Hardware Information

This section provides information about the system hardware.

The server module is installed in a Sun Blade 6000 Modular System. It consists of a chassis with fans, power supplies some hardware support, and space for up to nine server modules. The server modules are installed in the modular system chassis.

The chassis has its own ILOM, called a Chassis Management Module Integrateed Lights Out Manager (CMM ILOM). It is described in the Integrated Lights Out Manager (ILOM) Administration Guide For Sun Blade 6000 Modular System Chassis, 820-0052.

Server Locator Indicator

The Server Locator Indicators (also called the Locate LED buttons) are small lights that you turn on to help you identify a specific server among many in a data center. One light is positioned on the front of the server in the upper-left corner, and the other light is on the back of the server in the upper-center section.

Connecting to ILOM

This section describes how to connect to the ILOM located in the Sun Blade X6220 server module.



Note - The Sun Blade 6000 Modular System chassis has its own ILOM, called a CMM ILOM, which is a separate entity from the server module ILOM. It is described in the Integrated Lights Out Manager (ILOM) Administration Guide For The Sun Blade 6000 Modular System, 820-0052.



You can connect to the ILOM on your server module using one of the following methods:



Note - The CMM ILOM in the chassis has an Ethernet switch that supports connections to the server modules and their ILOMs. To use this connection, you must be connected to the same subnet as the ILOM, and you must know the server module ILOM's Ethernet address.



The following sections describe each of these methods. FIGURE 1 shows the connections.

FIGURE 1 ILOM Connection Options


Graphic showing Gemini rear panel, including port locations.

Option 1 - Connecting to ILOM Through the Chassis Ethernet Port

Normally, you connect to the ILOM through the Ethernet. When the server module is installed in the chassis, its ILOM is automatically accessible on the same subnet as the CMM ILOM.

If you do not know the ILOM's IP address, find it as described in Finding the ILOM's IP Address.

You can connect to the ILOM using SSH to connect to the command line interface (CLI), or using a browser to connect to the webGUI.

Finding the ILOM's IP Address

To find the ILOM's IP address:

1. Log in to the CMM.

See the Integrated Lights Out Manager (ILOM) Administration Guide For the Sun Blade 6000 Modular System, 820-0052 for details.

2. Type the command:

show /CH/BLn/SP/network

where n is the server module number.

3. The CLI displays infomation about the server module, including its IP address.

For example:


-> show /CH/BL0/SP/network
 
 /CH/BLN/SP/network
    Targets:
 
    Properties:
        type = Network Configuration
        commitpending = (Cannot show property)
        ipaddress = IPaddress
        ipdiscovery = dhcp
        ipgateway = IPgateway
        ipnetmask = 255.255.252.0
        macaddress = Macaddress
        pendingipaddress = Ipaddress
        pendingipdiscovery = dhcp
        pendingipgateway = IPgateway
        pendingipnetmask = 255.255.252.0
 
    Commands:
        cd
        set
        show
 
-> 

Connecting to the CLI

1. Start your SSH client.

2. To log in to the ILOM, type:

$ ssh root@ipaddress

where ipaddress is the address of the ILOM.

3. Type your password when prompted.

The default is changeme.

The CLI command prompt appears.

Connecting to the WebGUI

1. Type the IP address of the ILOM into your web browser.

The login screen appears.

2. Type your user name and password.

When you first try to access the WebGUI, it prompts you to type the default user name and password. The default user name and password are:

The default user name and password are in lowercase characters.

3. Click Log In.

The WebGUI appears.

4. To log out of the WebGUI, click the Log Out button.

The log out screen appears.

Do not use the Log Out button in your web browser to log out from the WebGUI.

Option 2 - Connecting to ILOM Through the Chassis Serial Connector

The chassis serial connector connects to the chassis CMM ILOM. The CMM ILOM provides a command to connect to the server module ILOM(s).

5. Connect a serial cable from the serial port on the chassis to a terminal device.

The terminal device can be an actual terminal, a laptop running a terminal emulator, or a terminal server. It must be set to the following:

The cable requires the following pin assignments.

The first string in the prompt is the default host name. It consists of the prefix SUNSP and the CMM ILOM's MAC address.

7. Log in to the CMM ILOM.

The default user is root and the default password is changeme.

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

->

8. Navigate to /CH/BLn/SP/cli.

Where n is 0 through 9 for server modules 0 through 9 respectively.

9. Enter the the command start

A prompt appears.

10. Enter y to continue or n to cancel.

If you entered y, the server module ILOM prompts for its password.



Note - The CMM ILOM logs on to the server module ILOM using the username in /CH/BLn/SP/cli/user (where n is the server module number). The default is root.



11. Enter the ILOM password.

The server module ILOM's CLI interface appears. You are now connected to the server module ILOM.

12. When you are done, type exit.

The server module ILOM exits and the CMM ILOM CLI prompt appears.

The following display shows an example:


 -> cd /CH/BL2/SP/cli
/CH/BL2/SP/cli
 
-> start
Are you sure you want to start /CH/BL2/SP/cli (y/n)? y

Option 3 - Connecting to ILOM Through a Dongle Cable

A dongle cable allows you to connect a terminal directly to the ILOM. FIGURE 2 shows a dongle cable connected to a server module.



Note - If the terminal requires an RJ45 connector, you can use the RJ45 to DB9 adaptor shipped with the chassis.



1. Connect a dongle cable directly to the server module.

2. Connect a terminal or terminal emulator to the DB9 connector on the dongle cable. The dongle cable is labelled "2" in FIGURE 2.

The CLI login prompt appears.

3. Enter the the user name and password when prompted.

The default user is root and the default password is changeme.

The CLI prompt appears.

FIGURE 2 shows the the dongle cable.

Resetting the Service Processor and BIOS Passwords

A procedure in the Sun Blade X6220 Server Module Service Manual, 820-0046 allows you to reset the Service Processor and BIOS passwords.


Temperature, Voltage, and Fan Sensors

The server module includes a number of sensors that generate entries in the system event log (SEL) when the sensor crosses a threshold. Many of these readings are used to adjust the fan speeds and perform other actions, such as illuminating LEDs and powering off the chassis.



Note - Fan and power supply sensors represent fans and power supplies in the chassis, not in the server module.



These sensors can also be configured to generate IPMI PET traps as, described in the Integrated Lights Out Manager (ILOM) Administration Guide 820-0280.

This section describes the sensors and provides details about their operation.



Caution - Do not use any interface other than the ILOM CLI or WebGUI to alter the state or configuration of any sensor or LED. Doing so could void your warranty.
