Using Console Redirection Dell PowerEdge 750 Systems User's Guide

  Hardware Requirements

  Software Requirements

  Configuring the Host System

  Configuring the Client System

  Managing the Host System Remotely

  Configuring Special Key Functions

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 or RAID settings.

You can also connect the client system to a port concentrator that can access numerous host systems using a shared modem. After logging into the port concentrator, you can select a host system to manage using console redirection.

This section describes the most basic connection possible: connecting systems using a null-modem serial cable, which directly connects the serial ports on two systems.

Hardware Requirements

l  An available serial (COM) port on the host system

l  An available serial (COM) port on a client system

This port must not conflict with any other ports on the client system.

l  A null-modem serial cable to connect the host system to the client system

Software Requirements

l  VT 100/220 or ANSI terminal emulation with a window size of 80 x 25 characters

l  9600, 19.2 K, 57.6 K, or 115.2 K bps using serial (COM) ports

l  Ability to create keyboard command macros (recommended)

All versions of the Microsoft Windows operating system include Hilgraeve's HyperTerminal terminal emulation software. However, the included version does not provide many functions required during console redirection. Either upgrade to HyperTerminal Private Edition 6.1 or later, or select new terminal emulation  software.

Configuring the Host System

Configure console redirection on the host (local) system through the System Setup program (see "Using the System Setup Program"). The Console Redirection screen allows you to enable or disable the console redirection feature, select the remote terminal type, and enable or disable console redirection after booting.

Configuring the Client System

NOTE: Your system's optional remote access controller (RAC) uses a different implementation of console redirection. For information on console redirection using a remote access card, see the remote access card documentation.

After configuring the host system, configure the ports and terminal settings for the client (remote) system.

Configuring the Serial Port

1.  Click the Start button, point to Programs Accessories Communications, and then click HyperTerminal.

2.  Enter a name for the new connection, select an icon, and then click OK.

3.  From the Connect to dropdown menu, select an available COM port, and then click OK.

After you select an available COM port, the COM port properties window appears.

4.  Configure the port with the following settings:

l  Set Bits per second.

Console redirection supports only 9600, 19.2 K, 57.6 K, or 115.2 K bps.

l  Set Data bits to 8.

l  Set Parity to None.

l  Set Stop bits to 1.

l  Set Flow control to Hardware.

5.  Click OK.

Configuring the Terminal Settings

1.  In HyperTerminal, click File, click Properties, and then click the Settings tab.

2.  Ensure that the Function, arrow, and Ctrl keys act as field is set to Terminal Keys.

3.  Ensure that the Backspace key sends field is set to Ctrl+H.

4.  Change the Emulation setting from Auto detect to ANSI or VT 100/220.

Ensure that this setting is the same as the setting you selected for the Console Redirection option on the host system.

5.  Click Terminal Setup.

A setting for the number of rows and columns appears.

6.  Change the number of rows from 24 to 25 and leave the number of columns at 80.

If you do not have these settings, you must upgrade your terminal emulation software.

7.  Click OK twice.

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.

2.  When the host system begins to boot, use console redirection to:

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.

l  Enter the System Setup program

l  Enter the SCSI setup menus

l  Update firmware and BIOS (flash the system)

l  Run utilities on the utility partition

Configuring Special Key Functions

Console redirection uses ANSI or VT 100/220 terminal emulation, which is limited to basic ASCII characters. Function keys, arrow keys, and control keys are not available in the ASCII character set, and most utilities require function keys and control keys for ordinary operations. However, you can emulate a function key or control key using a special key sequence, called an escape sequence.

An escape sequence starts with an escape character. You can enter this character in different ways, depending on the requirements of your terminal emulation software. For example, 0x1b and each represent the escape character. In HyperTerminal, you can create macros by selecting Key Macros

from the View menu. You can assign a macro to almost any key for almost any key combination. Create a macro to represent each function key.

Table B-1 lists the escape sequences that represent a special key or function.

 Table B-1. Supported Escape Sequences 

NOTE: To run utilities on the host system's utility partition, you must have created the utility partition using Dell OpenManage Server Assistant  version 6.3.1 or later.

NOTE: When creating macros in HyperTerminal, press before to signify that you are sending an escape sequence rather than escaping out of the dialog box. If you do not have this function, you must upgrade HyperTerminal.

NOTE: Escape-sequence key combinations listed in Table B-1 are case-sensitive. For example, to generate the character

you must press

Power Protection Devices

Certain devices protect your system from the effects of problems such as power surges and power failures.

l PDU Uses circuit breakers to ensure that the AC current load does not exceed the PDU's rating.

l Surge protector Prevents voltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. Surge protectors do not provide protection from brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.

l Line conditioner Maintains a system's AC power source voltage at a moderately constant level and provides protection from brownouts, but does not protect against a complete power loss.

l UPS Uses battery power to keep the system running when AC power is unavailable. The battery is charged by AC power while it is available so that after AC power is lost, the battery can provide power to the system for a limited amount of timefrom 15 minutes to approximately an hour. A UPS that provides only 5 minutes of battery power allows you to shut down the system. Use surge protectors and PDUs with all universal power supplies, and ensure that the UPS is UL-safety approved.

If you forget your password, you cannot operate your system or change settings in the System Setup program until a trained service technician changes the password jumper setting to disable the passwords, and erases the existing passwords. This procedure is described in the Installation and Troubleshooting Guide.

Using the System Password

After a system password is assigned, only those who know the password have full use of the system. When the System Password option is set to Enabled, the system prompts you for the system password after the system starts.

Assigning a System Password

Before you assign a system password, enter the System Setup program and check the System Password option.

When a system password is assigned, the setting shown for the System Password option is Enabled. If the setting shown for the Password Status is Unlocked, you can change the system password. If the Password Status option is Locked, you cannot change the system password. When the system password feature is disabled by a jumper setting, the system password is Disabled, and you cannot change or enter a new system password.

When a system password is not assigned and the password jumper on the system board is in the enabled (default) position, the setting shown for the System Password option is Not Enabled and the Password Status field is Unlocked. To assign a system password:

1. Verify that the Password Status option is set to Unlocked.

2. Highlight the System Password option and press .

3. Type your new system password.

You can use up to 32 characters in your password.

As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.

The password assignment is not case-sensitive. However, certain key combinations are not valid. If you enter one of these combinations, the system beeps. To erase a character when entering your password, press or the left-arrow key.

4. Press .

5. To confirm your password, type it a second time and press .

The setting shown for the System Password changes to Enabled. Exit the System Setup program and begin using your system.

6. Either reboot your system now for your password protection to take effect or continue working.

Using Your System Password to Secure Your System

NOTICE: The password features provide a basic level of security for the data on your system. If your data requires more security, use additional forms of protection, such as data encryption programs.

NOTICE: Anyone can access the data stored on your system if you leave the system running and unattended without having a system password assigned or if you leave your system unlocked so that someone can disable the password by changing a jumper setting.

NOTE: To escape from the field without assigning a system password, press to move to another field, or press at any time prior to completing step 5.

NOTE: Password protection does not take effect until you reboot the system.

When the Password Status option is set to Unlocked, you have the option to leave the password security enabled or to disable the password security.

To leave the password security enabled:

1. Turn on or reboot your system by pressing .

2. Press .

3. Type your password and press .

To disable the password security:

1. Turn on or reboot your system by pressing .

2. Press .

When the Password Status option is set to Locked wheneveryou turn on your system or reboot your system by pressing , type your password and press at the prompt.

After you type the correct system password and press , your system operates as usual.

If an incorrect system password is entered, the system displays a message and prompts you to re-enter your password. You have three attempts to enter the correct password. After the third unsuccessful attempt, the system displays an error message showing the number of unsuccessful attempts and that the system has halted and will shut down. This message can alert you to an unauthorized person attempting to use your system.

Even after you shut down and restart the system, the error message continues to be displayed until the correct password is entered.

Deleting or Changing an Existing System Password

1. When prompted, press to disable the existing system password.

If you are asked to enter your setup password, contact your network administrator.

2. Enter the System Setup program by pressing during POST.

3. Select the System Security screen field to verify that the Password Status option is set to Unlocked.

4. When prompted, type the system password.

5. Confirm that Not Enabled is displayed for the System Password option.

If Not Enabled is displayed for the System Password option, the system password has been deleted. If Enabled is displayed for the System Password option, press the key combination to restart the system, and then repeat steps 2 through 5.

Using the Setup Password

Assigning a Setup Password

You can assign (or change) a setup password only when the Setup Password option is set to Not Enabled. To assign a setup password, highlight the Setup Password option and press the <+> or <> key. The system prompts you to enter and verify the password. If a character is illegal for password use, the system beeps.

NOTE: If you have assigned a setup password (see "Using the Setup Password"), the system accepts your setup password as an alternate system password.

NOTE: You can use the Password Status option in conjunction with the System Password and Setup Password options to further protect your system from unauthorized changes.

NOTE: The setup password can be the same as the system password. If the two passwords are different, the setup password can be used as an alternate system password. However, the system password cannot be used in place of the setup password.

You can use up to 32 characters in your password.

As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.

The password assignment is not case-sensitive. However, certain key combinations are not valid. If you enter one of these combinations, the system beeps. To erase a character when entering your password, press or the left-arrow key.

After you verify the password, the Setup Password setting changes to Enabled. The next time you enter the System Setup program, the system prompts you for the setup password.

A change to the Setup Password option becomes effective immediately (restarting the system is not required).

Operating With a Setup Password Enabled

If Setup Password is set to Enabled, you must enter the correct setup password before you can modify most of the System Setup options. When you start the System Setup program, the program prompts you to enter a password.

If you do not enter the correct password in three attempts, the system lets you view, but not modify, the System Setup screenswith the following exception: If System Password is not set to Enabled and is not locked through the Password Status option, you can assign a system password (however, you cannot disable or change an existing system password).

Deleting or Changing an Existing Setup Password

1. Enter the System Setup program and select the System Security option.

2. Highlight the Setup Password option, press to access the setup password window, and press twice to clear the existing setup password.
