This chapter provides the information you need to remove the system unit
cover, set the clock speed jumpers, and remove and install a SuperSPARC
module on the following systems:
Note -
Variations of the module may be referred to as MBus module, SPARC
module, SuperSPARC module, and SuperSPARC/SuperCache MBus module.
These terms may be used interchangeably in this chapter.
Caution -
Dual module configurations have a module in both the upper and
lower MBus slots, and both modules must be the same. Different modules can
not be installed on the same MLB.
Caution -
See the "Shutting Down the System" section in Chapter 2 to make
sure the system is shut off. The green light-emitting diode (LED) at the front of
the system unit should not be lit.
Caution -
The system chassis power must be turned off and the power cord
must remain plugged in to ensure a proper ground. Do not disconnect the
power cord from the system unit power outlet or the wall socket. This
connection provides the ground path necessary to safely remove and install the
printed circuit boards and components.
Caution -
Make sure that power to your system unit is turned off. The power
cord must remain plugged into the system unit and to the power source to
ensure a proper ground.
1. Use a #2 Phillips screwdriver to fully loosen the captive screw holding the
cover to the back panel.
The screw will remain attached to the back panel after it is fully loosened
from the cover.

wrist strap to the metal casing of the power supply at the rear of the unit top.
Handle boards only by the edges. Do not touch the components themselves or
any metal parts.
Caution -
Do not disconnect the power cord from the system unit power outlet
or from the wall socket. This connection provides the ground path necessary to
safely remove and install the printed circuit boards and components. In
addition, keep the internal power supply cable connected to the MLB.
Caution -
Make sure that the system unit power is turned OFF by checking
that the green LED at the front of the chassis is not lit and the fan in the power
supply is not running.
To remove a SuperSPARC or other MBus module from a system unit:
1. Check that the green LED at the front of the chassis is not lit.
2. Check that the system power cord remains connected to the system and

Dual module configurations using the SMxx SPARC module are not
supported under SunOS 4.x (Solaris 1.x). Dual module configurations require
Solaris 2.1 (or later) or other compatible operating system.
See Table 2-1 on page 2 of Chapter 2 for software requirements specific to your
system.
You must set the system clock speed jumpers on the main logic board to assure
correct operation of the SuperSPARC or other MBus module. The following
sections describe the jumper settings for the two different types of main logic
boards.
4.3.1
Board with Three Jumpers
One type of board has three jumpers: J1401, J1403, and J1404. All three
jumpers must be set as indicated in Figure 4-6 to assure correct operation of the
SuperSPARC module.
4.3.2
Board with One Jumper
The other type of board has one jumper: J1401. This jumper must be set as
indicated in Figure 4-6 to assure correct operation of the SuperSPARC module.
Note -
If the clock speed jumpers are not set correctly, the system may fail to
boot.

reduce the risk of electrical shock, always plug the power cord into a properly
grounded power outlet.
Caution -
Always allow 10 seconds between turning off the power and turning
the power back on. This pause prevents possible damage to power supply
components in your system unit.
Turn the power switches on in this order:
-
External drives (if applicable)
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 -
The screen display is an example only. The actual message displayed on
the screen will depend on the software running on the system.
The numbers in parenthesis, 1 x TMS390Z50, indicate the number of
processors running (one), and the revision number of the SPARC module
that is installed (TMS390Z50).
The mod0 entry indicates the system recognizes one SPARC module that is in
MBus slot 0. If two SPARC modules were installed (two processors), the
system would recognize the two modules - one in MBus slot 0 and one in
MBus slot 1.
3. Wait for the system to boot. When the login: prompt is displayed, log
in and resume operations.
