■ Section 1.9, “Special Tools and Shipping Kit Items” on page 1-13

■ Section 1.10, “System Block Diagrams” on page 1-14

1.1 System Component Hot-Swap Guidelines

In the Sun Fire 15K/12K systems, hot-swapping a component refers to physically removing and replacing a component while the remaining system components are operational.

Note – The System Management Software (SMS) requires 30 seconds to recognize

the removal of a hot-swappable component. The user should wait for a system response before installing a new replacement board.

1-1

The hot-swappable components in the system are listed as follows.

■ System Control board

■ Centerplane support board

■ CPU board

■ MaxCPU board

■ hsPCI assembly

■ System expander board

■ Fan trays

■ Power supplies

■ System control peripheral board

1.2 Configuration Rules

The following rules apply when configuring components of the Sun Fire 15K/12K systems:

■ Every system must be equipped with two centerplane support boards (CSB) in

order to utilize full-width data, address, and response paths. If one CSB fails, there is an interruption in service. However, SMS recovers the domains and the remaining CSB runs in a degraded mode.

■ Every system must be equipped with two System Control (SC) boards.

■ Every system must be equipped with two SC peripheral boards.

■ Every system must be equipped with eight fan trays.

■ Every system must be equipped with six power supplies.

The following rules apply when configuring components on the CPU board:

Note – The CPU/Memory board field-replaceable unit (FRU) is for maintenance use

only. FRUs must not be used to upgrade CPU performance in systems. Usage as such can violate United States export regulations.

The United States government sets limits as to the server configuration exportable to certain destinations or certain customers. Server CPU upgrades must be ordered as standalone CPU upgrade options rather than spares. All upgrades must first be approved by Sun International Trade Services to ensure the system does not exceed

1-2 Sun Fire 15K/12K Systems Service Manual • May 2006

the legal limit for the destination (customer). The following message appears on the label on all CPU FRUs to alert all concerned that this FRU is for maintenance of the system only and should not be used to upgrade a system:

This assembly is for maintenance use only.

Not to be used to upgrade systems.

Use as system upgrades could violate

United States export regulations.

■ All CPU modules must be the same speed.

■ All external cache modules must be the same size.

■ When configuring memory:

■ All sockets within a bank must be fully populated.

■ All DIMM sizes within a bank must be equal.

1.3 Testing the System

The Sun Fire 15K/12K systems use setkeyswitch to diagnose system problems by running hpost(1M) when posting a domain. The hpost(1M) diagnostic probes, configure and test the domain hardware, preparing the system to run OpenBoot™ PROM and subsequently the Solaris operating environment.

The Sun VTS™ diagnostics suite can be used as a verification of a dynamic system domain or an SC. To use the sunvts(1M) command, you must be logged into the host as superuser. Information about sunvts(1M) is located in

/opt/share/man/man1m.

Verify the SMS is up and running by typing:

sc% showfailover -r MAIN

This command explains the role of the SC. The value returned should be MAIN indicating that this SC is providing all resources for the Sun Fire 15K/12K systems. If you do not get this value, consult the SMS Administration Guide.

Chapter 1 Guidelines, Indicators, and Nomenclature 1-3

1.4 Reviewing System Temperatures

The temperature status can be checked at any time by using Sun™ Management Center software or the

Caution – Using the SC CPU reset and SC CPU abort hardware buttons might

corrupt the operating system disk if the operating system has not been properly shut down.

■ SC CPU Reset Button

When the RESET button on the front panel of the SC CPU (CP1500) board is pressed, a Power-on-reset (POR) is generated to the SC CPU board and a peripheral component interconnect (PCI) reset is generated to the PCI devices on the SC main board. This results in a general clearing of the SC CPU board to a power on state, and a reset of the PCI bus on the SC main board.

Using the RESET button will reboot the operating system on the SC if the appropriate OpenBoot PROM (OBP) environment variables have been set.

Chapter 6 System Control (SC) Board 6-3

■ SC CPU Abort Button

When the ABORT button on the front panel of the SC CPU (CP1500) board is pressed, an external initiated reset (XIR) is generated to the CPU module, returning the CPU to a known start-up state. No other devices are affected by this reset.

6.1.2 System Control Board (SC) Replacement Procedures

6.1.2.1 Isolating a Failed System Control Board

1. Check for any error messages during SCPOST.

SCPOST messages are output to an SMS console. To read SC SMS console messages, you must attach a console cable and terminal to the SC.

2. On the SC, check for any error messages in /var/adm/messages and /var/opt/SUNWSMS/adm/platform/messages.

3. Use adb to examine any core files in /var/crash/sc_name.

6.1.2.2 Powering Off a System Control (SC) Board

1. If the System Control board is to be replaced in the spare SC, go to Step 6,as follows. If the System Control board is to be replaced in the main SC, ensure the spare SC is available. Synchronize the main SC to the spare SC by typing:

2. Ensure any board alignment tabs are not bent.

3. Inspect the mating connector before inserting the new board.

Caution – Do not force any board into a slot; it can cause damage to the board and

the system. The board should insert and seat smoothly. If it binds, remove the board and inspect the card cage slot for any obvious obstructions.

4. To install a SC peripheral board, firmly grasp the board by the front handle, supporting the bottom with the other hand, and position it onto the carrier rail.

5. With the insert-eject lever extended, slide the board into the slot until it begins to connect with the centerplane support board connector.

6. Apply firm pressure to the face plate to fully seat the board with the connector.

7. Fold the insert-eject lever inward to fully seat the board ensuring the lever is nested within the front handle.

Failure of the service LED to transition from on to off within 60 seconds after insertion indicates a power-status control fault.

Chapter 7 System Control (SC) Peripheral Board 7-7

7.2.6 Verifying a System Control (SC) Peripheral Board

1. Monitor SCPOST for any error messages during SC boot.

SCPOST messages are output to an SMS console. To read SC SMS console messages, you must attach a console cable and terminal to the SC.

2. Ensure that Solaris software can communicate to all the peripheral devices.

■ For the DVD-ROM, insert a CD and ensure it mounts properly.

■ For hard disks, check that the /dev/dsk and /dev/rdsk entries are correct and

that the Solaris software can access the disks (format, prtvtoc).

■ For the DAT drive, check that the /dev/rmt entries are correct and that the

Solaris software can access the tape device (mt status).

3. Verify the SC Board.
