Turn Off The Server - Lenovo ThinkSystem SR650 V2 Maintenance Manual

Turn off the server

The server remains in a standby state when it is connected to a power source, allowing the Lenovo XClarity
Controller to respond to remote power-on requests. To remove all power from the server (power status LED
off), you must disconnect all power cables.
Note: If there is an OCP 3.0 Ethernet adapter installed, when the system is powered off but still plugged in to
AC power, system fans will continue to spin at a much lower speed. This is the system design to provide
proper cooling for the OCP 3.0 Ethernet adapter.
To place the server in a standby state (power status LED flashes once per second):
Note: The Lenovo XClarity Controller can place the server in a standby state as an automatic response to a
critical system failure.
• Start an orderly shutdown using the operating system (if supported by your operating system).
• Press the power button to start an orderly shutdown (if supported by your operating system).
• Press and hold the power button for more than 4 seconds to force a shutdown.
• Send remote power-off commands to Lenovo XClarity Controller via Lenovo XClarity Essentials OneCLI,
IPMItool, or SSH CLI.
When in a standby state, the server can respond to remote power-on requests sent to the Lenovo XClarity
Controller. For information about powering on the server, see "Turn on the server" on page 14.
