Configuring the DRAC 4 to Use a Serial or Telnet Text Console

The DRAC 4 provides serial and telnet command interfaces designed to perform all of the configuration and systems management functions using the DRAC 4 Web-based interface or racadm CLI.

The following section provides information about the serial/telnet text console features, and explains how to set up your system so you can perform systems management actions through a serial/telnet console.

Serial and Telnet Console Features

The DRAC 4 supports the following serial and telnet console redirection features:

•One serial client connection and up to four telnet client connections at one time

NOTE: When a telnet login is invalid, a single session is counted toward the maximum of four sessions for approximately one minute after the invalid login attempt. If there are already three valid sessions, this invalid session will prevent further login attempts for that minute.

•Access to the managed system consoles through the system serial port and through the

DRAC 4 NIC

•Serial/telnet console commands that allow you to power-on, power-off, power-cycle, reset, view logs, view sensor status, or configure the DRAC 4

•Serial/telnet console support for the racadm command, which is useful for scripting

•Command line editing and history

•The connect com2 serial command to connect, view, and interact with the managed system text console that is being output through a serial port (including BIOS and the operating system)

NOTE: If you are running Red Hat® Enterprise Linux on the managed system, the connect com2 serial command provides a true Red Hat Enterprise Linux console stream interface.
