Shutting Down and Powering Off the Server

The server can run in two power modes:

•Main power mode—Power is supplied to all server components and any operating system on your drives can run.

•Standby power mode—Power is supplied only to the service processor and the cooling fans and it is safe to power off the server from this mode.

You can invoke a graceful shutdown or an hard shutdown by using either of the following methods:

•Use the CIMC management interface.

•Use the Power button on the server front panel. To use the Power button, follow these steps:

Step 1 Check the color of the Power Status LED (see the “Front Panel LEDs” section on page 3-2).

•Green—the server is in main power mode and must be shut down before it can be safely powered off. Go to Step 2.

•Amber—the server is already in standby mode and can be safely powered off. Go to Step 3.

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 Status 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 Disconnect the power cords from the power supplies in your server to completely power off the server.
