4.3 Redundant 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 (

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

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. 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.

8.3.2.1 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.

■ 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.

8.3.2.2 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 near the system or in a static-safe bag.

■ Refer servicing of equipment to qualified personnel.

9.1 Handling 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 Fire Midrange Systems Platform Administration Manual for complete procedures for initializing a domain. Refer to the Sun Fire Midrange Systems Dynamic Reconfiguration User Guide for complete DR procedures.
