Embedded Lights Out Manager Overview |
This chapter serves as an overview of the capabilities of the Sun Fire X4150 and X4450 server Embedded Lights Out Manager (ELOM), and contains the following sections:
The ELOM provides a dedicated system of hardware and supporting software that enables you to manage your server independent of an operating system, and in low-power situations. ELOM is composed of four components:
You can access the ELOM using a web browser, secure shell (SSH), or via the Sun Fire server’s serial port. Your server’s default network setting is configured as DHCP for easy access via a web browser or SSH, and the ELOM output is directed by default to the serial port.
The following table shows common tasks and the management interfaces used to perform each task.
Sun has configured the SP controller and SP firmware on your server to use the most common default settings. It is unlikely that you will need to change any of these defaults.
The ELOM is shipped with one preconfigured administrator account:
User name: root
Password: changeme
The preconfigured administrator account, root, is the default account. It cannot be deleted or modified. You can only change the password for the root account. This default account contains administrator privileges (read and write access) to all service processor features and commands. For security reasons you should change the root password and create an alternate user account that also has administrator privileges. To change a user password or to create a new user, see Chapter 4.
If you’ve changed the root password, but have not created an alternate account, and the new root password is lost or forgotten, you will have to reset the SP to return the ELOM to its default settings. For information about how to do this, seeResetting the Service Processor.
The LEDs on the front and rear panel of your server allow you to manage the server at a rudimentary level. The LEDs are helpful for indicating when a problem has occurred, and you can use these LEDs in combination with the internal fault indicator LEDs and buttons to troubleshoot and repair component failure issues. However, using the ELOM it is possible not only to troubleshoot component failure issues, but also to configure, manage, and maintain the server remotely and to implement an effective preventative maintenance program. Using the ELOM as part of a regular maintenance regimen allows you to take a proactive approach to server repair. This can improve system performance and minimize downtime.
For information about the Indicator and Fault LEDs, see the server service manual.
For information about managing, maintaining, and configuring your server, see Chapter 4 of this guide.
