For more information about system memory, see “DIMMs” on page 68.
External Ports
The Sun Fire V445 server provides four Gigabit Ethernet ports, one 10BASE-T network management port, two Serial ports, and four USB ports.
Gigabit Ethernet Ports
The four on-board Gigabit Ethernet ports located on the back panel support several modes of operations at 10, 100, and 1000 megabits per second (Mbps). Additional Ethernet interfaces or connections to other network types can be provided by installing the appropriate PCI interface cards. Multiple network interfaces can be combined with Solaris Internet Protocol (IP) network multipathing software to
Chapter 1 System Overview 3
Page 30
provide hardware redundancy and failover capability, as well as load balancing on outbound traffic. Should one of the interfaces fail, the software can automatically switch all network traffic to an alternate interface to maintain network availability. For more information about network connections, see “Configuring the Primary
Network Interface” on page 132 and “Configuring Additional Network Interfaces” on page 133.
10BASE-T Network Management Port
The network management port (labeled NET MGT) is located on the chassis back panel. This port is reserved for use with the ALOM system controller and the system console.
This port provides direct network access to the ALOM system controller card and its firmware. This port also provides access to the system console, power-on self-test (POST) output messages, and ALOM system controller messages. Use this port to perform remote administration, including externally initiated resets (XIR).
Serial Management and DB-9 Ports
The DB-9 port is POSIX compliant with a general-purpose DB-9 connector (labeled TTYB) on the system back panel. The serial management port is an RJ-45 connector (labeled SERIAL MGT) on the chassis back panel, and is reserved for use with the ALOM system controller and the system console.
The serial management port enables you to set up a system console device, without configuring an existing port. All power-on self-test (POST) and ALOM system controller messages are directed to the serial management port by default. For more information, see “About the Serial Ports” on page 90.
USB Ports
The front and back panels both provide two Universal Serial Bus (USB) ports for connecting peripheral devices such as modems, printers, scanners, digital cameras, or a Sun Type-6 USB keyboard and mouse. The USB ports are USB 2.0 compliant, and support 480Mbps, 12Mbps, and 1.5Mbps speeds. For additional details, see
“About the USB Ports” on page 89.

Page 31
RAID 0,1 Internal Hard Drives
Internal disk storage is provided by up to eight 2.5 inch (5.1 cm) high, hot-pluggable, SAS disk drives. The basic system includes a SAS disk backplane that accommodates eight disks capable of data transfer rates of up to 320 megabytes per second. See
“About the Internal Disk Drives” on page 81 and “Locating Back Panel Features” on page 15.
External multidisk storage subsystems and redundant array of independent disks (RAID) storage arrays can be supported by installing peripheral component interconnect (PCI) host adapter cards along with the appropriate system software. Software drivers supporting SCSI and other types of devices are included in the Solaris OS. In addition, the system supports internal hardware mirroring (RAID 0,1) using the on-board SAS controller. See “About RAID Technology” on page 114.
PCI Subsystem
System I/O is handled by two expanded Peripheral Component Interconnect (PCI) ­Express buses and two PCI-X buses. The system has eight PCI slots: four 8 lane PCI­Express slots (two of which also support 16 lane form factor cards) and four PCI-X slots. The PCI-X slots operate at up to 133MHz, are 64-bit capable, and support legacy PCI devices. All PCI-X slots comply with PCI Local Bus Specification Rev 2.2 and PCI-X Local Bus Specification Rev 1.0. All PCIe Slots comply with PCI-Express Base Specification r1.0a and PCI Standard SHPC Specification, r1.1. For additional details, see “About the PCI Cards and Buses” on page 75.
Power Supplies
The basic system includes four 550-watt power supplies, each with its own cooling fan. The power supplies are plugged into a separate power distribution board (PDB). This board is connected to the motherboard through 12 volt high current bus bars. Two power supplies provide sufficient current (1100 DC watts) for maximum configuration. The other power supplies provide 2+2 redundancy, enabling the system to continue operating if up to two power supplies fail.
The power supplies are hot-swappable – you can remove and replace a faulty power supply without shutting down the system. With four separate AC inlets you can wire the server with a fully redundant AC circuit. A failed power supply does not need to remain installed to sustain proper cooling. For more information about the power supplies, see “About the Power Supplies” on page 83.
Chapter 1 System Overview 5
Page 32
System Fan Trays
The system is equipped with six fan trays organized into three redundant pairs. One redundant pair is for cooling the disk drives. The other two redundant pairs are for cooling the CPU/memory modules, memory DIMMs, I/O subsystem, and provide front-to-rear cooling of the system. Not all fans must be present to provide adequate cooling – only one fan per redundant pair must be present.
Note – All system cooling is provided by the fan trays – power supply fans do not
provide system cooling.
See “About the System Fan Trays” on page 86 for details.
ALOM System Controller Card
The Sun ALOM system controller card enables system management and administration for the Sun Fire V445 server over a serial line or an Ethernet network. ALOM system controller provides remote system administration for geographically distributed or physically inaccessible systems. These features include powering on/off the system and enabling diagnostics. The firmware installed on the ALOM system controller card enables you to monitor the system, without having to install any supporting software.
The ALOM system controller card runs independently of the host system, and operates off of standby power from the systems power supplies. This allows the ALOM system controller to serve as a lights out management tool that continues to function even when the server operating system goes offline or when the server is powered off.
Hardware Disk Mirroring
The SAS controller supports hardware disk mirroring (RAID 0,1) capabilities for all internal disk drives, resulting in improved disk drive performance, data integrity, data availability, and fault recovery.
Predictive Self-Healing
Sun Fire V445 servers with Solaris 10 or later feature the latest fault management technologies. With Solaris 10, Sun introduces a new architecture for building and deploying systems and services capable of predictive self-healing. Self-healing
6 Sun Fire V445 Server Administration Guide • August 2006
Page 33
technology enables Sun systems to accurately predict component failures and mitigate many serious problems before they actually occur. This technology is incorporated into both the hardware and software of the Sun Fire V445 server.
At the heart of the Predictive Self-Healing capabilities is the Solaris Fault Manager, a service that receives data relating to hardware and software errors, and automatically and silently diagnoses the underlying problem. Once a problem is diagnosed, a set of agents automatically responds by logging the event, and if necessary, takes the faulty component offline. By automatically diagnosing problems, business-critical applications and essential system services can continue uninterrupted in the event of software failures, or major hardware component failures.
New Features
The Sun Fire V445 server provides faster computing in a denser, more power­efficient package. The following key new features are included:
■ UltraSPARC IIIi CPU
The UltraSPARC IIIi CPU provides a faster JBus system interface bus that considerably enhances system performance.
■ Higher I/O Performance With Fire ASIC, PCI-Express, and PCI-X
The Sun Fire V445 server provides higher I/O performance with PCI-Express cards integrated with the latest Fire chip (NorthBridge). This integration allows higher bandwidth and lower latency datapaths between the I/O subsystem and the CPUs. The server supports two full height or low profile/full depth 16 lane (wired 8 lane) PCI-Express cards and two full height or low profile/half depth 8 lane PCI-Express cards. The system also supports four PCI-X slots that operate at up to 133MHz, are 64-bit capable, and support legacy PCI cards.
The Fire ASIC is a high performance JBus to PCI-Express host bridge. On the host bus side, Fire supports a coherent, split transaction, 128-bit JBus interface. On the I/O side, Fire supports two 8 lane serial PCI-Express interconnects.
■ SAS Disk Subsystem
Compact 2.5-inch disk drives provide faster, denser, more flexible, and more robust storage. Hardware RAID 0/1 is supported across all eight disks.
■ ALOM Control of System Settings
The Sun Fire V445 server provides robust remote access to system functions and the system controller. The physical system contol keyswitch has been removed and the switch settings (power on/off, diagnostic mode) are now emulated with ALOM and software commands.
Chapter 1 System Overview 7
Page 34
Other new features include the following:

Page 35
For information about front panel controls and indicators, see “Front Panel
Indicators” on page 9.
The system is configured with up to eight disk drives, which are accessible from the front of the system.
Front Panel Indicators
Several front panel indicators provide general system status, alert you to system problems, and help you to determine the location of system faults.
During system startup, the indicators are toggled on and off to verify that each one is working correctly. Indicators located on the front panel work in conjunction with specific fault indicators. For example, a fault in the power supply subsystem illuminates the power supply Service Required indicator on the affected power supply, as well as the system Service Required indicator. Since all front panel status indicators are powered by the system’s standby power source, fault indicators remain lit for any fault condition that results in a system shutdown.
At the top left of the system as you look at its front are six system status indicators. Power/OK indicator and the Service Required indicator provide a snapshot of the overall system status. The Locator indicator helps you to quickly locate a specific system even though it may be one of numerous systems in a room. The Locator indicator/button is at the far left in the cluster, and is lit remotely by the system administrator, or toggled on and off locally by pressing the button.
FIGURE 1-2 Front Panel System Status Indicators
Each system status indicator has a corresponding indicator on the back panel.

Sun Cluster Software
Sun Cluster software enables you to connect up to eight Sun servers in a cluster configuration. A cluster is a group of nodes that are interconnected to work as a single, highly available and scalable system. A node is a single instance of Solaris software. The software can be running on a standalone server or on a domain within a standalone server. With Sun Cluster software, you can add or remove nodes while online, and mix and match servers to meet your specific needs.
Sun Cluster software delivers high availability through automatic fault detection and recovery, and scalability, ensuring that mission-critical applications and services are always available when needed.
Chapter 1 System Overview 21
Page 48
With Sun Cluster software installed, other nodes in the cluster will automatically take over and assume the workload when a node goes down. The software delivers predictability and fast recovery capabilities through features such as local application restart, individual application failover, and local network adapter failover. Sun Cluster software significantly reduces downtime and increases productivity by helping to ensure continuous service to all users.
The software lets you run both standard and parallel applications on the same cluster. It supports the dynamic addition or removal of nodes, and enables Sun servers and storage products to be clustered together in a variety of configurations. Existing resources are used more efficiently, resulting in additional cost savings.
Sun Cluster software allows nodes to be separated by up to 10 kilometers. This way, in the event of a disaster in one location, all mission-critical data and services remain available from the other unaffected locations.
For more information, see the documentation supplied with the Sun Cluster software.
Sun Management Center Software
Sun Management Center software is an open, extensible system monitoring and management tool. The software is written in Java and uses Simple Network Management Protocol (SNMP) to provide enterprise-wide monitoring of Sun servers and workstations, including their subsystems, components, and peripheral devices.
For more information, see “About Sun Management Center” on page 204.

About Communicating With the System
To install your system software or to diagnose problems, you need some way to interact at a low level with the system. The system console is Sun’s facility for doing this. You use the system console to view messages and issue commands. There can be only one system console per computer.
The serial management port (SERIAL MGT) is the default port for accessing the system console upon initial system installation. After installation, you can configure the system console to accept input from and send output to different devices. See
TABLE 2-1 for a summary.

Using the System Console
The system console device can be either a standard alphanumeric terminal, terminal server, Tip connection from another Sun system, or a local graphics monitor. The default connection is through the serial management port (labeled SERIAL MGT) on the chassis back panel. You can also connect an alphanumeric terminal to the serial (DB-9) connector (as TTYB) on the system back panel. A local graphics monitor requires installation of a PCI graphics card, monitor, USB keyboard, and mouse. You can also access the system console through a network connection with the network management port.
The system console displays status and error messages generated by firmware-based tests during system startup. After those tests have been run, you can enter special commands that affect the firmware and alter system behavior. For more information about tests that run during the boot process, see Chapter 8 and Chapter 9.
Once the OS is booted, the system console displays UNIX system messages and accepts UNIX commands.
Chapter 2 Configuring the System Console 25
Page 52
To use the system console, you need some means of getting data in to and out of the system, which means attaching some kind of hardware to the system. Initially, you might have to configure that hardware, and load and configure appropriate software as well.
You also must ensure that the system console is directed to the appropriate port on the Sun Fire V445 server’s back panel – generally, the one to which your hardware console device is attached. (See
FIGURE 2-1.) You do this by setting the input-
device and output-device OpenBoot configuration variables.

On Sun Fire V445 servers, the system console comes preconfigured to allow input and output only by means of hardware devices connected to the serial or network management ports. However, because the network management port is not available until network parameters are assigned, your first connection must be to the serial management port. The network can be configured once the system is connected to power and ALOM completes its self test.
Chapter 2 Configuring the System Console 27
Page 54
Typically, you connect one of the following hardware devices to the serial management port:
■ Terminal server
■ Alphanumeric terminal or similar device
■ A Tip line connected to another Sun computer
This provides for secure access at the installation site.
Network management port Serial management port (NET MGT) (SER MGT)
FIGURE 2-2 Serial Management Port (Default Console Connection)
Using a Tip line might be preferable to connecting an alphanumeric terminal, since the tip command allows you to use windowing and OS features on the machine being used to connect to the Sun Fire V445 server.
Although the Solaris OS sees the serial management port as TTYA, the serial management port is not a general-purpose serial port. If you want to use a general­purpose serial port with your server – to connect a serial printer, for instance – use the regular 9-pin serial port on the back panel of the Sun Fire V445. The Solaris OS sees this port as TTYB.
For instructions on accessing the system console through a terminal server, see
“Accessing the System Console With a Terminal Server” on page 42.
For instructions on accessing the system console through an alphanumeric terminal, see “Accessing the System Console With an Alphanumeric Terminal” on page 51.

Access Through the Network Management Port
Once you have configured the network management port, you can connect an Ethernet-capable device to the system console through your network. This connection provides for remote monitoring and control. In addition, up to four simultaneous connections to the system controller sc> prompt are available through the network management port. For more information, see “Activating the Network
Management Port” on page 40.
For more information about the system console and the ALOM system controller, see:
■ “About the sc> Prompt” on page 31
■ “About the ok Prompt” on page 33
ALOM
ALOM software is preinstalled on the server’s system controller (SC) and is enabled at the first power on. ALOM provides remote powering on and off, diagnostics capabilities, environmental control, and monitoring operations for the server. The primary functions of ALOM include the following:
■ Operation of system indicators
■ Fan speed monitoring and adjustment
■ Temperature monitoring and alerts
■ Power supply health monitoring and control
■ USB overcurrent monitoring and alerts
■ Hot-plug configuration change monitoring and alerts
■ Dynamic FRU ID data transactions
For more information about ALOM software, see “About the ALOM System
Controller Card” on page 71.
Alternative System Console Configuration
In the default configuration, system controller alerts and system console output appear interspersed in the same window. After initial system installation, you can redirect the system console to take its input from and send its output to the serial port TTYB, or to a graphics card’s port.
A serial port and the PCI slots are located on the rear panel. Two USB ports are located on the front panel.
The chief advantage of redirecting the system console to another port is that it allows you to divide system controller alerts and system console output into two separate windows.
Chapter 2 Configuring the System Console 29
Page 56
However, there are some serious disadvantages to alternative console configuration:
■ POST output can only be directed to the serial management and network
management ports. It cannot be directed to TTYB or to a graphics card’s port.
■ If you have directed the system console to TTYB, you cannot use this port for any
other serial device.
■ In a default configuration, the serial management and network management ports
enable you to open up to four additional windows by which you can view, but not affect, system console activity. You cannot open these windows if the system console is redirected to TTYB or to a graphics card’s port.
■ In a default configuration, the serial management and network management ports
enable you to switch between viewing system console and system controller output on the same device by typing a simple escape sequence or command. The escape sequence and commands do not work if the system console is redirected to TTYB or to a graphics card’s port.
■ The system controller keeps a log of console messages, but some messages are not
logged if the system console is redirected to TTYB or to a graphic card’s port. The omitted information could be important if you need to contact Sun customer service with a problem.
For all the preceding reasons, the best practice is to leave the system console in its default configuration.
You change the system console configuration by setting OpenBoot configuration variables. See “Reference for System Console OpenBoot Configuration Variable
Settings” on page 56.
You can also set OpenBoot configuration variables using the ALOM system controller. For details, see the Sun Advanced Lights Out Manager (ALOM) Online Help.
Accessing the System Console Through a Graphics Monitor
The Sun Fire V445 server is shipped without a mouse, keyboard, monitor, or frame buffer for the display of bitmapped graphics. To install a graphics monitor on the server, you must install a frame buffer card into a PCI slot, and attach a monitor, mouse, and keyboard to the appropriate back panel ports.
After starting the system, you might need to install the correct software driver for the PCI card you have installed. For detailed hardware instructions, see “To Access
the System Console With a Local Graphics Monitor” on page 54.
Note – Power-on self-test (POST) diagnostics cannot display status and error
messages to a local graphics monitor.
30 Sun Fire V445 Server Administration Guide • August 2006
Page 57
About the sc> Prompt
The ALOM system controller runs independently of the Sun Fire V445 server and regardless of system power state. When you connect a Sun Fire V445 server to AC power, the ALOM system controller immediately starts up, and begins monitoring the system.
Note – To view ALOM system controller boot messages, you must connect an
alphanumeric terminal to the serial management port before connecting the AC power cords to the Sun Fire V445 server.
You can log in to the ALOM system controller at any time, regardless of system power state, as long as AC power is connected to the system and you have a way of interacting with the system. You can also access the ALOM system controller prompt (sc>) from the ok prompt or from the Solaris prompt, provided the system console is configured to be accessible through the serial management and network management ports. For more information, see the following:
■ “Entering the ok Prompt” on page 38
■ “About Switching Between the ALOM System Controller and the System
Console” on page 36
The sc> prompt indicates that you are interacting with the ALOM system controller directly. It is the first prompt you see when you log in to the system through the serial management port or network management port, regardless of system power state.
Note – When you access the ALOM system controller for the first time, it forces you
to create a user name and password for subsequent access. After this initial configuration, you will be prompted to enter a user name and password every time you access the ALOM system controller.
Chapter 2 Configuring the System Console 31
Page 58
Access Through Multiple Controller Sessions
Up to five ALOM system controller sessions can be active concurrently, one session through the serial management port and up to four sessions through the network management port.
Users of each of these sessions can issue commands at the sc> prompt, but only one user session can have write-access the the system console at anytime. The other sessions accessing the system console will have read-only capability.
For more information, see:
■ “Using the Serial Management Port” on page 39
■ “Activating the Network Management Port” on page 40.)
Any additional ALOM system controller sessions afford passive views of system console activity, until the active user of the system console logs out. However, the console -f command, if you enable it, allows users to seize access to the system console from one another. For more information, see the Sun Advanced Lights Out Manager (ALOM) Online Help.
Ways of Reaching the sc> Prompt
There are several ways to get to the sc> prompt. These are:
■ If the system console is directed to the serial management and network
management ports, you can type the ALOM system controller escape sequence (#.).
Note – #. (pound period) is the default setting for the escape sequence to enter
ALOM. It is a configurable variable.
■ You can log in directly to the ALOM system controller from a device connected to
the serial management port. See “Using the Serial Management Port” on page 39.
■ You can log in directly to the ALOM system controller using a connection through
the network management port. See “Activating the Network Management Port”
on page 40.

About the ok Prompt
A Sun Fire V445 server with the Solaris OS installed is capable of operating at different run levels. A synopsis of run levels follows. For a full description, see the Solaris system administration documentation.
Most of the time, you operate a Sun Fire V445 server at run level 2 or run level 3, which are multiuser states with access to full system and network resources. Occasionally, you might operate the system at run level 1, which is a single-user administrative state. However, the lowest operational state is run level 0. At this state, it is safe to turn off power to the system.
When a Sun Fire V445 server is at run level 0, the ok prompt appears. This prompt indicates that the OpenBoot firmware is in control of the system.
There are a number of scenarios in which OpenBoot firmware control can happen.
■ By default, the system powers up to OpenBoot firmware control before the OS is
installed.
■ The system boots to the ok prompt when the auto-boot? OpenBoot
configuration variable is set to false.
■ The system transitions to run level 0 in an orderly way when the OS is halted.
■ The system reverts to OpenBoot firmware control when the OS crashes.
■ When a serious hardware problem develops while the system is running, the OS
transitions smoothly to run level 0.
■ You deliberately place the server under firmware control in order to execute
firmware-based commands or to run diagnostic tests.
It is the last of these scenarios which most often concerns you as an administrator, since there will be times when you need to reach the ok prompt. The several ways to do this are outlined in “Entering the ok Prompt” on page 33. For detailed instructions, see “Entering the ok Prompt” on page 38.
Entering the ok Prompt
There are several ways to enter the ok prompt, depending on the state of the system and the means by which you are accessing the system console. In order of desirability, these are:
■ Graceful shutdown
■ ALOM system controller break or console command
■ L1-A (Stop-A) keys or Break key
■ Externally initiated reset (XIR)
Chapter 2 Configuring the System Console 33
Page 60
■ Manual system reset
A discussion of each method follows. For instructions, see “Entering the ok Prompt”
on page 38.
Graceful Shutdown
The preferred method of reaching the ok prompt is to shut down the OS by issuing an appropriate command (for example, the shutdown, init,oruadmin command) as described in Solaris system administration documentation. You can also use the system Power button to initiate a graceful system shutdown.
Gracefully shutting down the system prevents data loss, enables you to warn users beforehand, and causes minimal disruption. You can usually perform a graceful shutdown, provided the Solaris OS is running and the hardware has not experienced serious failure.
You can also perform a graceful system shutdown from the ALOM system controller command prompt.
For more information, see:
■ “Powering Off the Server Locally” on page 62
■ “Powering Off the System Remotely” on page 60
ALOM System Controller break or console Command
Typing break from the sc> prompt forces a running Sun Fire V445 server to move to OpenBoot firmware control. If the OS is already halted, you can use the console command instead of break to reach the ok prompt.
If you issue a break at the SC you will remain in an SC prompt. To use the OpenBoot prompt, enter the console command. For example:
hostname> #. [characters are not echoed to the screen] sc> break -y [break on its own will generate a confirmation prompt] sc> console ok
After forcing the system into OpenBoot firmware control, be aware that issuing certain OpenBoot commands (like probe-scsi, probe-scsi-all,orprobe-ide) might hang the system.
34 Sun Fire V445 Server Administration Guide • August 2006
Page 61
L1-A (Stop-A) Keys or Break Key
When it is impossible or impractical to shut down the system gracefully, you can get to the ok prompt by typing the L1-A (Stop-A) key sequence from a Sun keyboard, or, if you have an alphanumeric terminal attached to the Sun Fire V445 server, by pressing the Break key.
After forcing the system into OpenBoot firmware control, be aware that issuing certain OpenBoot commands (like probe-scsi, probe-scsi-all,orprobe-ide) might hang the system.
Note – These methods of reaching the ok prompt will only work if the system
console has been redirected to the appropriate port. For details, see “Reference for
System Console OpenBoot Configuration Variable Settings” on page 56
Externally Initiated Reset (XIR)
Use the ALOM system controller reset -x command to execute an externally initiated reset (XIR). Forcing an XIR might be effective in breaking the deadlock that is hanging up the system. However, an XIR also precludes the orderly shutdown of applications, and so it is not the preferred method of reaching the ok prompt, unless you are troubleshooting these types of system hangs. Generating an XIR has the advantage of allowing you to issue the sync command to produce a dump file of the current system state for diagnostic purposes.
For more information, see:
■ Chapter 8 and Chapter 9
■ Sun Advanced Lights Out Manager (ALOM) Online Help
Caution – Because an XIR precludes an orderly shutdown of applications, it should
only be attempted if previously described methods do not work.
Manual System Reset
Use the ALOM system controller reset command, or poweron and poweroff commands, to reset the server. Reaching the ok prompt by performing a manual system reset or by power-cycling the system should be the method of last resort. Doing this results in the loss of all system coherence and state information. A manual system reset could corrupt the server’s file systems, although the fsck command usually restores them.
Chapter 2 Configuring the System Console 35
Page 62
Caution – Forcing a manual system reset results in loss of system state data, and
should be attempted only as a last resort. After a manual system reset, all state information is lost, which inhibits troubleshooting the cause of the problem until the problem reoccurs.
Caution – When you access the ok prompt from a functioning Sun Fire V445 server,
you are suspending the Solaris OS and placing the system under firmware control. Any processes that were running under the OS are also suspended, and the state of such processes might not be recoverable.
The commands you run from the ok prompt have the potential to affect the state of the system. This means that it is not always possible to resume execution of the OS from the point at which it was suspended. The diagnostic tests you run from the ok prompt will affect the state of the system. This means that it is not possible to resume execution of the OS from the point at which it was suspended.
Although the go command will resume execution in most circumstances, in general, each time you force the system down to the ok prompt, you should expect to have to reboot the system to get back to the OS.
As a rule, before suspending the OS, you should back up files, warn users of the impending shutdown, and halt the system in an orderly manner. However, it is not always possible to take such precautions, especially if the system is malfunctioning.
For more information about the OpenBoot firmware, see the OpenBoot 4.x Command
Reference Manual. An online version of the manual is included with the OpenBoot Collection AnswerBook that ships with Solaris software.
About Switching Between the ALOM System Controller and the System Console
The Sun Fire V445 server features two management ports, labeled SERIAL MGT and NET MGT, located on the server’s back panel. If the system console is directed to use the serial management and network management ports (its default configuration), these ports provide access to both the system console and the ALOM system controller, each on separate channels (see
FIGURE 2-3).

FIGURE 2-3 Separate System Console and System Controller Channels
If the system console is configured to be accessible from the serial management and network management ports, when you connect through one of these ports you can access either the ALOM command-line interface or the system console. You can switch between the ALOM system controller and the system console at any time, but you cannot access both at the same time from a single terminal or shell tool.
The prompt displayed on the terminal or shell tool tells you which channel you are accessing:
■ The # or % prompt indicates that you are at the system console and that the
Solaris OS is running.
■ The ok prompt indicates that you are at the system console and that the server is
running under OpenBoot firmware control.
■ The sc> prompt indicates that you are at the ALOM system controller.
Note – If no text or prompt appears, it might be the case that no console messages
were recently generated by the system. If this happens, pressing the terminal’s Enter or Return key should produce a prompt.
Chapter 2 Configuring the System Console 37
Page 64
To reach the system console from the ALOM system controller, type the console command at the sc> prompt. To reach the ALOM system controller from the system console, type the system controller escape sequence, which by default is #. (pound period).
For more information, see the following:
■ “About Communicating With the System” on page 24
■ “About the sc> Prompt” on page 31

Entering the ok Prompt
This procedure provides several ways of reaching the ok prompt. The methods are not equally desirable. For details about when to use each method, see “About the ok
Prompt” on page 33.
Caution – Dropping the Sun Fire V445 server to the ok prompt suspends all
application and OS software. After you issue firmware commands and run firmware-based tests from the ok prompt, the system might not be able to resume where it left off.
▼ To Enter the ok Prompt
1. If at all possible, back up system data before starting this procedure.
For information about the appropriate backup and shutdown procedures, refer to Solaris system administration documentation.
2. Exit or stop all applications and warn users of the impending loss of service.
3. Decide which method you need to use to reach the ok prompt.
See “About the ok Prompt” on page 33 for details.

Using the Serial Management Port
This procedure assumes that the system console is directed to use the serial management and network management ports (the default configuration).
When you are accessing the system console using a device connected to the serial management port, your first point of access is the ALOM system controller and its sc> prompt. After connecting to the ALOM system controller, you can switch to the system console itself.
For more information about the ALOM system controller card, see:
■ “About the ALOM System Controller Card” on page 71
■ Sun Advanced Lights Out Manager (ALOM) Online Help
Ensure that the serial port on your connecting device is set to the following parameters:
■ 9600 baud
■ 8 bits
■ No parity
Chapter 2 Configuring the System Console 39
Page 66
■ 1 stop bit
■ No handshaking
▼ To Use the Serial Management Port
1. Establish an ALOM system controller session.
See Sun Advanced Lights Out Manager (ALOM) Online Help for instructions.
2. To connect to the system console, at the ALOM system controller command prompt, type:
sc> console
The console command switches you to the system console.
3. To switch back to the sc> prompt, type the #. escape sequence.
ok #. [characters are not echoed to the screen]
For instructions on how to use the ALOM system controller, see:
■ Sun Advanced Lights Out Manager (ALOM) Online Help
Activating the Network Management Port
You must assign an Internet Protocol (IP) address to the network management port before you can use it. If you are configuring the network management port for the first time, you must first connect to the ALOM system controller using the serial management port and assign an IP address to the network management port. You can either assign an IP address manually, or you can configure the port to obtain an IP address using the Dynamic Host Configuration Protocol (DHCP) from another server.
Data centers frequently devote a separate subnet to system management. If your data center has such a configuration, connect the network management port to this subnet.
40 Sun Fire V445 Server Administration Guide • August 2006
Page 67
Note – The network management port is a 10BASE-T port. The IP address assigned
to the network management port is a unique IP address, separate from the main Sun Fire V445 server IP address, and is dedicated for use only with the ALOM system controller. For more information, see “About the ALOM System Controller Card” on
page 71.
▼ To Activate the Network Management Port
1. Connect an Ethernet cable to the network management port.
2. Log in to the ALOM system controller through the serial management port.
For more information about connecting to the serial management port, see “Using
the Serial Management Port” on page 39.
3. Assign IP addresses by typing one of the following commands:
■ If your network uses static IP addresses, type:
sc> setsc if_network true sc> setsc netsc_ipaddr ip-address sc> setsc netsc_ipnetmask ip-address sc> setsc netsc_ipgateway ip-address
Note – The if_network command requires resetting the SC before the changes
take effect. Reset the SC with the resetsc command after changing network parameters.
■ If your network uses Dynamic Host Configuration Protocol (DHCP), type:
sc> setsc netsc_dhcp
4. Select the communications protocol, either Telnet, SSH, or none, type:.
sc> setsc if_connection none|ssh|telnet
Note – none is the default.
Chapter 2 Configuring the System Console 41
Page 68
5. To verify the network settings, type:
sc> shownetwork
6. Log out of the ALOM system controller session.
To connect through the network management port, use the telnet command to the IP address you specified in Step 3 of the preceding procedure.
Accessing the System Console With a Terminal Server
The following procedure assumes that you are accessing the system console by connecting a terminal server to the serial management port (SERIAL MGT) of the Sun Fire V445 server.
▼ To Access the System Console With a Terminal
Server Through the Serial Management Port
1. Complete the physical connection from the serial management port to your terminal server.
The serial management port on the Sun Fire V445 server is a data terminal equipment (DTE) port. The pinouts for the serial management port correspond with the pinouts for the RJ-45 ports on the Serial Interface Breakout Cable supplied by Cisco for use with the Cisco AS2511-RJ terminal server. If you use a terminal server made by another manufacturer, check that the serial port pinouts of the Sun Fire V445 server match those of the terminal server you plan to use.
If the pinouts for the server serial ports correspond with the pinouts for the RJ-45 ports on the terminal server, you have two connection options:
■ Connect a serial interface breakout cable directly to the Sun Fire V445 server. See
“Using the Serial Management Port” on page 39.
■ Connect a serial interface breakout cable to a patch panel and use the straight-
through patch cable (supplied by Sun) to connect the patch panel to the server.

For example, for a Sun Fire V445 server connected to port 10000 on a terminal server whose IP address is 192.20.30.10, you would type:
% telnet 192.20.30.10 10000
▼ To Access the System Console With a Terminal
Server Through the TTYB Port
1. Redirect the system console by changing OpenBoot configuration variables.
At the ok prompt, type the following commands:
ok setenv input-device ttyb ok setenv output-device ttyb
Note – Redirecting the system console does not redirect POST output. You can only
view POST messages from the serial and network management port devices.
Note – There are many other OpenBoot configuration variables. Although these
variables do not affect which hardware device is used to access the system console, some of them affect which diagnostic tests the system runs and which messages the system displays at its console. See Chapter 8 and Chapter 9.
44 Sun Fire V445 Server Administration Guide • August 2006
Page 71
2. To cause the changes to take effect, power off the system. Type:
ok power-off
The system permanently stores the parameter changes and powers off.
Note – You can also power off the system using the front panel Power button.
3. Connect the null modem serial cable to the TTYB port on the Sun Fire V445 server.
If required, use the DB-9 or DB-25 cable adapter supplied with the server.
4. Power on the system.
See Chapter 3 for power-on procedures.
What Next
Continue with your installation or diagnostic test session as appropriate. When you are finished, end your session by typing the terminal server’s escape sequence and exit the window.
For more information about connecting to and using the ALOM system controller, see:

▼ To Access the System Console With a Tip
Connection Throught the Serial Management Port
1. Connect the RJ-45 serial cable and, if required, the DB-9 or DB-25 adapter provided.
The cable and adapter connect between another Sun system’s serial port (typically TTYB) and the serial management port on the back panel of the Sun Fire V445 server. Pinouts, part numbers, and other details about the serial cable and adapter are provided in the Sun Fire V445 Server Parts Installation and Removal Guide.
2. Ensure that the /etc/remote file on the Sun system contains an entry for hardwire.
Most releases of Solaris OS software shipped since 1992 contain an /etc/remote file with the appropriate hardwire entry. However, if the Sun system is running an older version of Solaris OS software, or if the /etc/remote file has been modified, you might need to edit it. See “Modifying the /etc/remote File” on page 49 for details.

3. In a shell tool window on the Sun system, type:
% tip hardwire
The Sun system responds by displaying:
connected
The shell tool is now a Tip window directed to the Sun Fire V445 server through the Sun system’s serial port. This connection is established and maintained even when the Sun Fire V445 server is completely powered off or just starting up.
Note – Use a shell tool or a CDE or JDS terminal (such as dtterm), not a command
tool. Some tip commands might not work properly in a command tool window.
▼ To Access the System Console With a Tip
Connection Through the TTYB Port
1. Redirect the system console by changing the OpenBoot configuration variables.
At the ok prompt on the Sun Fire V445 server, type the following commands:
ok setenv input-device ttyb ok setenv output-device ttyb
Note – You can only access the sc> prompt and view POST messages from either
the serial management port or the network management port.
Note – There are many other OpenBoot configuration variables. Although these
variables do not affect which hardware device is used to access the system console, some of them affect which diagnostic tests the system runs and which messages the system displays at its console. See Chapter 8 and Chapter 9.

Modifying the /etc/remote File
This procedure might be necessary if you are accessing the Sun Fire V445 server using a Tip connection from a Sun system running an older version of the Solaris OS software. You might also need to perform this procedure if the /etc/remote file on the Sun system has been altered and no longer contains an appropriate hardwire entry.
This procedure assumes that you are logged in as superuser to the system console of a Sun system that you intend to use to establish a tip connection to the Sun Fire V440 server.
▼ To Modify the /etc/remote File
1. Determine the release level of Solaris OS software installed on the Sun system. Type:
# uname -r
The system responds with a release number.
2. Do one of the following, depending on the number displayed.
■ If the number displayed by the uname -r command is 5.0 or higher:
The Solaris software shipped with an appropriate entry for hardwire in the /etc/remote file. If you have reason to suspect that this file was altered and the hardwire entry modified or deleted, check the entry against the following
example, and edit it as needed.
hardwire:\
:dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
Note – If you intend to use the Sun system’s serial port A rather than serial port B,
edit this entry by replacing /dev/term/b with /dev/term/a.
Chapter 2 Configuring the System Console 49
Page 76
■ If the number displayed by the uname -r command is less than 5.0:
Check the /etc/remote file and add the following entry, if it does not already exist.
hardwire:\
:dv=/dev/ttyb:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
Note – If you intend to use the Sun system’s serial port A rather than serial port B,
edit this entry by replacing /dev/ttyb with /dev/ttya.
The /etc/remote file is now properly configured. Continue establishing a Tip connection to the Sun Fire V445 server system console. See:
■ “Accessing the System Console With a Tip Connection” on page 45
If you have redirected the system console to TTYB and want to change the system console settings back to use the serial management and network management ports, see the following:

Accessing the System Console With an Alphanumeric Terminal
This procedure assumes that you are accessing the Sun Fire V445 server system console by connecting the serial port of an alphanumeric terminal to the serial management port (SERIAL MGT) of the Sun Fire V445 server.
▼ To Access the System Console With an
Alphanumeric Terminal Through the Serial Management Port
1. Attach one end of the serial cable to the alphanumeric terminal’s serial port.
Use a null modem serial cable or an RJ-45 serial cable and null modem adapter. Plug in this cable to the terminal’s serial port connector.
2. Attach the opposite end of the serial cable to the serial management port on the Sun Fire V445 server.
3. Connect the alphanumeric terminal’s power cord to an AC outlet.
4. Set the alphanumeric terminal to receive:
■ 9600 baud
■ 8 bits
■ No parity
■ 1 stop bit
■ No handshake protocol
See the documentation accompanying your terminal for information about how to configure it.
Chapter 2 Configuring the System Console 51
Page 78
▼ To Access the System Console With an
Alphanumeric Terminal Through the TTYB Port
1. Redirect the system console by changing the OpenBoot configuration variables.
At the ok prompt, type the following commands:
ok setenv input-device ttyb ok setenv output-device ttyb
Note – You can only access the sc> prompt and view POST messages from either
the serial management port or the network management port.
Note – There are many other OpenBoot configuration variables. Although these
variables do not affect which hardware device is used to access the system console, some of them affect which diagnostic tests the system runs and which messages the system displays at its console. See Chapter 8 and Chapter 9.
2. To cause the changes to take effect, power off the system. Type:
ok power-off
The system permanently stores the parameter changes and powers off.
Note – You can also power off the system using the front panel Power button.
3. Connect the null modem serial cable to the TTYB port on the Sun Fire V445 server.
If required, use the DB-9 or DB-25 cable adapter supplied with the server.
4. Power on the system.
See Chapter 3 for power-on procedures.
You can issue system commands and view system messages using the alphanumeric terminal. Continue with your installation or diagnostic procedure, as needed. When you are finished, type the alphanumeric terminal’s escape sequence.

Verifying Serial Port Settings on TTYB
This procedure enables you to verify the baud rate and other serial port settings used by the Sun Fire V445 server to communicate with a device attached to its TTYB port.
Note – The serial management port always operates at 9600 baud, 8 bits, with no
parity and 1 stop bit.
You must be logged in to the Sun Fire V445 server, and the server must be running Solaris OS software.
▼ To Verify Serial Port Settings on TTYB
1. Open a shell tool window.
2. Type:
# eeprom | grep ttyb-mode
3. Look for the following output:
ttyb-mode = 9600,8,n,1,-
This line indicates that the Sun Fire V445 server’s serial port TTYB is configured for:
■ 9600 baud
■ 8 bits
■ No parity
■ 1 stop bit
■ No handshake protocol

Accessing the System Console With a Local Graphics Monitor
After initial system installation, you can install a local graphics monitor and configure it to access the system console. You cannot use a local graphics monitor to perform initial system installation, nor can you use a local graphics monitor to view power-on self-test (POST) messages.
To install a local graphics monitor, you must have:
■ A supported PCI-based graphics frame buffer card and software driver.
An 8/24-Bit Color Graphics PCI adapter frame buffer card (Sun part number X3768A or X3769A is currently supported)
■ A monitor with appropriate resolution to support the frame buffer
■ A Sun-compatible USB keyboard (Sun USB Type–6 keyboard)
■ A Sun-compatible USB mouse (Sun USB mouse) and mouse pad
▼ To Access the System Console With a Local
Graphics Monitor
1. Install the graphics card into an appropriate PCI slot.
Installation must be performed by a qualified service provider. For further information, see the Sun Fire V445 Server Installation Guide or contact your qualified service provider.
2. Attach the monitor’s video cable to the graphics card’s video port.
Tighten the thumbscrews to secure the connection.
3. Connect the monitor’s power cord to an AC outlet.
4. Connect the USB keyboard cable to any USB port on the Sun Fire V445 server front panel.
5. Connect the USB mouse cable to any USB port on the Sun Fire V445 server front panel.
54 Sun Fire V445 Server Administration Guide • August 2006
Page 81
6. Obtain the ok prompt.
For more information, see “Entering the ok Prompt” on page 38.
7. Set OpenBoot configuration variables appropriately.
From the existing system console, type:
ok setenv input-device keyboard ok setenv output-device screen
Note – There are many other OpenBoot configuration variables. Although these
variables do not affect which hardware device is used to access the system console, some of them affect which diagnostic tests the system runs and which messages the system displays at its console. See Chapter 8 and Chapter 9.
8. To cause the changes to take effect, type:
ok reset-all
The system stores the parameter changes, and boots automatically when the OpenBoot configuration variable auto-boot? is set to true (its default value).
Note – To store parameter changes, you can also power cycle the system using the
Power button.
You can issue system commands and view system messages using your local graphics monitor. Continue with your installation or diagnostic procedure, as needed.
If you want to redirect the system console back to the serial management and network management ports, see:
■ “Reference for System Console OpenBoot Configuration Variable Settings” on
page 56
Chapter 2 Configuring the System Console 55
Page 82
Reference for System Console OpenBoot Configuration Variable Settings
The Sun Fire V445 system console is directed to the serial management and network management ports (SERIAL MGT and NET MGT) by default. However, you can redirect the system console to the serial DB-9 port (TTYB), or to a local graphics monitor, keyboard, and mouse. You can also redirect the system console back to the serial management and network management ports.
Certain OpenBoot configuration variables control from where system console input is taken and to where its output is directed. The table below shows how to set these variables in order to use the serial management and network management ports, TTYB, or a local graphics monitor as the system console connection.
TABLE 2-4 OpenBoot Configuration Variables That Affect the System Console
System Console Output
Serial and OpenBoot Configuration Variable Name
output-device ttya ttyb screen
Network
Management Ports Serial Port (TTYB)
Local Graphics
*
Monitor
*
input-device ttya ttyb keyboard
* POST output will still be directed to the serial management port, as POST has no mechanism to direct its output
to a graphics monitor.
The serial management port and network management port are present in the OpenBoot configuration variables as ttya. However, the serial management port does not function as a standard serial connection. If you want to connect a conventional serial device (such as a printer) to the system, you need to connect it to TTYB, not the serial management port. See “About the Serial Ports” on page 90 for more information.
The sc> prompt and POST messages are only available through the serial management port and network management port. In addition, the ALOM system controller console command is ineffective when the system console is redirected to TTYB or a local graphics monitor.
In addition to the OpenBoot configuration variables described in
TABLE 2-4, there are
other variables that affect and determine system behavior. These variables are created during system configuration and stored on a ROM chip.

4. Wait for the system to power off.
The power supply Power OK indicators extinguish when the system is powered off.
Caution – Ensure no other users have access to power on the system or system
components while working on internal components.
Initiating a Reconfiguration Boot
After installing any new internal option or external storage device, you must perform a reconfiguration boot so that the OS is able to recognize newly installed devices. 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 for
62 Sun Fire V445 Server Administration Guide • August 2006
Page 89
the OS to recognize the configuration change. This requirement also applies to any component that is connected to the system I
2
C bus to ensure proper environmental
monitoring.
This requirement does not apply to any component that is:
■ Installed or removed as part of a hot-plug operation
■ Installed or removed before the OS is installed
■ Installed as an identical replacement for a component that is already recognized
by the OS
To issue software commands, you need to set up an alphanumeric terminal connection, a local graphics monitor connection, ALOM system controller connection, or a Tip connection to the Sun Fire V445 server. See Chapter 2 for more information about connecting the Sun Fire V445 server to a terminal or similar device.
This procedure assumes that you are accessing the system console using the serial management or network management port.
For more information, see:
■ “About Communicating With the System” on page 24
■ “About the sc> Prompt” on page 31
■ “About the ok Prompt” on page 33
■ “About Switching Between the ALOM System Controller and the System
Console” on page 36
■ “Entering the ok Prompt” on page 38
▼ To Initiate a Reconfiguration Boot

boot process to access the system ok prompt.
The system banner contains the Ethernet address and host ID. To stop the boot process, use one of the following methods:
■ Hold down the Stop (or L1) key and press A on your keyboard.
■ Press the Break key on the terminal keyboard.
■ Type the break command from the sc> prompt.
7. At the ok prompt, type the following commands:
ok setenv auto-boot? false ok reset-all
You must set the auto-boot? variable to false and issue the reset-all command to ensure that the system correctly initiates upon reboot. If you do not issue these commands, the system might fail to initialize, because the boot process was stopped in Step 6.
8. At the ok prompt, type the following command:
ok setenv auto-boot? true
You must set auto-boot? variable back to true so that the system boots automatically after a system reset.
9. At the ok prompt, type the following command:
ok boot -r
The boot -r command rebuilds the device tree for the system, incorporating any newly installed options so that the OS will recognize them.
Note – A system banner appears in 30 seconds to 20 minutes. This time depends on
the system configuration (number of CPUs, memory modules, PCI cards) and the level of POST and OpenBoot Diagnostics tests being performed. For more information about OpenBoot configuration variables, see Appendix C.
The system front panel LED indicators provide power-on status information. For information about the system indicators, see:

If the system encounters a problem during startup (running in the normal mode), try restarting the system in Diagnostics mode to determine the source of the problem. Use ALOM or the OpenBoot Prompt (ok prompt) to switch to Diagnostics mode and power cycle the system. See “Powering Off the Server Locally” on page 62.
For information about system diagnostics and troubleshooting, see Chapter 8.
Selecting a Boot Device
You specify the boot device by setting an OpenBoot configuration variable called boot-device. The default setting of this variable is disk net. With this setting, the firmware first attempts to boot from the system hard disk drive, and if that fails, from the on-board net0 Gigabit Ethernet interface.
Before you can select a boot device, you must complete system installation according to the instructions in the Sun Fire V445 Server Installation Guide.
This procedure assumes that you are familiar with the OpenBoot firmware and that you know how to enter the OpenBoot environment. For more information, see:
■ “About the ok Prompt” on page 33
Note – The serial management port on the ALOM system controller card is
preconfigured as the default system console port. For more information, see
Chapter 2.
If you want to boot from a network, you must connect the network interface to the network. See, “Attaching a Twisted-Pair Ethernet Cable” on page 131.
▼ To Select a Boot Device
● At the ok prompt, type:
ok setenv boot-device device-specifier
where the device-specifier is one of the following:
■ cdrom – Specifies the DVD-ROM drive
■ disk – Specifies the system boot disk (internal disk 0 by default)
■ disk0 – Specifies internal disk 0
■ disk1 – Specifies internal disk 1
Chapter 3 Powering On and Powering Off the System 65
Page 92
■ disk2 – Specifies internal disk 2
■ disk3 – Specifies internal disk 3
■ disk4 – Specifies internal disk 4
■ disk5 – Specifies internal disk 5
■ disk6 – Specifies internal disk 6
■ disk7 – Specifies internal disk 6
■ net, net0, net1– Specifies the network interfaces
■ full path name – Specifies the device or network interface by its full path name
Note – The Solaris OS modifies the boot-device variable to its full path name, not
the alias name. If you choose a nondefault boot-device variable, the Solaris OS specifies the full device path of the boot device.
Note – You can also specify the name of the program to be booted as well as the
way the boot program operates. For more information, see the OpenBoot 4.x Command Reference Manual in the OpenBoot Collection AnswerBook for your specific
Solaris OS release.
If you want to specify a network interface other than an on-board Ethernet interface as the default boot device, you can determine the full path name of each interface by typing:
ok show-devs
The show-devs command lists the system devices and displays the full path name of each PCI device.
For more information about using the OpenBoot firmware, refer to the OpenBoot 4.x Command Reference Manual in the OpenBoot Collection AnswerBook for your specific Solaris release.

About the CPU/Memory Modules
The system motherboard provides slots for up to four CPU/memory modules. Each CPU/memory module incorporates one UltraSPARC IIIi processor, and slots for up to four dual inline memory modules (DIMMs). The CPUs in the system are numbered from 0 to 3, depending on the slot where each CPU resides.
67
Page 94
Note – CPU/memory modules on a Sun Fire V445 server are not hot-pluggable or
hot-swappable.
The UltraSPARC IIIi processor is a high-performance, highly integrated superscalar processor implementing the SPARC V9 64-bit architecture. The UltraSPARC IIIi processor can support both 2D and 3D graphics, as well as image processing, video compression and decompression, and video effects through the sophisticated Visual Instruction Set extension (Sun VIS software). The VIS software provides high levels of multimedia performance, including two streams of MPEG-2 decompression at full broadcast quality with no additional hardware support.
The Sun Fire V445 server employs a shared-memory multiprocessor architecture with all processors sharing the same physical address space. The system processors, main memory, and I/O subsystem communicate via a high-speed system interconnect bus. In a system configured with multiple CPU/memory modules, all main memory is accessible from any processor over the system bus. The main memory is logically shared by all processors and I/O devices in the system. However, memory is controlled and allocated by the CPU on its host module, that is, the DIMMs on CPU/memory module 0 are managed by CPU 0.
DIMMs
The Sun Fire V445 server uses 2.5-volt, high-capacity double data rate dual inline memory modules (DDR DIMMs) with error-correcting code (ECC). The system supports DIMMs with 512-Mbyte, 1-Gbyte, and 2-Gbyte capacities. Each CPU/memory module contains slots for four DIMMs. Total system memory ranges from a minimum of 1 Gbyte (one CPU/memory module with two 512-Mbyte DIMMs) to a maximum of 32 Gbytes (four modules fully populated with 2-Gbyte DIMMs).
Within each CPU/memory module, the four DIMM slots are organized into groups of two. The system reads from, or writes to, both DIMMs in a group simultaneously. DIMMs, therefore, must be added in pairs. The figure below shows the DIMM slots and DIMM groups on a Sun Fire V445 server CPU/memory module. Adjacent slots belong to the same DIMM group. The two groups are designated 0 and 1 as shown in
FIGURE 4-1.
68 Sun Fire V445 Server Administration Guide • August 2006
Page 95
1010
DIMM group 1
FIGURE 4-1 Memory Module Groups 0 and 1
TABLE 4-1 lists the DIMMs on the CPU/memory module, and to which group each

DIMM belongs.
TABLE 4-1 Memory Module Groups 0 and 1
Label Group Physical Group
B1/D1 B1 1 (must be installed as a pair)
B1/D0
B0/D1 B0 0 (must be installed as a pair)
B0/D0
The DIMMs must be added in pairs within the same DIMM group, and each pair used must have two identical DIMMs installed – that is, both DIMMs in each group must be from the same manufacturer and must have the same capacity (for example, two 512-Mbyte DIMMs or two 1-Gbyte DIMMs).
Note – Each CPU/memory module must be populated with a minimum of two
DIMMs, installed in either group 0 or group 1.
Caution – DIMMs are made of electronic components that are extremely sensitive
to static electricity. Static from your clothes or work environment can destroy the modules. Do not remove a DIMM from its antistatic packaging until you are ready to install it on the CPU/memory module. Handle the modules only by their edges. Do
Chapter 4 Configuring Hardware 69
Page 96
not touch the components or any metal parts. Always wear an antistatic grounding strap when you handle the modules. For more information, refer to the Sun Fire V445 Server Installation Guide and the Sun Fire V445 Server Service Manual.
For guidelines and complete instructions on how to install and identify DIMMs in a CPU/memory module, refer to the Sun Fire V445 Server Service Manual and the Sun Fire V445 Server Installation Guide.
Memory Interleaving
You can maximize the system’s memory bandwidth by taking advantage of its memory interleaving capabilities. The Sun Fire V445 server supports two-way interleaving. In most cases, higher interleaving results in improved system performance. However, actual performance results can vary depending on the system application. Two-way interleaving occurs automatically in any DIMM bank where the DIMM capacities in DIMM group 0 match the capacities used in a DIMM group 1. For optimum performance, install identical DIMMs in all four slots in a CPU/memory module.
Independent Memory Subsystems
Each Sun Fire V445 server CPU/memory module contains an independent memory subsystem. Memory controller logic incorporated into the UltraSPARC IIIi CPU allows each CPU to control its own memory subsystem.
The Sun Fire V445 server uses a shared memory architecture. During normal system operations, the total system memory is shared by all CPUs in the system.

DIMM Configuration Rules
■ You must physically remove a CPU/memory module from the system before you
can install or remove DIMMs.
■ You must add DIMMs in pairs.
■ Each group used must have two identical DIMMs installed – that is, both DIMMs
must be from the same manufacturer and must have the same density and capacity (for example, two 512-Mbyte DIMMs or two 1-Gbyte DIMMs).
■ For maximum memory performance and to take full advantage of the Sun Fire
V445 server’s memory interleaving features, use identical DIMMs in all four slots of a CPU/memory module.
For information about installing or removing DIMMs, see the Sun Fire V445 Server
Parts Installation and Removal Guide.
About the ALOM System Controller Card
The Sun Advanced Lights Out Manager (ALOM) system controller card enables access, monitoring, and control of the Sun Fire V445 server from a remote location. It is a fully independent processor card with its own resident firmware, self­diagnostics, and OS.
In addition, the ALOM system controller card functions as the default console connection to the system, through its serial management port. For more information about using the ALOM system controller as the default console connection, see:
■ “About Communicating With the System” on page 24
■ “Using the Serial Management Port” on page 39
When you first power on the system, the ALOM system controller card provides a default connection to the system console through its serial management port. After initial setup, you can assign an IP address to the network management port and connect the network management port to a network. You can run diagnostic tests, view diagnostic and error messages, reboot your server, and display environmental status information using the ALOM system controller software. Even if the operating system is down or the system is powered off, the ALOM system controller can send an email alert about hardware failures, or other important events that can occur on the server.
The ALOM system controller provides the following features:
■ Secure Shell (SSH) or Telnet connectivity – Network connectivity can also be
disabled
Chapter 4 Configuring Hardware 71
Page 98
■ Remote powering on/off the system and diagnostics
■ Default system console connection through its serial management port to an
alphanumeric terminal, terminal server, or modem
■ Network management port for remote monitoring and control over a network,
after initial setup
■ Remote system monitoring and error reporting, including diagnostic output
■ Remote reboot, power-on, power-off, and reset functions
■ Ability to monitor system environmental conditions remotely
■ Ability to run diagnostic tests using a remote connection
■ Ability to remotely capture and store boot and run logs, which you can review or
replay later
■ Remote event notification for overtemperature conditions, power supply faults,
system shutdown, or system resets
■ Remote access to detailed event logs

The ALOM system controller card features serial and 10BASE-T Ethernet interfaces that provide multiple ALOM system controller software users with simultaneous access to the Sun Fire V445 server. ALOM system controller software users are provided secure password-protected access to the system’s Solaris and OpenBoot console functions. ALOM system controller users also have full control over power­on self-test (POST) and OpenBoot Diagnostics tests.

Caution – Although access to the ALOM system controller through the network
management port is secure, access through the serial management port is not secure. Therefore, avoid connecting a serial modem to the serial management port.
Note – The ALOM system controller serial management port (labeled SERIAL
MGT) and network management port (labeled NET MGT) are present in the Solaris OS device tree as /dev/ttya, and in the OpenBoot configuration variables as ttya. However, the serial management port does not function as a standard serial connection. If you want to attach a standard serial device to the system (such as a printer), you need to use the DB-9 connector on the system back panel, which corresponds to /dev/ttyb in the Solaris device tree, and as ttyb in the OpenBoot configuration variables. See “About the Serial Ports” on page 90 for more information.
The ALOM system controller card runs independently of the host server, and operates off of standby power from the server power supplies. The card features on-board devices that interface with the server environmental monitoring subsystem and can automatically alert administrators to system problems. Together, these features enable the ALOM system controller card and ALOM system controller software to serve as a lights out management tool that continues to function even when the server OS goes offline or when the server is powered off.
The ALOM system controller card plugs in to a dedicated slot on the motherboard and provides the following ports (as shown in
FIGURE 4-3) through an opening in the
system’s back panel:
■ Serial communication port via an RJ-45 connector (serial management port,
labeled SERIAL MGT)
■ 10-Mbps Ethernet port via an RJ-45 twisted-pair Ethernet (TPE) connector
(network management port, labeled NET MGT) with green Link/Activity indicator

Configuration Rules
Caution – The system supplies power to the ALOM system controller card even
when the system is powered off. To avoid personal injury or damage to the ALOM system controller card, you must disconnect the AC power cords from the system before servicing the ALOM system controller card. The ALOM system controller card is not hot-swappable or hot-pluggable.
■ The ALOM system controller card is installed in a dedicated slot on the system
motherboard. Never move the ALOM system controller card to another system slot, because it is not a PCI-compatible card. In addition, do not attempt to install a PCI card into the ALOM system controller slot.
■ Avoid connecting a serial modem to the serial management port because it is not
secure.
■ The ALOM system controller card is not a hot-pluggable component. Before
installing or removing the ALOM system controller card, you must power off the system and disconnect all system power cords.
■ The serial management port on the ALOM system controller cannot be used as a
conventional serial port. If your configuration requires a standard serial connection, use the DB-9 port labeled “TTYB” instead.
■ The 100BASE-T network management port on the ALOM system controller is
reserved for use with the ALOM system controller and the system console. The network management port does not support connections to Gigabit networks. If
