Connecting to the ELOM

This chapter details the ways to connect and communicate with your Sun Blade X6250 server module.



Note - You must have already installed your server and determined the IP address of the service processor. Information about installing the server and determining the IP address of the service processor is available in the Sun Blade X6250 Server Module Installation Guide.



Connection Methods

There are two ways to connect to the Embedded Lights Out Manager (ELOM) in your server:

Connecting Using Ethernet

Ethernet connectivity provides full access to both the ELOM command-line interface (CLI) and the ELOM web GUI. Both options allow you to manage and maintain the server. This section contains the following two connection procedures:



Note - You will need the IP address of your ELOM, which you obtained during the setup and installation of your server module (see the Sun Blade X6250 Server Module Installation Guide).



procedure icon  To Connect to the CLI

Be sure that you have connected a LAN to the NET MGT 0 port on the chassis.

1. Start your SSH client.

When you first access the CLI, you will need to use the preconfigured user name and password:

2. To log in to the ELOM, enter the following command:

$ ssh username@ipaddress

username An account user name.
ipaddress The IP address of the ELOM.

A password prompt appears.

3. When prompted, enter the password.

The CLI prompt appears:

->

For information about managing the server using the CLI, see Chapter 6.

To Log out of the CLI:

-> exit


procedure icon  To Connect to the Web GUI

Be sure that you have connected a LAN to the NET MGT 0 port on the chassis.

1. To log in to the web GUI, enter the IP address of the ELOM into your browser.

The login screen appears.

2. Enter your user name and password.

When you first access the web GUI, it prompts you for the default user name and password:

The default user name and password are in lowercase characters.

3. Click Log In.

Chapter 3 shows how to use the web GUI.

To Log Out of the Web GUI:

single-step bullet  Click Log Out at the top right of the web GUI screen.

The login screen appears.

Connecting Through the Chassis Manager Module

The chassis serial connector connects to the Chassis Management Module’s (CMM) Integrated Lights Out Manager (ILOM). You can connect to the server module ELOM via this serial connection using a RJ-45 cable and a terminal (or a PC running terminal emulation software). Once connected, you can use the command-line interface (CLI) to manage, maintain, and configure the server.


procedure icon  To Connect Through the Chassis Manager Module

1. Verify that your terminal, laptop, or terminal server is operational.

2. Configure the terminal device or the terminal emulation software to use the following settings:

3. Connect a serial cable from the serial port on the CMM to the terminal device.

Refer to the chassis documentation for the location of the chassis serial port.

4. Press Enter on the terminal device.

This action establishes the connection between the terminal device and the CMM ILOM.

The CMM ILOM displays its login prompt:

SUNCMMnnnnnnnnnn login:

The first string in the prompt is the default host name. It consists of the prefix SUNCMM and the CMM ILOM’s MAC address. The MAC address for each service processor is unique.

5. Log in to the CLI:

When you first access the CLI, you will need to use the preconfigured user name and password:

Once you have successfully logged in, the CMM ILOM displays its default command prompt:

->

You are now connected to the CMM ILOM CLI.

6. Navigate to the server module ELOM by entering this command:

cd /CH/BLn/SP/cli

n The position number of the server module in the chassis. Use FIGURE 2-1 to assist you in determining the server module number, and to understand the relationship between the CMM and different server module service processors.

7. Enter the command start.

The following prompt appears:


  Enter Y to continue or N to cancel.

8. Enter Y to continue.

If you enter N, the server module will return you to the CMM CLI prompt.

9. Enter the password when prompted.

Supply the password for root. The preconfigured default is changeme.

The server module ELOM prompt appears.
For information about managing and maintaining the server module, see Chapter 6.

10. When you are finished, enter exit at the ELOM CLI prompt.

The CMM CLI prompt appears.

The following display shows an example of the login screen:


 -> cd /CH/BL2/SP/cli
/CH/BL2/SP/cli
 
-> start
Are you sure you want to start /CH/BL2/SP/cli (y/n)? y
Password:         Enter the password to the server module ILOM.
