This chapter provides the information you need to:
-
Access and remove the 600MP system board from the cabinet
-
Remove installed SuperSPARC modules
-
Remove the four mounting standoffs from the system board
-
Install 600MP dual SuperSPARC modules
Warning -
Procedures contained in this chapter must be performed by
qualified service-trained maintenance providers.
See the section entitled "Notes, Cautions, and Warnings" 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 -
DO NOT use ESD kit P/N 560-1302 when working on 600MP
system boards. Use Sun ESD kit P/N 250-1088 (or equivalent). 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 600MP 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 SunŽ ESD mat.
-
Do not place the board or 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 Sun ESD kit P/N 250-1088 (or equivalent) when installing
integrated circuits, printed circuit boards, and drives in a SPARCserver 600MP.
Sun 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. 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 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. Open the board enclosure.
-
If the system is a 56-inch data cabinet, use a #2 Phillips screwdriver to
remove the vented, rear panel. See Figure 3-1. Then, go to step 4.
-
If the system is a 12-slot office pedestal, go to step 4.
There is no panel or cover to remove to access the board in a 12-slot system.
-
If the system is a 5-slot office pedestal, remove the top cover:
-
Locate the top cover release knob and turn the knob counterclockwise one
quarter turn or until you hear a click. See Figure 3-2.
-
Slide the top cover back and lift the cover off the chassis.
-
Set the cover aside. Go to step 4.

Caution -
Be sure you have attached the wrist grounding strap.
4. Disconnect and set aside any cable connectors from the system board back
panel.
a. Detach the keyboard, Ethernet, and other back panel connectors. Label
these if necessary.
b. Label all cables that are attached to serial ports A and B, and any that
are connected to any SBus cards. Disconnect and remove all of the
cables.
5. Use a 2.5 mm Allen wrench to remove the screws securing the board to the
card cage.
Set the screws aside for later reinstallation.
6. Pull the curved ends of the extraction levers outward to release the board
from the backplane connectors.
7. Gently remove the system board from the enclosure.
Place the board on the Sun ESD mat.
Caution -
Make sure the bottom of the board does not touch adjacent cards
and filler panels.
To remove a SuperSPARC or other MBus module, first remove the system
board from the card cage. See Section 3.2, "Removing the System Board from
the Enclosure."
The 600MP dual SuperSPARC module has mounting rails attached, so the
screw-in standoffs previously used to mount SuperSPARC modules cannot be
used. After removing installed modules from the system board, you must also
remove the four standoffs for each slot. The screws that attach the standoffs to
the system board should be used to attach the mounting rails when you install
the 600MP dual SuperSPARC modules.
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 the instructions printed on the ESD mat and use the wrist grounding
strap.
3.3.1
Removing Modules
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.
1. Remove the slotted fillister head screw from each standoff. See Figure 3-3.
Figure 3-3
Removing SuperSPARC Modules and Standoffs
2. Hold the module by the edges near the connector.
3. Lift the module off the connector.
Do not "rock" the module off of the connector. Ensure vertical movement of
the module during the insertion or removal process.
4. Place the module on the ESD mat or in an antistatic bag.
3.3.2
Removing Standoffs
Unscrew and remove the screw for each standoff.
Screws on the underside of the system board attach the standoffs to the
board.
There are four standoffs for slot 0 and four standoffs for slot 1. See Figure 3-3.
Note -
Keep these screws. You will need them for the mounting rails when you
install the dual SuperSPARC modules.
Note -
When installing a module in slot 1, you must also remove any SBus
cards and standoffs used for SBus slot 2 and SBus slot 3.
Note -
Dual SuperSPARC module configurations require the Solaris operating
system, revision 2.3 (or later), or another compatible operating system. The
Solaris 2.3 Supplement is required when using the Solaris revision 2.3 software.
Note -
Level 2.10 boot PROMs (or later) are required for systems using the
600MP dual SuperSPARC modules. If lower level boot PROMs are installed in
your system, you must upgrade the boot PROMs before you can use the dual
SuperSPARC modules.
There are two 600MP dual SuperSPARC modules: one dual module can be
installed only in slot 0, and the other dual module can be installed only in slot
1. The connectors and preinstalled mounting rails on the two modules are in
different locations, so the modules are slot specific and are not interchangeable.
When you 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, and the slot 1 module has the connector on the left. See
Figure 3-4.
The mounting rail holes (Figure 3-5) line up with the holes on the system board
where the four standoffs for each slot were installed.
Installing or replacing dual SuperSPARC modules requires:
Note -
Because 600MP dual SuperSPARC modules are shipped with mounting
rails attached, the screw-in standoffs on the system board must be removed.

The module will have two mounting rails attached to the underside.
2. Hold the module by the edges near the connector.
Make sure the mounting rails face down toward the system board.
3. Line up the module mounting rails with the four holes on the system
board where the standoffs were inserted. See Figure 3-6.
Each mounting rail has two holes. The top mounting rail, which straddles
the module connector, has a hole on either side of the connector.
4. Align the module on the module 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.
5. Attach the mounting rails to the system board by using four screws.
From the underside of the system board, insert screws into the holes in the
board and screw them into the threaded holes in the mounting rail. Do not
tighten until all four screws are in place.
Note -
Use the screws set aside when you removed the standoffs from the
system board.
a. Attach the bottom mounting rail first.
Starting at a corner opposite the connector, insert a screw into the hole in
the board and screw it into the threaded hole in the mounting rail.
Repeat procedure for the second hole in the bottom mounting rail. Do not
tighten.
b. Attach the top mounting rail.
Insert screws into the holes in the board and screw them into the

To install or replace the system board in the enclosure:
Caution -
Use Sun ESD kit P/N 250-1088 (or equivalent) when installing
integrated circuits, printed circuit boards, and drives in a SPARCserver 600MP.
Follow the instructions printed on the ESD mat. See the "Electrostatic
Discharge Precautions" section in Chapter 2 for a description of the ESD mat.
1. Carefully insert the board in the proper slot in the card cage, ensuring
that the board does not slip out of the upper and lower card guides.
The component side of the board must face to the right.
2. Ensure that the extraction levers are in the outward position as you slide
the board toward the backplane connectors.
The board will not seat fully unless the levers are in this starting position.
Caution -
DO NOT FORCE any board into a slot - you may damage it. 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. Use a 2.5 mm Allen wrench to replace the screws that secure the board to
the card cage.
5. Reinstall all cables disconnected in Section 3.2, "Removing the System
Board from the Enclosure."
6. Close the board enclosure.
-
If the system is a 56-inch data cabinet, use a #2 Phillips screwdriver and
replace the two screws that secure the vented rear panel to the enclosure. Go
to step 7.
-
If the system is a 12-slot office pedestal, go to step 7.
-
If the system is a 5-slot office pedestal, replace the top cover:
-
Slide the cover toward the front of the system until the tabs mate with the
retaining slots at the front and rear of the system.
- Secure the top cover by turning the release knob clockwise one quarter
turn or until you hear a click. Go to step 7.
7. Move the system to its normal operating location.
8. Remove and store the wrist strap and Sun ESD mat.
To power-on the system and verify installation:
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.
2. Watch the boot information displayed on the screen to confirm that all
processors are recognized. For example:

Note -
This screen display is an example. The actual message displayed on the
screen will depend on the software running on the system.
The numbers in parenthesis, 4 x 390Z55, indicate the number of processors
running (four), and the revision number of the 600MP dual SuperSPARC
modules that are installed (390Z55).
The cpu 0, cpu 1, cpu 2, and cpu 3 entries indicate the system recognizes
four processors (two dual SuperSPARC modules installed, one in slot 0 and
one in slot 1, with two processors on each dual SuperSPARC module).
If only one dual SuperSPARC module is installed (two processors), the
module must be installed in slot 0, and the system would recognize cpu 0
and cpu 1.
3. Wait for the system to boot. When the login: prompt is displayed, log
in and resume operations.
If you purchased 600MP dual SuperSPARC modules to upgrade your system
and need to return exchanged module(s) to Sun Microsystems, Inc., use the
shipping carton and packing materials set aside when you unpacked the dual
SuperSPARC modules.
Place the exchanged module(s) in the antistatic bag to provide ESD protection.
Fold and tape the end of the bag, and use the foam rubber and/or corrugated
cardboard packing materials to shield the module(s).
To assure proper credit for the exchanged module(s), stick the RMA label that
came with your 600MP dual SuperSPARC modules on the box containing the
module(s) you are returning.
