1.4 Powering On and Powering 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.

1.4.1 Applying Standby Power for Initial Service Processor Configuration

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

configuration.

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

without adequate cooling mechanisms.

1. Connect grounded AC power cords to the AC power connector on the back

panel of the server and to a grounded AC power outlet.

operated

Note – At this point, standby power is supplied only to the service processor and power

supply fans. Do not apply main power to the rest of the server until you are ready to install a platform operating system.

2. Continue with initial software setup tasks, as described in Sun Fire X2250 Server

Installation Guide (820-4591).

Chapter 1 Sun Fire X2250 Server Overview 1-7

1.4.2 Powering 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 1-1.

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.

1.4.3 Shutting Down Main Power Mode

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

■ Graceful shutdown: Use a non-metallic stylus to press and release the Power

button on the front panel. This causes Advanced Configuration and Power Interface (ACPI) enabled operating systems to perform an orderly shutdown of the operating system. Servers not running ACPI-enabled operating systems will shut down to standby power mode immediately.

■ Emergency shutdown: Press and hold the Power button for four seconds to force

the main power off and enter standby power mode. When the main power is off, the Power/OK LED on the front panel will begin flashing, indicating that the server is in standby power mode.

Caution – To completely power off the server, you must disconnect the AC power cords

from the back panel of the server.

1-8 Sun Fire X2250 Server Service Manual • April 2009

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

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

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.

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,orrlogin.

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.

Problem Possible solution

No video is displayed on the monitor screen.

Check the following:

• Is the monitor cable connected 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 if it is configured to redirect its output exclusively over the serial line.

External device is not working.

• Check the documentation that came with the device to see if any device drivers must be installed.

• Verify that the cables for the external device are firmly connected and that the pins in the cable and connector are not bent.

• Power off the system, reattach the external device, and power on the system.

Newly installed memory is not detected.

• Verify that the memory is properly seated in the DIMM sockets.

• Move the memory to the another DIMM socket to determine whether the socket is defective.

• Verify that you are using 2 GB or 4 GB (667-MHz) fully-buffered DIMM modules with 3.05 cm max. height.

• Verify that the memory modules are installed in pairs.
