Setting Up the Sun Fire X2250 Server Hardware

This chapter describes how to set up the Sun Fire X2250 server hardware. It includes the following topics:

Safety and Compliance Information

Refer to the following documents for safety information regarding the Sun Fire X2250 server:


Planning the Installation Process

Use the flowchart in FIGURE 1-1 to assist you with the server installation process.

FIGURE 1-1 Sun Fire X2250 Server Installation Process

Flowchart showing the installation process that is documented in this guide.

Package Contents Inventory

Carefully unpack all server components from the packing cartons. The following items should be packaged with the Sun Fire X2250 server:

The optional power cable, keyboard, and mouse are packaged separately from the other items.

Installing the Server Into a Rack With Optional Slide Rails

The service label on the top cover of the Sun Fire X2250 server contains instructions for installing your server into a four-post rack using the orderable slide-rail and cable management arm options. Detailed instructions can also be found online in the Sun Fire X2250 Server Service Manual (820-4593) at the following URL:


The slide rails for the Sun Fire X2250 server are compatible with a wide range of equipment racks that meet the following standards:

caution icon Caution - Always load equipment into a rack from the bottom up so that the rack will not become top-heavy and tip over. Deploy your rack’s anti-tilt bar to prevent the rack from tipping during equipment installation.

caution icon Caution - Ensure that the temperature in the rack does not exceed the server’s maximum ambient rated temperatures. Consider the total airflow requirements of all equipment installed in the rack, to ensure that the equipment is operated within its specified temperature range.

Connecting the Cables

See FIGURE 1-2 and TABLE 1-1 for the locations of the connectors.

procedure icon  To Connect the Cables

Connect the server and external devices as follows:

1. Connect a serial null modem cable to the serial port.

The default serial port speed is 9600 baud with no flow control.

2. Connect Ethernet cables to the RJ-45 LAN Gigabit Ethernet connectors as needed (see FIGURE 1-2).

Note the following guidelines regarding the Ethernet (LAN) ports:

See Setting Up the Sun Fire X2250 Server Software for additional information about setting up the service processor for remote system management.

3. Connect any additional external devices to the server’s other connectors.

Powering On and Off the Server

You only need to apply standby power to the server at this point so that you can perform initial configuration of the service processor. Procedures for powering on to main power mode and for shutting down from main power mode are also included in this section, for your reference.

procedure icon  To Apply Standby Power for Initial Service Processor Configuration

Use this procedure to apply standby power to the service processor (SP) before initial configuration.

caution icon Caution - Do not operate the server without all fans, component heatsinks, air baffles, and the cover installed. Severe damage to server components can occur if operated without adequate cooling mechanisms.

1. Connect a grounded AC power cord to the AC power connector on the back panel of the server and to a grounded AC power outlet.

In standby power mode, the Power/OK LED on the front panel flashes, indicating that the SP is receiving power. See FIGURE 1-3 and TABLE 1-2.

2. Continue with initial software setup tasks, as described in Chapter 2.

Note - At this point, standby power is supplied only to the service processor and power supply fans. You can proceed to Chapter 2 of this guide to begin initial configuration. Do not apply main power to the rest of the server until you are ready to install a platform operating system.

procedure icon  To Power On Main Power Mode

To power on main power for all server components:

1. Verify that the power cord has been connected and that standby power is on.

In standby power mode, the Power/OK LED on the front panel flashes. See FIGURE 1-3.

2. Use a non-metallic stylus to press and release the recessed Power button on the server front panel.

When main power is applied to the full server, the Power/OK LED next to the Power button lights and remains lit.

Note - The first time the server powers on, the power-on self-test (POST) can take up to a minute to complete.

procedure icon  To Power Off Main Power Mode

To power off the server from main power mode, use one of the following two methods:

caution icon Caution - To completely power off the server, you must disconnect the AC power cords from the back panel of the server.

Setup Troubleshooting and Support

This section contains information to help you troubleshoot minor server problems.
It includes the following topics:

Troubleshooting the Sun Fire X2250 Server Setup

If you experience problems while setting up your server, refer to the troubleshooting information in TABLE 1-3.

TABLE 1-3 Troubleshooting Procedures


Possible Solution

Server powers on, but the monitor does not.

  • Is the Power button for the monitor turned on?
  • Is the monitor power cord connected to a wall outlet?
  • Does the wall outlet have power? Test by plugging in another device.

CD or DVD does not eject from the media tray when you press the Eject button.

  • Move the mouse or press any key on the keyboard. The drive might be in low power mode.
  • Use the utility software installed on your server to eject the CD.
  • Ensure that the media in the device is not in use and is not mounted by the operating system.

No video is displayed on the monitor screen.

  • Is the monitor cable attached to the video connector?
  • Does the monitor work when connected to another system?
  • If you have another monitor, does it work when connected to the original system?
  • If, after POST and BIOS complete, you no longer see video output on your monitor and only see a flashing cursor, check the configuration of the operating system to determine whether it is configured to redirect its output exclusively over the serial line.

Server does not power on when the front panel Power button is pressed.

Keep notes on the following situations in case you need to call Sun service:

  • Is the Power/OK LED illuminated on the front of the system? (Ensure that the power cord is connected to the system and to a grounded power receptacle.)
  • Does the wall outlet have power? Test by plugging in another device.
  • Does the monitor sync within five minutes after power on? (The green LED on the monitor stops flashing and remains illuminated.)

Keyboard or mouse does not respond to actions.

  • Verify that the mouse and keyboard cables are connected to the on-board USB 2.0 connectors on the server.
  • Verify that the server is powered on and the front Power/OK LED is illuminated.

Server appears to be in low power mode, but the Power/OK LED does not blink.

The Power/OK LED only blinks when all server components are in low power mode. A tape drive might be connected to your server. Because tape drives do not enter low power mode, the Power/OK LED does not blink.

Server is hung or frozen: No response from mouse or keyboard or any application.

Try to access your system from a different server on the network:

  1. On another system, type ping IP_address_of_X2250
  2. If a response is returned, then try logging in to the Sun Fire X2250 server using either telnet, ssh or rlogin.
  3. If you successfully log in, list the running processes using the ps command.
  4. Kill any processes that appear unresponsive or should not be running, by using the kill process_ID command.
  5. Check the responsiveness of the Sun Fire X2250 server after each process is killed.

If the above procedure does not work, power cycle the server:

  1. Press the Power button to power off the server and wait 20 to 30 seconds.
  2. Press the Power button again to power on the system.

Note - For additional troubleshooting information, see the Sun Fire X2250 Server Service Manual (820-4593).
