket; the plastic connector
housing may break.
6. Starting from the side opposite the connector, press each corner of the
SuperSPARC module to ensure that it rests on the collar of the standoff.
7. Press down on the tip of each standoff to lock the module in place.
To install or replace the system board in the enclosure:
Caution -
Use the Sun ESD kit provided when installing integrated circuits,
printed circuit boards, and drives in a SPARCserver 1000 system. Follow the
instructions printed on the ESD mat.
1. Carefully insert the board in the proper slot in the card cage, ensuring the
board does not slip out of the left and right card guides.
The component side of the board must face up.
2. Ensure the extraction levers are in the outward position while sliding the
board toward the backplane connectors.
See Figure 5-1. The board will not seat fully unless the levers are in this
starting position.
Caution -
DO NOT FORCE a board into a slot - you may damage the board
and system. 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. Install two screws to secure the board to the card cage.
See Figure 5-1.
5. Connect any applicable interface cables to the system board back panel.
6. Move the system to its normal operating location.
7. Remove and store the wrist strap and Sun ESD mat.
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.
Note -
Check the front panel LEDs to see if the SuperSPARC module is
installed correctly. If the two outer LEDs are ON and the middle LED is OFF,
the module is installed correctly and has passed self-test.
2. Wait for the system to boot. When the login: prompt is displayed, log
in and run /usr/kvm/prtdiag.
This will confirm that all processors are recognized and display system
information.
3. Type the command /usr/kvm/prtdiag to display system information.
For 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.
The screen display shows that the system recognizes a 50 MHz SuperSPARC
module in slots A and B of board 0, board 1, and board 2.
