Power Down Server Gracefully Using the Power Button
Note – You can use the Power button on the front of the server to power down the
server gracefully.
1. Press and quickly release the Power button on the front panel.
This action causes 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.
When main power is off, the Power/OK LED on the front panel will begin
flashing, indicating that the server is in standby power mode. See
“Server General
Status Indicators” on page 7 .
2. Disconnect the power cords and data cables from the server.
See “Disconnect Cables From the Server” on page 39 .
Caution – When you press the Power button to enter standby power mode, power
is still directed to the service processor remote management subsystem and power
supply fans. To completely power off the server, you must disconnect the power
cords from the power supplies.
