Powering On the System
This chapter includes instructions for booting the Sun Fire T2000 system and for enabling the system controller network management port.
The following topics are discussed:
Tip - The serial terminal or a terminal emulator should be connected before you connect the power cables, or you will not see the system messages. The server goes into standby mode and the ALOM-CMT system controller initializes as soon as the AC power cables are connected to the power source.
Note - If you are not logged in, ALOM-CMT times out after 60 seconds and reverts to the system console. For more information, refer to the Sun Fire T2000 Server Advanced Lights Out Management (ALOM) Guide.
The system controller runs on the 3.3v standby voltage. As soon as AC power is connected to the system, the system controller powers on, runs diagnostics, and initializes the ALOM-CMT firmware.
1. If you have not already done so, connect a terminal or a terminal emulator (PC or workstation) to the SC serial management port. Configure the terminal or terminal emulator with these settings:
Note - When you power on the server for the first time and you do not have a terminal or terminal emulator (PC or workstation) connected to the SC serial management port, you will not see system messages. The display times out and disappears after about 60 seconds.
2. Turn on the terminal or terminal emulator.
3. Connect the AC power cables to Power Supply 0 and Power Supply 1, and watch the terminal for system messages.
After the system controller boots, the system controller login prompt is displayed on the serial console. The following example shows a partial output from the system controller boot sequence leading to the login prompt.
The system controller network management port is not operational until you configure network settings for the system controller. Configure the system controller in this order:
1. After the system controller boots, access the ALOM-CMT command line interface through the serial management port. See To Log Into the System Controller Using the Serial Management Port.
2. Configure the system controller. See To Configure the System Controller Network Management Port.
3. Enable the new values by resetting the system controller. See To Reset the System Controller.
You can now use the SP network management port at any time to access the system controller. See To Log Into the System Controller Using the Network Management Port.
If you are powering on the system for the first time after installation, use the system controller serial port to power on the system and run POST. See To Log Into the System Controller Using the Serial Management Port.
If the network management port has already been configured, you can use it instead of the serial management port. See To Log Into the System Controller Using the Network Management Port.
After the system controller boots you can access the ALOM-CMT command line interface to configure and manage the system.
The sc prompt is displayed at the first time the system controller is booted. The default configuration provides an ALOM-CMT user account called admin. There is no default password, so you must create a password using the system controller (sc) password command.
1. If this is the first time the system has been powered on, use the password command to set the admin password.
After the admin password has been set, on subsequent reboots, the sc login prompt is displayed.
2. Enter admin for the login name followed by your password.
To access the system controller using the network for the first time, you must first configure the SC network management port through the SC serial management port.
Set these network parameters according to the specific details of your network configuration:
To configure these parameters you must use the setsc command. The usage is:
1. Set the netmask for the system controller.
This example uses 255.255.255.0 to set the netmask. Your network environment subnet might require a different netmask. Use a netmask number most appropriate to your environment.
2. Set the IP address for the system controller.
3. Set the IP address for the system controller gateway.
4. Set the if_network parameter to true.
5. Use the showsc command to verify that the parameters were set correctly.
The showsc command displays all the configuration parameters and their values, as listed in TABLE 3-1.
After all of the configuration parameters are set, you must reset the system controller for the new values to take affect.
Issue the resetsc command.
You are prompted to confirm that you want to reset the system controller. Reply y when prompted.
The system controller resets, runs diagnostics, and returns to the login prompt.
Note - You must configure the system controller parameters shown in To Configure the System Controller Network Management Port before you can use the network management port.
1. Open a telnet session and connect to the system controller by specifying its network address.
2. Login as admin using the password you previously set.
Powering on the system requires you to use the poweron command at the SC console.
To initiate the power-on sequence, issue the poweron command.
You will see an sc> alert message on the system console. This indicates that the system has reset.
Output from POST, OpenBoot, and the Solaris OS is displayed in the system console using the network console on the system controller.
Execute the console command, and use the -f option to force the console to be attached to your session.
Multiple users can be connected to the console, but only one can be attached.
After you issue the poweron command, the CPU and memory controllers initialize, and eventually OpenBoot initializes. After a number of system messages, you will see the ok prompt.
The example output below is a small section of the complete output.

To understand the various devices and their path names as represented in the OpenBoot PROM device tree, refer to TABLE 3-2. The table identifies each of the devices, their full path name and their location or NAC name used to identify their physical location.
The Solaris OS is preinstalled on Sun Fire T2000 servers on the disk in slot 0. The Solaris OS is not configured (that is, the sys-unconfig command was run in the factory). If you boot the system from this disk, you will be prompted to configure the Solaris OS for your environment.
1. At the ok prompt, boot from the disk that contains the Solaris OS.
If you know which disk to boot from, skip Step a and perform Step 2.
a. If you need to determine which disk to boot from, issue the show-disks command at the ok prompt to see the path to the configured disks.
2. Type the boot command at the ok prompt.
Use the value from Step 1 to construct the boot command. You will need to append the target to the disk path. In the following example, the system is being booted from disk 0 (zero), so @0,0 is appended to the disk path.
If it is necessary to reset the system, use the uadmin command.
To simply reset the system, it is not necessary to power the system off and on.
If a simple reset does not clear a system problem, you can power the system off and on with this procedure.
1. Shut down the Solaris OS.
At the Solaris OS prompt, issue the uadmin command to halt the Solaris OS and to return to the ok prompt.
2. Switch from the system console prompt to the SC console prompt by issuing the #. escape sequence.
3. Using the SC console, issue the poweroff command.
4. Issue the poweron command.
5. Reconnect to the system console using the console command.
The systems displays various messages, followed by the ok prompt.
