Notes, Cautions, and Warnings
Warning – The SuperSPARC 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 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.
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.

•Safety precautions
•System boards
•Replacement parts
1.1 Required Tools •Antistatic mat
•Grounding strap
•#1 Phillips screwdriver
•IC extraction tool
1.2 Safety Precautions
Caution – When working on the system board, use an antistatic mat which has
at least 0.25" (6 mm) of cushioning. This cushioning will protect underside
components and prevent harmful board flexing.
Caution – When the system power is turned off, the AC power cord must
remain plugged in to ensure a proper ground.
Protect yourself and the equipment by observing the following precautions.

1.3 System Board Description
Figure 1-1 identifies the major components on the system board.
Table 1-1 Safety Precautions
Item Problem Precaution
Ac power cord ESD (Electrostatic
discharge) The power cord provides a ground path for the cabinet. Do not unplug the cord, even if the power is turned off.
Electric shock Turn the cabinet circuit breaker OFF before opening the cabinet for service.
ESD mat & wrist
or foot strap ESD Use a cushioned, antistatic mat and a grounding strap for these procedures.
System boards ESD Handle a system board by the edges only.Store boards in antistatic bags.
Breakage Parts on a board may break if the board is flexed. Keep the board vertical
when out of the card cage. Place the board on a cushioned mat for service.
Springfingers Personal injury Springfingers have sharp edges, so handle springfinger-equipped screens
and boards carefully.
RFI leakage The screens and panels used on the cabinet suppress radio frequency
interference (RFI) and are required by law in many localities.
Damaged springfingers Replace any screen or board having broken or twisted springfingers with a
new assembly.
Cover panels System damage and
overheating Install all cover panels to keep out foreign objects and prevent overheating.
Filler panels System damage and
overheating Install filler panels in all unused card cage slots. Open slots severely reduce the cooling capability of the system.

Figure 1-1 End and Side Views of the System Board
All system boards are basically the same. No jumper changes are necessary. A
board can be moved to any slot in the card cage for troubleshooting.
However, the system architecture requires that one system board serve as the
system master (being a major part of the bus arbitration system.) Also (in most
cases), the OBP master is found on the system master board.
1.3.1 System Master Board
To determine which board is system master and for a list of system master
requirements, Refer to Section D.1, “System Master Board.”
1.4 Replacement Parts
Table 1-2 lists part numbers for replacements. Replaceable parts are shown
with dotted outlines in Figure 1-2, which shows their relative locations on the
board. These items include SuperSPARC modules, SIMMs, SBus cards, the
OpenBoot PROM and the system board itself.
System error messages may specify non-replaceable components by part name,
but these components cannot be replaced in the field. If any non-replaceable
component fails, replace system board.
