1 Introduction The Dell™ PowerEdge™ systems baseboard management controller (BMC) monitors the system for critical events by communicating with various sensors on the system board and sends alerts and log events when certain parameters exceed their preset thresholds. The BMC supports the industry-standard Intelligent Platform Management Interface (IPMI) specification, enabling you to configure, monitor, and recover systems remotely.
www.dell.com | support.dell.com Supported System The BMC-management features documented in this guide are supported on the following Dell PowerEdge system: • 7250 BMC Configuration and Management Tasks This user’s guide documents the basic tasks needed to set up and configure the BMC on a managed system in preparation for using the BMC Management Utility.
Figure 1-1.
www.dell.com | support.dell.com Basic BMC Alerting Over a Shared LAN If you plan to only use your system’s BMC functionality to monitor BMC Alerts using IT Assistant, you will need follow the BMC configuration guidelines listed in Table 1-1. Table 1-1.
Table 1-3.
www.dell.com | support.dell.com BMC Configuration and Management Tools Using the System Maintenance Utility The System Maintenance Utility is an EFI-based program that provides the ability to view or modify the systems management firmware configuration, which is maintained by the BMC. The SMU lets you: • Configure the serial channel for remote systems management over a direct serial connection. • Configure the LAN channel for remote systems management over the network.
Using Sever Administrator Server Administrator Version 1.8.3 provides a convenient and easy-to-use graphical user interface for remotely configuring or managing your system’s BMC on a system running a supported operating system. The Server Administrator Instrumentation Service can be used to configure the most relevant BMC features. In addition, Server Administrator can be utilized as command line interface. Server Administrator requires that the system has an operating system installed and functioning.

For more information about these help tools, see "Getting Help" in your system's Installation and Troubleshooting Guide. Additionally, Dell Enterprise Training and Certification is available; see www.dell.com/training for more information.
2 Configuring Your Managed System In order to use the BMC Management Utility, you must first configure the necessary system BIOS, network, and serial connection settings to enable access to the BMC. In addition, to utilize the BMC Management Utility IPMI Serial functions, you must have a working connection between the management station and the correct serial I/O port of the managed system, using a null modem cable.
www.dell.com | support.dell.com Table 2-1.
Table 2-2. Setup Console Redirection Submenu Items (continued) Submenu Item Default Value Description Flow Control No Flow Control [CTS/RTS] CTS/RTS + CD No flow control. CTS/RTS = Hardware-based flow control. CTS/RTS +CD = Hardware-based + carrier-detect flow control. When the BMC Management Utility is sharing the COM port as console redirection, the flow control must be set to CTS/RTS or CTS/RTS+CD depending on whether a modem is used. XON/XOFF Xon/Xoff = Software-based flow control.
www.dell.com | support.dell.com Configuring Your Managed System with the System Maintenance Utility (SMU) NOTE: The SMU can be run from both the Resource CD and from the system’s utility partition (UT). See the System Software Guide on the Resource CD for instructions on running the SMU from the UT. The managed system must have a CD drive. A network connection is not required.
User Configuration Subtask The User Configuration subtask provides a way to configure the user access to the LAN and Serial channels. Up to four users are allowed. Some of the options presented in these screens depend on how the channels have been configured; therefore, the channels should be configured before you access these settings. Sessions allow a framework for user authentication and allow multiple IPMI messaging streams on a single channel.
www.dell.com | support.dell.com Otherwise, the firmware attempts to use the first entry in the user table that it finds that allows access to the specified channel and would expect the password associated with that entry to be the one entered to gain access to the specified channel. The figure below shows the screen that is displayed when a User Name is selected and then the Edit button is clicked. Changes made to user settings do not take effect until the next time that the user establishes a session.
The password can be from 1 to 16 ASCII characters long. The characters accepted by the SMU for usernames are the ASCII printable characters in the range 0x21 through 0x7e, except for left and right bracket characters ('[' and ']'). These characters are reserved for framing packets for terminal mode sessions. Clear Password This check box is used to clear the password for the user. If this box is checked, the Enter and Verify New Password edit boxes are disabled.
www.dell.com | support.dell.com Figure 2-3. LAN Channel Configuration Screen After completing this screen, click Next to move to the next screen to continue this sub-task. Default LAN Configuration Settings Set by the SMU The SMU automatically configures some server management firmware settings. These are not displayed on the screen above, but are listed below.
Access Mode This drop-down box configures the access mode for the LAN channel. The available options are: • Always Available: The channel is dedicated to communication with the BMC and is available during all system states (powered-down, powered-up, pre-boot, sleep, run-time, etc.). • Disabled: The channel is not allowed to communicate with the BMC. BMC Privilege Level Limit This drop-down box determines the maximum privilege level at which communication on the channel can take place.
www.dell.com | support.dell.com Host IP Address This edit box is for the logical or Internet address of the host. The IP address is required when DHCP is disabled. The IP address is entered as a dotted notation, such as 192.168.0.2. Subnet Mask The edit box is for the host's subnet mask. The system uses this to decide if alert destinations are in the local subnet or in another subnet relative to the client console. The Subnet Mask is entered as a dotted notation, such as 255.255.0.0.
Backup Gateway MAC Address This edit box allows you to enter the MAC address of the backup gateway router. The MAC address is entered as a series of six pairs of hex digits separated by dashes, such as 00-01-62-d0-3e-66. Alphabetic hex digits (a-f) can be entered in uppercase or lowercase. This edit box is disabled by default and is only activated if the check box for Automatically resolve Backup Gateway MAC address is not checked.
www.dell.com | support.dell.com Figure 2-4. Serial Over LAN Configuration Screen After configuring the SOL information, click Save to complete this subtask. Enable Serial Over LAN This check box is used to enable or disable the serial over LAN capability. SOL Privilege Level This setting is used to select the minimum BMC privilege level that is required to be able to activate SOL. The choices are User, Operator, and Administrator. For the best performance, User should be selected.
Baud Rate This field sets the baud rate at which serial data is transferred by the BMC when SOL is active. The choices are Default IPMI, 9600 bps, 19.2 kbps, 38.4 kbps, 57.6 kbps, and 115.2 kbps. If Default IPMI is selected, the baud rate used is the rate currently set for BIOS serial redirection. When SOL is active, serial communication with the BMC always occurs with 8 data bits, no parity, 1 stop bit, and RTS/CTS (hardware) flow control.

3 BMC Management Utility The BMC Management Utility is comprised of a collection of software applications that enable remote management and configuration of systems equipped with a BMC. The BMC Management Utility includes the following components: • Command Line Interface (IPMI Shell) The IPMI Shell is a scriptable console application program for the control and management of remote systems using the IPMI 1.5 protocol. The IPMI Shell supports both serial access and LAN access to the BMC.
www.dell.com | support.dell.com Installing the BMC Management Utility The BMC Management Utility is installed on a management station system in order to remotely connect to the managed system’s BMC. See Figure 3-1. Installation Prerequisites Before using the BMC Management Utility, you must perform at least the basic BIOS and BMC configuration tasks described in "Configuring Your Managed System.
Installation To install the BMC Management Utility on the management station, perform the following steps: 1 Log on with administrator privileges to the system where you want to install the system management software components. 2 Exit any open application programs and disable any virus-scanning software. 3 Insert the Systems Management and Documentation CD into your system's CD drive. The setup program should start automatically.
www.dell.com | support.dell.com The SOL Proxy will start automatically during system startup. Alternatively, you can go to directory /etc/init.d and use the following command to manage the SOL Proxy service: solproxy status solproxy start solproxy stop solproxy restart Uninstalling the BMC Management Utility To uninstall the BMC Management Utility, perform the following procedures: 1 Log in as root. 2 Enter the following command to remove all the installed packages.
In addition to the operations that can be performed by a user with operator-level BMC user privileges, IPMI Shell allows a user with administrator-level BMC user privileges to: • Set and change user privileges. To facilitate command scripting, upon successful execution IPMI Shell terminates with an exit code of zero, and will output the execution results in a parsable format. If an error is encountered, the program exits with a non-zero error code and output the error in a parsable format.
www.dell.com | support.dell.com Using IPMI Shell To use IPMI Shell, perform the following steps: On systems running a supported Microsoft Windows operating system: 1 Start a Command Prompt window. 2 Go to the directory where the file ipmish.exe is located. By default, ipmish.exe is located at the directory: C:\ProgramFiles\ Dell\OpenManage\bmcconsole. 3 Enter IPMI Shell commands (see "IPMI Shell Command Syntax") to manage the remote system.
IPMI Shell Global Options IPMI Shell has the following global options: IPMI Session Option -ip Synopsis ipmish -ip bmc_ip_address | bmc_hostname -u username -p password Description This option is used to establish a connection to a remote managed system using the LAN channel. The IP port specified in installation (default value is 623) is used unless another port has been configured. Options NOTE: The following options cannot be used independently. One or more IPMISH command must follow the option.
www.dell.com | support.dell.com Options NOTE: The following options cannot be used independently. One or more IPMISH command must follow the option. -com serial_port Specifies the serial port used when establishing an IPMI session to the managed system. For a system running Windows, the management station port can be 1, 2, 3, and so on. For systems running Red Hat Linux, the management station port can be ttyS0, ttyS1, ttyS2, and so on.

Figure 3-6. sysinfo Option Example power Synopsis power status power off [-force] | on | cycle | reset Description This command is used to display the current power status of the managed system, turn the system on or off, or reset the system. See Figure 3-7.
Subcommands status — Displays the current power status of the system, the returned value is “on” or “off”. on — Turns on the managed system. off — Issues a “graceful shutdown” IPMI command. NOTE: The off subcommand is not supported on the PowerEdge 7250. You must use the force option to turn off the system. cycle — Turns off the system, pauses, then turns the system back on. reset — Pulses the system reset signal, regardless of the power state.
www.dell.com | support.dell.com sel Synopsis sel status sel get [ [-begin index1 ] [-end index2 | -max count] ] | [-last n] sel clear Description This command is used to display event log information, display the contents of the event log, and delete all the event log records. See Figure 3-8. Subcommands status — Displays the total number of system event log records. get — Prints all or part of the event log. clear — Deletes all the records in the event log.
Figure 3-8. sel Option Example SOL Proxy SOL Proxy is a simple telnet server. It allows a telnet client to interact with the hardwaredesignated serial port of a remote managed system using the LAN communication channel. See Figure 3-9. With SOL Proxy, administrators can view and change the BIOS settings over a shared LAN. In addition, you can also access your managed system’s BMC using SOL Proxy using the Red Hat Linux serial console and Microsoft’s EMS/SAC interfaces.
www.dell.com | support.dell.com Figure 3-9. SOL Proxy Diagram The SOL Proxy communication scheme enables the viewing and configuration of the BIOS settings of a managed system, as well as resetting the managed system remotely using a telnet client. SOL Proxy is installed as a daemon service and automatically starts each time the system boots. SOL Proxy can accommodate only one telnet session at a time. A variety of telnet clients can be used to access SOL Proxy features.
NOTE: When using HyperTerminal, uncheck the Wrap lines that exceed terminal width check box to avoid console redirected data that may appear to be corrupted or garbled. To uncheck this feature, click File→ Properties→ Settings→ ASCII Setup…→ Wrap lines that exceed terminal width. NOTE: See "Using Console Redirection" for more information about console redirection, including hardware and software requirements and instructions for configuring host and client systems to use console redirection.
www.dell.com | support.dell.com Using Windows HyperTerminal Console To connect and use SOL Proxy: 1 Open a HyperTerminal session on your management station. 2 Create a new TCP/IP connection, providing the IP address of SOL Proxy Server and the port number you have specified in SOL Proxy installation (the default value is 623). The Emulation mode is VT100 and ANSI. NOTE: The IP address and port number you provide should conform to the ones defined in the SOL Proxy configuration file.
5 After authentication is performed, you will see a login successful message and the SOL Proxy main menu prompt. You are ready to use SOL Proxy. See "SOL Proxy Main Menu" for further instructions. SOL Proxy Main Menu After the telnet connection with SOL Proxy is successfully established, you are presented with the following menu of choices. See Figure 3-10. Figure 3-10.
www.dell.com | support.dell.com Menu option 2 allows you to enable, disable, and configure the SOL defaults, including the minimum user privilege level required for activating SOL and the communication baud-rate. Menu options 3 and 4 allow you to establish a SOL remote console session through the SOL Proxy main menu. Menu option 3 establishes a SOL session without changing the remote system’s state. This option is ideal for connecting to the Microsoft SAC/EMS or the Red Hat Linux console.

There are certain SOL parameters that the user can set by modifying the solproxy.cfg file. The parameters and their descriptions are as follow: Comments Any line starting with a “#” is treated as a comment. For example: #The file is an example.
www.dell.com | support.dell.com IP address ip — specifies the specific IP address used to connect to the SOL Proxy. This item defines what kind of connection can be accepted to establish a SOL Proxy telnet session. There are three possible values: • INADDR_ANY — SOL Proxy accepts the telnet request to any system. • 127.0.0.1 — SOL Proxy accepts the telnet request to the localhost. • IP address — SOL Proxy accepts the telnet request to the specified IP address.
Retry Interval retry_interval — specifies the period of time in seconds that the BMC waits before it retries sending a packet. The retry_interval unit is half a second. Therefore, a value of 2 means that the software waits one second for the BMC to respond before it tries to resend the packet, a value of 4 means that it waits two seconds, and so on.

4 Known Issues and Frequently Asked Questions Q: Do IPMI Shell commands correspond one-to-one to IPMI commands? A: IPMI Shell provides only the most useful IPMI commands. It includes a definitive set of commands that can be used to accomplish the most common management tasks. Therefore, IPMI Shell commands may not correspond one-to-one to IPMI commands.
www.dell.com | support.dell.com Q: Why can’t I connect to a console using the terminal emulation software included with my Microsoft Windows operating system? A: The version of HyperTerminal included with Windows does not provide many functions required during console redirection. Either upgrade to HyperTerminal Private Edition 6.1 or later, or select any other terminal emulation software that supports VT100 or ANSI emulation mode.

B Using Console Redirection Console redirection allows you to manage a host (local) system from a client (remote) system by redirecting keyboard input and text output through a serial port. You cannot redirect graphic output. You can use console redirection for tasks such as configuring BIOS settings. You can also connect the client system to a port concentrator that can access numerous host systems using a shared modem.
www.dell.com | support.dell.com Configuring the Client System After configuring the host system, configure the ports and terminal settings for the client (remote) system. NOTE: The examples in this section assume that you have upgraded to Hilgraeve's HyperTerminal Private Edition 6.1 or later. If you are using other terminal emulation software, see the documentation for that software.
Managing the Host System Remotely After you configure the host and client systems (see "Configuring the Host System" and "Configuring the Client System"), you can use console redirection to restart a host system or to change a host system's configuration settings. 1 Reboot the host system using the client system. See "Configuring Special Key Functions" for instructions.

C Terminal Mode Commands Terminal mode allows you to directly interface to the server's Baseboard Management Controller (BMC) using a serial port connection and execute text-based commands. Two types of text commands are supported: • A limited selection of text commands • Standard binary IPMI 1.
www.dell.com | support.dell.com Each terminal mode message must be preceded with the left bracket "start” character and must be ended with a right bracket “stop” character and the appropriate input new-line sequence. No input characters are accepted until the start character has been received. Terminal mode text commands are case sensitive, but hex-ASCII commands can either use upper or lower case letters for ASCII representations of hex digits.
The software ID and LUN for the remote console are fixed and implied by the command. The SWID for messages to the remote console is always 47h, and the Logical Unit Number (LUN) is 00b. Instead, there is a "bridge" field that is used to identify whether the message should be routed to the BMC’s bridged message tracking or not. See "Terminal Mode IPMI Message Bridging" for more information. Table C-1.
www.dell.com | support.dell.com Text command example: [SYS TMODE] [OK TMODE] Terminal Mode IPMI Message Bridging Terminal mode supports the ability to bridge IPMI messages to another interface when binary hex-ASCII IPMI commands are used. The message bridge is determined by the following: the bridge field, whether the message is a request or a response, the message direction with respect to the BMC and the LUN. Table C-3 lists the supported BMC combinations for IPMI message bridging.
Table C-4. Terminal Mode Text Commands Command Switches Description SYS PWD -U USERNAME Used to activate a terminal mode session. USERNAME corresponds to the ASCII text for the username. represents a printable password (up to 16 characters). If is not provided, then a Null password (all binary 0’s) is submitted.

Glossary The following list defines or identifies technical terms, abbreviations, and acronyms used in your system documents. adapter card An expansion card that plugs into an expansion-card connector on the system's system board. An adapter card adds some specialized function to the system by providing an interface between the expansion bus and a peripheral device. Examples of adapter cards include network cards, sound cards, and SCSI adapters.
www.dell.com | support.dell.com BIOS Acronym for basic input/output system. Your system's BIOS contains programs stored on a flash memory chip. The BIOS controls the following: • Communications between the microprocessor and peripheral devices, such as the keyboard and the video adapter • Miscellaneous functions, such as system messages bit The smallest unit of information interpreted by your system.
COMn The device names for the first through fourth serial ports on your system are COM1, COM2, COM3, and COM4. The default interrupt for COM1 and COM3 is IRQ4, and the default interrupt for COM2 and COM4 is IRQ3. Therefore, you must be careful when configuring software that runs a serial device so that you don't create an interrupt conflict. config.sys file The config.sys file is executed when you boot your system (before running any commands in the autoexec.bat file).
www.dell.com | support.dell.com DRAC II EPROM DRAC III ERA DRAC III/XT ERA/MC Acronym for Dell™ OpenManage Remote Assistant Card, version 2. Acronym for Dell Remote Access Card III. Acronym for Dell Remote Access Card III/XT. DRAM Acronym for dynamic random-access memory. A system's RAM is usually made up entirely of DRAM chips. Because DRAM chips cannot store an electrical charge indefinitely, your system continually refreshes each DRAM chip in the system.
FAT file system. The operating system maintains a table to keep track of the status of various segments of disk space used for file storage. • FAT32 — A derivative of the FAT file system. FAT32 supports smaller cluster sizes than FAT, thus providing more efficient space allocation on FAT32 drives. FEPROM Acronym for flash erasable programmable read-only memory. Flash memory is a kind of nonvolatile storage device similar to EEPROM, but the erasing is done only in blocks or the entire chip.
www.dell.com | support.dell.com integrated host adapter circuitry.) To add a SCSI expansion bus to your system, you must install or connect the appropriate host adapter. includes a 16-KB internal cache, which is set up as an 8-KB read-only instruction cache and an 8-KB read/write data cache. HPFS IP address HTTP IPMI Abbreviation for the High Performance File System option in the Windows NT operating systems. Abbreviation for Hypertext Transfer Protocol.
local bus On a system with local-bus expansion capability, certain peripheral devices (such as the video adapter circuitry) can be designed to run much faster than they would with a traditional expansion bus. Some local-bus designs allow peripherals to run at the same speed and with the same width data path as the system's microprocessor. LPTn The device names for the first through third parallel printer ports on your system are LPT1, LPT2, and LPT3. LRA Abbreviation for local response agent.
www.dell.com | support.dell.com NVRAM Acronym for nonvolatile random-access memory. Memory that does not lose its contents when you turn off your system. NVRAM is used for maintaining the date, time, and system configuration information. option An argument to a command that modifies its function rather than providing data and is usually set off by a delimiter such as - or /.
RAM disk A memory-resident program that emulates a hard drive. read-only file A read-only file is one that you are prohibited from editing or deleting. A file can have read-only status if: • Its read-only attribute is enabled. • It resides on a physically write-protected diskette or on a diskette in a write-protected drive. • It is located on a network in a directory to which the system administrator has assigned read-only rights to you.
www.dell.com | support.dell.com managed system or about potential hardware problems. SOL Abbreviation for Serial Over LAN. SOL enables suitably designed servers to transparently redirect the serial character stream of a baseboard UART to/from a remote client over a shared LAN. The architecture requires software running on the managed system’s BMC and client software running on a management station and/or a central network proxy. support commands Commands that specify how an action should be performed.
the upper memory area, in which you can load device drivers and memory-resident programs. drive, the operating system would manage the system as though it had 32 MB of physical RAM. URL VT-100 USB WAN Abbreviation for Uniform Resource Locator (formerly Universal Resource Locator). Abbreviation for Universal Serial Bus. A USB connector provides a single connection point for multiple USBcompliant devices, such as mice, keyboards, printers, and computer speakers.
