This chapter provides the information you need to remove, install, or replace:
-
SPARC and SuperSPARC modules
Caution -
The 600MP system board is more fragile than previous Sun 9U
boards. The system board and its cards that install on this board have bottom-
side surface-mount components. Observe the following precautions.
1.
Hold the system board only by the edges near the middle of the board,
where the board stiffener is located. Do not flex the board or board-mounted
cards, or hold the board only at the ends. The fine-pitch surface mount
components make it sensitive to board-flexing.
2.
When you remove the board from its antistatic bag, keep the board vertical
until you lay it on the Sun ESD mat.
3.
Do not place the board or cards which install on the board on hard surfaces.
The connectors and components have very fine pins which bend easily.
Placing the board and cards on an antistatic mat will prevent damage to the
pins.
4.
Do not use a scope probe on the components. The 20-mil pitch pins are
easily damaged or shorted by the probe point.
5.
Transport the board in an antistatic bag.
Follow directions below to remove the system or expansion memory board.
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.
Caution -
The system chassis power must be turned off, and the power cord
must remain plugged in to ensure a proper ground.
1. Access the card cage as shown in Chapter 1 of the enclosure service
manual provided with the system.
2. Unfasten and set aside any cable connectors from the board back panel.
To remove the system board, first detach the keyboard, ethernet, and other
back panel connectors. Label these if necessary.
To remove an expansion memory board, no external connectors need to be
removed.
3. Remove the four screws securing the board to the card cage.
Set the screws aside for later reinstallation.
4. Move the tabs on the extraction levers outward to release the board from
the backplane connectors. Place the board on the ESD mat or in an
antistatic bag.
If not installing or removing SIMMs or cards on the board, turn to Section 2.9,
"Installing or Replacing a Board in the Card Cage" for replacement
instructions.
Remove the system board from the card cage before proceeding. See Section
2.2, "Removing a Board from the Card Cage."
1. Remove the slotted fillister head screw from each standoff securing the
module.
Keep these screws to reuse when installing the replacement module. See
Figure 2-1.
2. Hold the module by the edges near the connector.
3. Lift the module off the connector.
4. Place the module on the ESD mat or in an antistatic bag.
Figure 2-1
Removing or Installing the 600MP Single SPARC or SuperSPARC Module
To install or replace a module, first remove the system board from the card
cage. Refer to Section 2.2, "Removing a Board from the Card Cage."
Note -
Visually inspect the pins on the module and in the MBus connector to
ensure they are not bent before installing the module.
1. Remove the slotted fillister head screws from each of the standoffs.
Ensure that the standoffs are in the MBus slot location when installing a
module in MBus slot 1. Move the two standoffs from the SBus slot 3 location
to the MBus slot 1 location if necessary.
2. Open the protective packaging and remove the module.
3. Hold the module by the edges near the connector.
4. Position the module on the four screw-in standoffs.
Ensure the module is seated on the four standoffs. See Figure 2-1.
5. Align the module on the MBus connector, ensuring that the keyed notches
on the connector match the bumps on the receiving connector. Firmly but
gently press down until the module is fully seated on the connector.
Do not "rock" the module onto the connector. Ensure vertical movement of
the module during the insertion or removal process.
6. Starting from a corner opposite from the connector, press down on the
corner of the module.
Repeat this step on the remaining corners.
7. Replace the slotted fillister screws on the four standoffs and tighten.
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. Refer to Figure 2-7.
Figure 2-2
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.
8. Proceed to Section 2.9 to replace the system board in the card cage.
Remove the system board from the card cage before proceeding. See Section

Next, remove the module(s) being replaced. Refer to the appropriate section:
Proceed to the appropriate section referenced below according the module type
being replaced:
The 600MP dual SuperSPARC module has mounting rails attached. Screw-in
standoffs previously used to mount single modules cannot be used. After
removing installed modules from the board, remove the four standoffs for each
slot.
Caution -
Use Sun ESD kit P/N 250-1088 (or equivalent) when installing
integrated circuits, printed circuit boards, and drives in a SPARCserver 600MP.
ESD kit P/N 250-1088 contains the Sun approved ESD mat that has 0.25-inch
cushioning to protect underside components, prevent board flexing, and
provide ESD protection.
Follow instructions printed on the ESD mat and use the wrist grounding strap.
If you are installing dual SuperSPARC modules for the first time on the board
in question, follow the step below to remove the standoffs.
Unscrew and remove the screw for each standoff.
Remove screws that secure the standoffs from the underside of the board.
There are four standoffs for slot 0 and four for slot 1. See Figure 2-4.
Note -
Keep these screws for reuse. They will secure the dual SuperSPARC
module mounting rails to the board when installing the module.
Proceed to Section 2.6.2, "Identifying Modules."
Figure 2-4
Removing Single SPARC or SuperSPARC Module Standoffs
There are two 600MP dual SuperSPARC modules: one module installs in slot 0
only, the other module installs in slot 1 only. Connectors and preinstalled
mounting rails on the two modules are in different locations, so the modules
are slot specific and are not interchangeable.
Hold the dual SuperSPARC module with the components facing you and the
MBus connector pointing toward the floor. The slot 0 module has the connector
on the right; the slot 1 module has the connector on the left (see Figure 2-5).
Mounting rail holes align with holes on the system board (Figure 2-6).
