2 Sun Fire V480 Server Parts Installation and Removal Guide • December 2002

Front Panel LEDs

Several front panel LEDs provide general system status, alert you to system problems, and help you to determine the location of system faults.

During system startup, LEDs are individually toggled on and off to verify that each one is working correctly. Other LEDs located on the front of the system work in conjunction with specific fault LED icons. For example, a fault in the disk subsystem illuminates the disk drive Fault LED next to the affected disk drive. Since all front panel status LEDs are powered by the system’s 5-volt standby power source, fault LEDs remain lit for any fault condition that results in a system shutdown.

System Status LEDs

At the top left of the system as you look at its front are three system status LEDs. The Power/OK LED and the system Fault LED provide a snapshot of the overall system status. The Locator LED helps you to quickly locate a specific system even though it may be one of dozens or even scores of systems in a room. The Locator LED is at the far left in the cluster, and is lit by command from the administrator.

System status LEDs

Each system status LED has a corresponding LED on the back panel.

Chapter 1 Identifying Front and Back Panel Features 3

Listed from left to right, the system status LEDs operate as described in the following table.

TABLE1-1 System Status LEDs

Icon Name Description

Locator This white LED is lit by Solaris command or by Remote

System Control (RSC) and Sun Management Center (Sun MC) commands to help locate the system. See the Sun Fire V480 Server Administration Guide for information about turning on the Locator LED.

Fault This amber LED lights steadily when a system fault is

detected. For example, the system Fault LED lights when a fault occurs in a power supply, disk drive, or cooling fan.

In addition to the system Fault LED, other fault LEDs may also be lit, depending on the nature of the fault. If the system Fault LED is lit, check the status of other fault LEDs on the front panel to determine the nature of the fault.

During the boot process, this LED flashes for approximately three seconds. If you press the Power button twice within the three seconds, the system will come up with factory-set Safe mode IDPROM variable settings, returning the system to the

ok firmware prompt. See your Sun Fire V480 Server Administration Guide for more information.

See your Sun Fire V480 Server Administration Guide for information about troubleshooting your server.

Power/OK This green LED lights continuously when the system power is

on.

Power Button

The system Power button is recessed to prevent accidentally turning the system on or off. The ability of the Power button to turn the system on or off is controlled by the system control switch.

If the operating system is running, pressing and releasing the Power button initiates a graceful software system shutdown. Pressing and holding in the Power button for five seconds causes an immediate hardware shutdown.

Caution – Whenever possible, you should use the graceful shutdown method.

Forcing an immediate hardware shutdown may cause disk drive corruption and loss of data.

System Control Switch

The four-position system control switch on the system’s status and control panel controls the power-on modes of the system and prevents unauthorized users from powering off the system or reprogramming system firmware. In the following illustration, the system control switch is in the Locked position.

System control switch

Power button

8 Sun Fire V480 Server Parts Installation and Removal Guide • December 2002

The following table describes the function of each system control switch setting.

TABLE1-5 System Control Switch Settings

Icon Position Description

Normal This setting enables the system Power button to power the

system on or off.

Locked This setting disables the system Power button to prevent

unauthorized users from powering the system on or off. It also disables the keyboard Stop-A command, terminal Break key command, and ~# tip window command, preventing users from suspending system operation to access the system ok prompt.

The Locked setting, used for normal day-to-day operations, also prevents unauthorized programming of the system Boot PROM.

Diagnostics This setting forces the power-on self-test (POST) and

OpenBoot and system resets. The Power button functions the same as when the system control switch is in the Normal position.

Forced Off This setting forces the system to power off immediately and to

enter 5-volt standby mode. It also disables the system Power button. You may want to use this setting when AC power is interrupted and you do not want the system to restart automatically when power is restored. With the system control switch in any other position, if the system were running prior to losing power, it restarts automatically once power is restored.

™ Diagnostics tests to run during system startup

The Forced Off setting also prevents an RSC console from restarting the system. However, the RSC card continues to operate using the system’s 5-volt standby power.

How to Power Off the System

Before You Begin

Applications running on the Solaris operating environment can be adversely affected by a poorly executed system shutdown. Make sure you have gracefully shut down any applications before powering off the system.

What to Do

1. Notify users that the system will be powered down.

2. Back up the system files and data, if necessary.

3. Ensure that the system control switch is in the Normal or Diagnostics position.

4. Press and release the Power button on the system front panel.

The system begins a graceful software system shutdown.

Note – Pressing and releasing the Power button initiates a graceful software system

shutdown. Pressing and holding in the Power button for five seconds causes an immediate hardware shutdown. Whenever possible, you should use the graceful shutdown method. Forcing an immediate hardware shutdown may cause disk drive corruption and loss of data. Use that method only as a last resort.

5. Wait for the system Power/OK LED to turn off.

6. Turn the system control switch to the Forced Off position.

Caution – Be sure to turn the system control switch to the Forced Off position

before handling any internal components. Otherwise, it is possible for an operator at a Remote System Control (RSC) console to restart the system while you are working inside it. The Forced Off position is the only system control switch position that prevents an RSC console from restarting the system.

7. Remove the system key from the system control switch and keep it in a secure place.

22 Sun Fire V480 Server Parts Installation and Removal Guide • December 2002

What Next

Continue with your parts removal and installation, as needed.

How to Initiate a Reconfiguration Boot

After installing any new internal option or external storage device, you must perform a reconfiguration boot so that the operating system is able to recognize the newly installed device(s). In addition, if you remove any device and do not install a replacement device prior to rebooting the system, you must perform a reconfiguration boot in order for the operating system to recognize the configuration change. This requirement also applies to any component that is connected to the system’s I supplies.

This requirement does not apply to any component that is:

■ Installed or removed as part of a hot-plug or hot-swap operation

■ Installed or removed before the operating system is installed

■ Installed as an identical replacement for a component that is already recognized

by the operating system

C bus, including memory modules, CPU/Memory boards, and power

Before You Begin

Caution – Before you power on the system, make sure that the system doors and all

panels are properly installed.

You need a system ASCII terminal, local graphics terminal, or a tip connection to the Sun Fire V480 server in order to issue software commands. See your Sun Fire V480 Server Administration Guide.

What to Do

1. Turn on power to any peripherals and external storage devices.

Read the documentation supplied with the device for specific instructions.

2. Turn on power to the ASCII terminal or local graphics terminal.

Chapter 2 Preparing to Service the System 23

3. Insert the system key into the system control switch and turn the system control switch to the Diagnostics position.

Use the Diagnostics position to run POST and OpenBoot Diagnostics tests to verify that the system functions correctly with the new part(s) you just installed. See “Locating Front Panel Features” on page 2 for information about system control switch settings.

4. Press the Power button below the system control switch to power on the system.

5. When the system banner is displayed on the system console, immediately abort the boot process to access the system ok prompt.

The system banner contains the Ethernet address and host ID. To abort the boot process, use one of the following methods:

■ Hold down the Stop key and press A on a Sun keyboard.

■ Press the Break key on the terminal keyboard.

■ Type ~# in a tip window.

Note – The system may take anywhere from 30 seconds to two minutes before the

system banner appears. This time depends on the system configuration (number of CPUs, memory modules, PCI cards) and the level of power-on self-test (POST) and OpenBoot Diagnostics tests being performed.

6. At the ok prompt, type:

ok env-on Environmental monitor is ON ok boot -r

The env-on command reenables the OpenBoot environmental monitor, which may have been disabled as a result of the abort key sequence. Booting the system with the boot -r command rebuilds the device tree for the system, incorporating any newly installed options so that the operating system will recognize them.

7. Turn the system control switch to the Locked position, remove the key, and keep it in a secure place.

This prevents anyone from accidentally powering off the system.

What Next

The system’s front panel LED indicators provide power-on status information. For more information about the system LEDs, see:

When you restart the system, be sure to run power-on self-test (POST) and OpenBoot Diagnostics tests to verify that the system functions correctly with the new parts you installed. You do not have to perform a reconfiguration boot with FCAL drives. For additional information, see your Sun Fire V480 Server Administration Guide.

How to Remove a Disk Drive Using the Hot-Plug Operation

The system’s disk hot-plug feature enables you to remove a disk drive without shutting down the operating system or turning off the system power. The way in which you remove a disk drive depends on the application you are using and if you are replacing a drive, adding a new one, or removing a drive permanently.

When you remove a drive using the hot-plug operation, you need to stop the disk drive and take it offline to remove the logical software links to the disk drive, and to reconfigure the file systems so that they now ignore the removed drive. You may also have to reconfigure your application software to operate without the removed drive.

Use the luxadm software tool to remove a Sun Fire V480 server’s internal disk drive using the hot-plug operation. The following procedure describes the general steps involved, but your specific device names may be different.

Caution – Do not hot-plug drives without the correct preparations. The system

supports hot-plugging disk drives, but there are software procedures that you must perform before you remove or install any drive.

Chapter 3 Servicing the Front Panel Components 57

Before You Begin

If a disk drive fails, the system Fault LED and the disk drive Fault LED will light. In the following figure, the Disk Drive 1 Fault LED is lit.

If you have not configured the system with two boot disks, you cannot hot-plug a single boot disk. You can only hot-plug the boot disk if you have configured a twodisk mirror of the boot disk for hot-plugging. If the system is configured with a boot disk and a data disk, you can hot-plug the data disk, but not the boot disk.

Complete these tasks:

■ Obtain the logical device name(s) for the device(s) you plan to remove. See your

Sun Fire V480 Server Administration Guide for more information.

■ Select the disk and stop any activity or applications accessing the disk drive.

■ Unmount any file systems mounted on the disk drive.

You must follow antistatic precautions when handling a disk drive. Complete this task:

About Memory Modules

The Sun Fire V480 server uses 3.3V, high-capacity dual inline memory modules (DIMMs). The DIMMs are built with synchronous dynamic random access memory (SDRAM) chips that operate at a 75-MHz clock frequency. The system supports DIMMs with the following capacities:

■ 256 Mbytes

■ 512 Mbytes

■ 1 Gbyte

Support for larger capacity DIMMs may be offered as they become available. Each CPU/Memory board contains slots for 16 DIMMs. Total system memory ranges

from a minimum of 2 Gbytes (one CPU/Memory board with eight 256-Mbyte DIMMs) to a maximum of 32 Gbytes (two CPU/Memory boards fully populated with 1-Gbyte DIMMs).

Within each CPU/Memory board, the 16 DIMM slots are organized into groups of four. The system reads from, or writes to, all four DIMMs in a group simultaneously. DIMMs, therefore, must be added in sets of four.

The figure below shows the DIMM slots and DIMM groups on a CPU/Memory board. Every fourth slot belongs to the same DIMM group. The four groups are designated A0, A1, B0, and B1.

Chapter 4 Servicing the CPU/Memory Board and Related Components 79

Follow these configuration rules when installing memory:

■ DIMMs must be added four at a time within the same group of DIMM slots;

every fourth slot belongs to the same DIMM group.

■ Each group used must have four identical capacity DIMMs installed (for example,

four 256-Mbyte DIMMs, four 512-Mbyte DIMMs, or four 1-Gbyte DIMMs).

■ Each CPU/Memory board must be populated with a minimum of eight DIMMs,

with at least one A group populated (A0 or A1) and at least one B group populated (B0 or B1).
