Powering On and Off the Server

Use the following procedures to power on and power off the Sun Netra X4450.

Apply Main Power for All Server Components

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

In standby power mode, the Power OK Indicator on the front panel flashes.

Use a pen, or other pointed object, to press and release the recessed Power button on the server front panel.

When the main power is applied to the server, the Power OK Indicator 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.

Power Off From Main Power Mode

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

**TABLE 7-1 Shutdown Methods**
Shutdown	Method
Graceful shutdown	Use a pen, or other pointed object, to press and release the Power button on the front panel. This action 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 shut down to Standby power mode immediately.
Emergency shutdown	Press and hold the Power button for at least four seconds to force the main power off and cause the server to enter standby power mode. When the main power is off, the Power/OK Indicator on the front panel begins flashing, indicating that the server is in standby power mode.

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

Setup Troubleshooting

This section contains information to help you troubleshoot minor server problems. If you experience problems while setting up your server, refer to the troubleshooting information in TABLE 7-2.

**TABLE 7-2 Troubleshooting Procedures**
Problem	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? Is the monitor power cord connected to the monitor? 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 are complete, you no longer see video output on your monitor and see only 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.
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 service: Is the Power Indicator 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 indicator 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 Indicator is illuminated.
Server appears to be in low power mode, but the Power Indicator does not blink.	The Power Indicator 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 Indicator does not blink.
Hung or frozen server: No response from mouse or keyboard or any application.	Try to access your system from a different server on the network: On another system, type `ping` `IP_address_of_server`. If a response is returned, then try logging in to the Sun Netra X4450 using either `telnet`, `ssh`, or `rlogin`. If you successfully log in, list the running processes using the `ps` command. Kill any processes that appear unresponsive or should not be running, by using the `kill` `process_ID` command. Check the responsiveness of the Sun Netra X4450 after each process is killed. If this procedure does not work, power cycle the server: Press the Power button to power off the server and wait 20 to 30 seconds. Press the Power button again to power system back on.

Note - For additional troubleshooting information, see the Sun Netra X4450 Server Service Manual.
