3.2.3 Replacing DIMMs
The CPU/Memory board has 32 DIMM sockets, which are divided into eight banks
of four DIMMs per bank. Each CPU processor has two corresponding DIMM banks.
It is possible that a CPU processor does not have any DIMMs installed in its
corresponding DIMM bank. However, a populated DIMM bank must have a
corresponding CPU processor installed.
Three types of DIMMs can be used in the DIMM banks:
■ 128 Mbytes
■ 512 Mbytes
■ 1 Gbyte

DIMM in each DIMM bank. The CPU processor number is noted on the metal cover.
3.2.3.1 DIMM Bank Configuration Guidelines
Follow these DIMM configuration guidelines:
■ Each DIMM bank must be fully populated with the same capacity DIMM.
■ Install the larger capacity DIMMs into banks before installing the smaller capacity
DIMMs into banks.
■ The minimum number of DIMMs you can install per CPU processor is four
DIMMs or one bank.
3-12 Sun Fire 6800/4810/4800/3800 Systems Service Manual • Apr il 2001
■ If the number of CPU processors on each CPU/Memory board are the same, place
DIMM banks on CPU/Memory boards that have fewer populated DIMM banks
before placing DIMMs on CPU/Memory boards that already have more
populated DIMM banks.
■ If some CPU/Memory boards have more CPU processors than others, place
DIMMs in DIMM banks on the board with the most CPU processors. There will
be CPU processors without corresponding DIMMs on other boards.
3.2.3.2 Removing DIMMs
Caution – The system is sensitive to static electricity. Make sure you are wearing a
grounded wrist strap when handling system components. Always place components
on a grounded ESD mat close to the system.
1. Remove the applicable CPU/Memory board.
See Section 3.2.2 “Replacing CPU/Memory Boards” on page 3-7.”
2. Place the CPU/Memory board on the ESD mat on a work surface.
3. Locate the slot for the DIMM you need to replace.

3.2.3.3 Installing DIMMs
Install one bank completely on each board before installing the remaining banks on
any board.
Note – All banks must have the same size DIMMs. However, DIMMs from different
manufacturers are interchangeable in a single bank if the DIMMs all have the same
capacity and speed. Sort the DIMMs into banks using the same size DIMMs.
Caution – The system and DIMMs are sensitive to static electricity. To prevent
damage to the DIMMs, make sure you are wearing a grounded wrist strap when
handling them. Always place components on a grounded ESD mat close to the
system.
1. Remove the applicable CPU/Memory board.
See Section 3.2.2 “Replacing CPU/Memory Boards” on page 3-7.”
2. Place the CPU/Memory board on an ESD mat on a work surface.

■ Section 4.2 “Filler Boards and Filler Panels” on page 4-2
■ Section 4.3.3 “Replacing PCI I/O Assemblies” on page 4-7
■ Section 4.3.4 “Replacing PCI Cards” on page 4-9
To protect both yourself and the equipment, make sure you follow the precautions in
Chapter 1. Also observe the following safety precautions when setting up your
equipment:
■ Follow all cautions, warnings, and instructions marked on the equipment.
■ Never push objects of any kind through openings in the equipment, as they may
touch dangerous voltage points or short out components that can result in fire or
electric shock.
■ Refer servicing of equipment to qualified personnel.
4.1 Handling Boards and Assemblies
Caution – The chassis AC power cord must remain connected to ensure a proper
ground.
4-1
Caution – The system is sensitive to static electricity. To prevent damage to the
assembly, connect an antistatic wrist strap between you and the system.
Caution – The PCI I/O assemblies, their modules, and cards have surface-mount
components that can be broken by flexing the assemblies.
To minimize the amount of board flexing, observe the following precautions:
■ Hold the 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 ESD antistatic mat.
■ Do not place the board on a hard surface. Use a cushioned antistatic mat. The
board connectors and components have very thin pins that bend easily.
■ Be careful of small parts located on the component side of the board.
■ 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 – The heat sinks on the board can be damaged by incorrect handling. Do
not touch the heatsinks while replacing or removing the board. Hold the board only
by the edges. If a heatsink is loose or broken, obtain a replacement board.
Caution – The heatsinks on the board can be damaged by improper packaging.
When storing or shipping the board, ensure that the heatsinks have sufficient
protection.
Note – The PCI I/O assembly can be inserted into a powered-on system. The
assembly will not be recognized by the system until the domain has been reinitialized and rebooted. Refer to the Sun Fire 6800/4810/4800/3800 Systems Platform

Repeater Board
To protect both yourself and the equipment, make sure you follow the precautions in
Chapter 1 “Safety and Tools Requirements.”
This chapter explains the following topics:
■ Section 7.1 “Handling Boards and Assemblies” on page 7-1
■ Section 7.2 “Filler Boards” on page 7-2
■ Section 7.3 “Repeater Board” on page 7-2
■ Section 7.3.1 “Replacing Repeater Boards” on page 7-7
For your protection, also observe the following safety precautions when setting up
your equipment:
■ Follow all cautions, warnings, and instructions marked on the equipment.
■ Never push objects of any kind through openings in the equipment, as they may
touch dangerous voltage points or short out components that can result in fire or
electric shock.
■ Refer servicing of equipment to qualified personnel.
7.1 Handling Boards and Assemblies
Caution – The chassis AC power cord must remain connected to ensure a proper
ground.
Caution – The Repeater boards have surface-mount components that can be broken
if you flex the boards.
7-1
To minimize the amount of board flexing, observe the following precautions:
■ Hold the board only by the handle and 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 Sun ESD mat.
■ Do not place the board 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 – The system is sensitive to static electricity. To prevent damage to the unit,
connect an antistatic wrist strap or foot strap between you and the system.
Note – The Repeater board can be inserted into a powered-on system. The board
will not be recognized by the system until the domain has been re-initialized and
rebooted. Refer to the Sun Fire 6800/4810/4800/3800 Systems Platform Administration
Manual for complete procedures for initializing a domain.
7.2 Filler Boards
All empty board slots in the systems must have filler boards installed for cooling
purposes and for EMI protection. To prevent the system from overheating, see
Section 1.4 “Filler Boards and Filler Panels” on page 1-4 for procedures you must
follow when removing Repeater boards from a system.
7.3 Repeater Board
The Repeater board acts as a switch and connects multiple CPU and I/O boards. In
the Sun Fire 4810 and Sun Fire 4800 systems, Repeater boards work as single boards.
However, in the Sun Fire 6800 system, the Repeater boards work in pairs. In the Sun
Fire 3800 system, the equivalent of two Repeater boards is integrated into the active
centerplane.
To remove a Repeater board from the system and install a replacement board, you
must halt the Solaris Operating Environment (either the entire system or only the
affected domains).
