4.3 Redundant Transfer Unit (RTU) and Redundant Transfer Switch (RTS)

The Sun Fire 6800 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.

Chapter 4 Power 4-17

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 6800 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.

Unswitched outlet (powered)

Circuit breaker

Switched outlets

Each RTS module has three LEDs (

FIGURE 4-15 and TABLE 4-4).

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 (

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(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.

7.2 System Controller Board

The System Controller board contains the system clock and a system controller. One System Controller board is required per system. Two System Controller boards are supported in all systems.

The System Controller board provides:

■ Programmable system and processor clock

■ Serial port

■ RJ-45 Ethernet port

■ Redundant System Controller board that can take over from the main System

Controller board

■ Centralized time-of-day (TOD) chip

■ Centralized reset logic

■ Status and control of power supplies

The System Controller board consists of the following subsystems:

■ Console Bus

■ Clocks

7.2.3 Resetting 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. For System Controllers with firmware 5.11.x or 5.12.x versions, an attempt to reset the board could bring down running domains. 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 5.13.x and later have automatic

System Controller failover implemented for systems with two System Controllers. The main System Controller puts out a clock signal which the spare System Controller monitors. If the spare System Controller does not see a clock signal due to a unresponsive main System Controller, it will automatically initiate a failover and become the main System Controller 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 7-7) by using a pen tip to reset the System

Controller board so that it reboots.

Pressing the reset switch reloads the system controller software.

CHAPTER

CPU/Memory Boards and Components

To protect both yourself and the equipment, make sure you follow the precautions in

Chapter 1.

This chapter contains the following sections:

■ Section 8.1 “Handling Boards and Assemblies” on page 8-1

■ Section 8.2 “Filler Panels and Filler Boards” on page 8-3

■ Section 8.3 “CPU/Memory Boards” on page 8-3

■ Section 8.3.1 “Replacing CPU/Memory Boards” on page 8-7

■ Section 8.3.2 “Replacing DIMMs” on page 8-13

For your protection, also observe the following safety precautions when setting up your equipment:

■ Follow all cautions, warnings, and instructions marked on the equipment.

■ Always use proper ESD equipment and procedures when handling boards and

components.

■ 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.

8.1 Handling Boards and Assemblies

Caution – The chassis AC power cord(s) must remain connected to ensure a proper

ground.

8-1

Caution – The system is sensitive to static electricity. To prevent damage to the

board, connect an antistatic wrist strap between you and the system.

Caution – The CPU/Memory boards have surface-mount components that can be

broken if you flex the boards.

To minimize the amount of board flexing, observe the following precautions:

■ Hold the board only by the handle and 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 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 component parts located on both sides 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 CPU/Memory board is heavy and weighs approximately 17 to 22

pounds (7.7 to 9.0 kg). Take care when removing the board from the system.

Caution – The heatsinks on the board can be damaged by incorrect handling. Do

not touch the heatsinks while replacing or removing the board. 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 CPU/Memory board can be inserted into a powered-on system. The

board will not be recognized by the system until the domain has been dynamically reconfigured to include the board or re-initialized and rebooted. Refer to Sun Fire Midrange Systems Dynamic Reconfiguration User Guide for complete DR procedures or the Sun Fire Midrange Systems Platform Administration Manual for complete procedures for re-initializing a domain.

8.2 Filler Panels and Filler Boards

In order 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 CPU/

Memory boards from a system.

8.3 CPU/Memory Boards

All systems support the following:

■ Up to four CPU processors with each processor supporting two DIMM (dual

inline memory module) banks of four DIMMs per bank

■ Eight Ecache modules (two per CPU processor)

■ Up to 8 Gbytes of memory per CPU processor (CPU/Memory+ board only)

■ Up to 32 DIMMs

On the CPU/Memory board, the memory controller is integrated in the CPU processor. The CPU/Memory board has a metal cover that covers the CPU processors and Ecache.

CPU/Memory board types available are:

■ UltraSPARC® III 750-MHz processor—known as CPU/Memory board

■ UltraSPARC III+ (Cu) 900-MHz processor—known as CPU/Memory+ 900 board

■ UltraSPARC III+ (Cu) 1.05-GHz processor—known as CPU/Memory+ 1.05 board

■ UltraSPARC III+ (Cu) 1.2-GHz processor—known as CPU/Memory+ 1.2 board

There are three LEDs on the CPU/Memory board.
