Powering Off the Server

There are two methods for shutting down the server from main power mode to standby power mode.

• Graceful shutdown – Use a pencil or other pointed object 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 main power off and enter standby power mode.

When main power is off, the Power/OK LED on the front panel begins flashing, indicating that standby power is still available.

Once the server is powered down, complete the following steps before removing the main cover:

1. Unplug all AC power cords from the server’s power supplies.
2. Turn off all peripheral devices connected to the system.
3. Label any peripheral cables and/or telecommunication lines that must be disconnected in order to remove and replace a specific component.
