Shutting Down and Removing Power From the Server

The server can run in either of two power modes:
• Main power mode—Power is supplied to all server components and any operating system on your drives
• Standby power mode—Power is supplied only to the service processor and certain components. It is safe
Caution After a server is shut down to standby power, electric current is still present in the server. To completely
remove power as directed in some service procedures, you must disconnect all power cords from all power
supplies in the server.
You can shut down the server by using the front-panel power button or the software management interfaces.

Shutting Down Using the Power Button

Step 1 Check the color of the Power button/LED:
• Amber—The server is already in standby mode and you can safely remove power.
• Green—The server is in main power mode and must be shut down before you can safely remove power.
Step 2
Invoke either a graceful shutdown or a hard shutdown:
Caution To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown of the
operating system.
• Graceful shutdown—Press and release the Power button. The operating system performs a graceful shutdown and
the server goes to standby mode, which is indicated by an amber Power button/LED.
• Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off and immediately
enter standby mode.
Step 3 If a service procedure instructs you to completely remove power from the server, disconnect all power cords from the
power supplies in the server.
