Chapter 5. Configuration requirements for the blade serverThis chapter contains the configuration tasks that you must perform so that you canrun Serial Over LAN (SOL) sessions on the blade server and use the IBMBladeCenter management-module command-line interface. This chapter alsodescribes other configuration requirements for the blade server.SOL provides a means to manage servers remotely by using a command-lineinterface (CLI) over a Telnet or Secure Shell (SSH) connection. SOL is required tomanage servers that do not have KVM support, such as the JS20 Type 8842 bladeserver.SOL provides console redirection for both BIOS and the blade server operatingsystem. The SOL feature redirects server serial-connection data over a LAN withoutthe need for special cabling. The SOL connection enables blade servers to bemanaged from any remote location with Internet access. The advantages of SOLinclude:v Remote administration without keyboard, video, or mouse (headless servers)v Reduced cabling and no need for a serial concentratorv Standard Telnet interface that eliminates the need for special client softwareAfter you install the blade server in the BladeCenter unit, the blade server isautomatically configured. The Broadcom Ethernet controller device driver is installedafter you install the operating system. The blade server is automaticallyreconfigured after you install software or hardware. IBM will periodically makefirmware updates available for the blade server. Before you continue, you can makesure that the blade server has the latest version of firmware code. For additionalinformation, see “Updating the firmware code for the blade server and the serviceprocessor” on page 40.Since the firmware code in the blade server uses auto-configuration, additionalblade-server configuration programs are not required for the blade server. However,if you have attached other devices to the blade server or the BladeCenter unit, youmust configure those devices as described in the applicable documentation thatcomes with those devices or the BladeCenter unit. You do not have to set anypasswords to use the blade server. If you change the battery or replace thesystem-board assembly, you must reset the date and time through your operatingsystem.For information about setting up your network configuration for remotemanagement, see the IBM BladeCenter Planning and Installation Guide or the IBMBladeCenter T Planning and Installation Guide located at http://www.ibm.com/support on the World Wide Web.Complete the following steps to locate the most recent version of BladeCenterdocumentation, including the IBM BladeCenter Planning and Installation Guide orthe IBM BladeCenter T Planning and Installation Guide:1.
