1.3System Precautions
Ensure that the voltage and frequency of the power outlet to be used matches the
electrical rating labels on the equipment.
Wear an ESD wrist/foot strap when handling any magnetic storage devices,
CPU/Memory boards, or other printed circuit boards.
Use only properly grounded power outlets as described in the installation guides.
1-2Sun Fire E6900/E4900 Systems Service Manual • May 2006
Caution – DO NOT make mechanical or electrical modifications to the system or
the cabinet. Sun Microsystems is not responsible for regulatory compliance of
modified cabinets.
Caution – The chassis AC power cord(s) must remain connected to ensure a proper
ground.
1.3.1Captive Screws
Caution – Completely loosen all captive screws before ejecting the System
Controller board, power supplies, and I/O assemblies. Captive screws that have not
been completely loosened may cause damage to the System Controller board, power
supplies, or I/O assemblies.
1.3.2Fan Speed Message
The fan speed message states “WARNING” instead of “NOTICE” when the fan
changes speed. Fans will go from low to high speed if all of the system fans are not
providing cooling, or when the environmental threshold is exceeded for the CPU.
Use the showenv -v command to obtain CPU environmental threshold
information. Refer to the Sun Fire 6800/4810/4800/3800 System Controller CommandReference Manual for correct usage of the showenv command. The system is OK and
is still within the thermal specification when this “WARNING” message appears.
1.3.3Sun Fire Cabinet Fan Tray Power Switches
If the Sun Fire cabinet fan trays are not operating, make sure that the fan trays are
switched on. The fan tray power switches are located in the back of each cabinet fan
tray, below the power cord socket.
Chapter 1 Safety and Tools Requirements1-3
1.3.4Firmware On Replacement Boards and
Assemblies
After installing a board or assembly, use the showboards -p proms command to
determine if the firmware needs to be updated. If an update is required, use either
the system controller flashupdate -f or flashupdate -c command. Refer to

1.5Periodic Maintenance
The Sun Fire system have been designed such that the air intake screens can be
cleaned or changed without the need to power off the system.
The Sun Fire system each have one air intake screen that requires periodic inspection
and cleaning. Inspecting the air intake screen for debris and trapped particles should
be done every three months of operation. The level of debris found on the screen
and surrounding area should be considered in the decision of when to remove and
clean the air intake screen. See Section 12.1 “Cleaning the Air Intake Screen”.
Chapter 1 Safety and Tools Requirements1-5
If the air intake screen collects a substantial amount of debris in less than three
months, investigate the air supply system for sources of contamination and take
corrective action. In addition, notify and update account management, as required.
Have spare air intake screens onsite so that replacements are available when needed
for cleaning.

4.3Redundant Transfer Unit (RTU) and
Redundant Transfer Switch (RTS)
The Sun Fire E6900 system has two RTUs. Each RTU contains two RTS modules. The
primary configuration is the left RTS module with the right RTS module as
secondary for redundancy. The RTUs function as power sequencers.
Each RTS module within an RTU is connected to a separate power source.
Note – If two separate AC power sources (primary and secondary) are not available,
and a single AC power source is used, connect ONLY RTS0 (and RTS2 for Sun Fire
E6900 systems) to the power source. Connecting all RTSs to a single AC power
source (even if separate circuit breakers are used) is not supported and will
adversely affect reliability.
Each RTS module has three LEDs (
The unswitched outlet on each side of the RTU is active only if an RTS is installed on
the same side. If only one RTS is installed, the unswitched outlet on the same side
will have power and the unswitched outlet on the other side will not have power.
These outlets are normally reserved to power the system cabinet fan trays at the top
of the cabinet. If only one RTS is installed then one fan tray must be powered by an
unswitched outlet and the other fan tray by a switched outlet (

If the Sun Fire cabinet fan trays are not operating, make sure that the fan trays are
switched on. The fan tray power switches are located in the back of each cabinet fan
tray, below the power cord socket.
Note – Each RTU has two “unswitched” power outlets (the topmost outlets on each
side of the RTU). By default these unswitched outlets provide power to the fan trays.
If a cabinet has only one RTS installed, then only the associated unswitched outlet
will have power and the remaining fan tray must be connected to one of the
“switched” power outlets.
6.4.2Replacing the Cabinet Fan Trays
1. Ensure that the power switch is set to off (FIGURE 6-5).

■ Refer servicing of equipment to qualified personnel.
7.1Handling Boards and Assemblies
Caution – The chassis AC power cord(s) must remain connected to ensure a proper
ground.
7-1
Caution – The system is sensitive to static electricity. To prevent damage to the
board, connect an antistatic wrist strap or foot strap between you and the system.
Caution – The System Controller board and its modules have surface-mount
components that can be broken if you flex the board.
To minimize the amount of board flexing, observe the following precautions:
■ Hold the board by the edges and by the rear panel, which is attached to the
board.
■ 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.
7.2System Controller Board

7.2.3Resetting the System Controller Board
Caution – For all SC-App versions, resetting a System Controller should be an
absolute last resort, it is always preferable to try the reboot command first. If the
System Controller can not be rebooted, it is safer to take all the domains down
before attempting to reset it.
Note – System Controllers with firmware Versions 5.16.x and later have automatic
System Controller failover implemented for systems with two System Controllers.
The main System Controller puts out a signal which the spare System Controller
monitors. If the spare System Controller does not see this signal, due to a
unresponsive main System Controller, it will automatically initiate a failover and
become the main System Controller This will happen only if failover has been
enabled and is active, otherwise you may risk domain crashes.
Caution – If a System Controller board is still unresponsive to commands after first
attempting to use the reboot command, take all the domains down before attempting
to use the reset switch located on the board itself.
● Press the Reset switch (FIGURE 7-4) by using a pen tip to reset the System
Controller board so that it reboots.
Pressing the reset switch reloads the system controller software.

8.3.2.1DIMM 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.
■ 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 may
be CPU processors without corresponding DIMMs on other boards.
8.3.2.2Removing 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 near the system or in a static-safe bag.

■ 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.
9.1Handling Boards and Assemblies
Caution – The chassis AC power cord must remain connected to ensure a proper
ground.
9-1
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 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 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 re-initialized and
rebooted or dynamically reconfigured into the domain. Refer to the Sun FireMidrange Systems Platform Administration Manual for complete procedures for
initializing a domain. Refer to the Sun Fire Midrange Systems Dynamic ReconfigurationUser Guide for complete DR procedures.

9.2Filler Boards and Filler Panels
To prevent the system from overheating, see Section 1.4, “Filler Boards and Filler
Panels” on page 1-5 for procedures you must follow when removing the I/O
assembly from a powered-on system.
Caution – You must install a filler panel that covers only the front of the assembly
slot, if the system is to be powered up without the I/O assembly installed. Make
sure ALL slots in the I/O assemblies are filled—by cards OR filler boards.
