  Using Console Redirection Dell PowerEdge 1800 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 "Console Redirection Screen" in "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

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 drop-down menu, select an available COM port, and then click OK.

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

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.

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.

  l 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:

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.

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.

 Table B-1. Supported Escape Sequences 

After creating macros for the keys listed in Table B-1, press on the client system's keyboard during terminal emulation to send the escape sequence

to the host system. The host system then interprets the sequence as .

Additional escape sequences may be required by certain utilities or functions on the host system. Create macros for the additional sequences listed in Table B- 2.

.

 Table B-2. Additional Escape Sequences

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. They do not protect against 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 5 minutes to approximately an hour. A UPS that provides only 5 minutes of battery power allows you to save your files and to shut down the system. Use surge protectors and PDUs with all universal

NOTE: DVD devices are data only.

NOTE: Slot 1 accepts half-length PCI cards. Slot 6 accepts full-length unless SCSI is used (because of the SCSI cabling). All other slots accept full- length PCI cards.
