Preface
This system board manual is written for a trained service provider who intends
to install the SPARCserver 1000™ or SPARCserver 1000E™ system board. In
general, the term SPARCserver 1000 refers to both the SPARCserver 1000 and
the SPARCserver 1000E system board. Where the SPARCserver 1000E is
different, this is explicitly noted.
When You Need Help with UNIX Commands
This manual does not include specific software commands or procedures. In
their place, a software task is named. Refer to the operating system
documentation that was shipped with your system when you need help with
commands or procedures such as:
•Shutting down the system
•Booting the system
•Configuring devices
•Other software procedures
Depending on the operating system you are using, complete descriptions of
commands and procedures can be found in:
•On-line AnswerBook™ documentation that comes with Solaris
•Other software documentation you received with your system

Notes, Cautions, and Warnings
Warning – The SPARC module has a hot surface. Avoid contact. Surfaces are hot
and may cause personal injury if touched.
Warning – This equipment contains lethal voltage. Accidental contact can
result in serious injury or death.
Caution – Improper handling by unqualified personnel can cause serious
damage to this equipment. Unqualified personnel who tamper with this
equipment may be held liable for any resultant damage to the equipment.
Individuals who remove any outer panels to access this equipment must
observe all safety precautions and ensure compliance with skill level
requirements, certification, and all applicable local and national laws.
Procedures contained in this document must be performed by qualified
service-trained maintenance providers.
Note – Before you begin, carefully read each of the procedures in this manual.
If you have not performed similar operations on comparable equipment, do
not attempt to perform these procedures.

1.2 Safety Precautions
To protect yourself and the equipment, observe the following precautions
when working on or in the server.
Table 1-1 Safety Precautions
Item Problem Precaution
AC cord ESD (Electrostatic
discharge) Ensure the AC cord connects the server to a grounded electrical outlet. The power cord provides a ground path for the unit to bleed off electrostatic voltage.
Wrist strap or
Foot strap ESD Wear a conductive wrist strap or foot strap when you handle printed circuit boards. Proper use of a conductive strap reduces the risk of damage to the
boards by discharging static electricity to ground.
ESD mat ESD The mat provides ESD protection when used with a wrist strap or foot strap.
The mat also cushions the board to prevent breakage of any small parts that
contact the bench surface.
PC boards ESD Handle the PC board by the edges only. Store the board in an antistatic bag.
Cover panels System damage
and overheating Install all cover panels after performing any service work on the system. The panels keep out foreign objects to prevent physical damage to internal parts and
guide airflow to prevent overheating.
Airflow
restrictor boards
(filler panels)
System damage
and overheating Install airflow restrictor boards in all unused card cage slots. Unused, open slots severely reduce the cooling capability of the system and can lead to equipment
damage from overheating.

1.3 System Board Description
Figure 1-1 shows the locations of major components on the system board.
Figure 1-1 End and Side Views of the System Board
All system boards are essentially the same; no jumper changes are necessary.
System boards can be moved to any slot, especially during troubleshooting.
However, the system board in card cage slot 0 is considered the system bus
master. The minimum configuration for this board requires a SPARC® module
in location A. If a serial-interface console is used, it must be plugged into
RS232 connector A on the system master. If a color monitor is used, a color-
graphics interface card must be installed in SBus slot 1 on the system master.
Also, by convention, system boards are installed in the lowest card cage slot
numbers first. Fill all SuperSPARC module A slots before using the B slots. Fill
all group 0 SIMMs before installing any group 1 SIMMs.
For comprehensive slot assignment rules and configuration priorities, refer to
Appendix C, “General Rules for System Configuration.”

1.4 System Board Block Diagram
Figure 1-2 is a block diagram of the system board. The SuperSPARC modules,
SIMMs, and optional SBus cards are removable and can be replaced or moved
to another SPARCserver 1000 system board.

The components shown in solid outlines cannot be replaced in the field; if the
diagnostic self-tests report that a non-removable component failed, the entire
system board must be replaced.
