Power States
The HP Integrity BL60p server blade has three power states: standby power, full power, and off. You must
install the server blade into the enclosure to achieve the standby and full power states. Depending on your
server blade settings, the server blade may go straight to full power when it is installed into the enclosure.
The enclosure should always have power applied to it, so the only way to remove all power from the server
blade is to remove it from the enclosure. Table 3-1 describes the server power states:
Power Off the Server
The following procedure describes how to power off your HP Integrity entry-class server.
Step 1. Gracefully shut down your OS by pressing the power button (for less than five seconds).
IMPORTANT Momentarily pressing the power button initiates an ACPI graceful shutdown of the
server blade. This process can take as long as 30 seconds, during which time the only
observable feedback is the blinking disk activity light. The system power goes to
standby mode. When the system goes into standby mode, the power LED turns from
green to amber.
Holding the power button for five seconds forces a sudden power-off. This should only
be used if the system has hung, and does not respond to a graceful power-off. Data
loss may occur depending on the current state and activity of the system.
Step 2. The server blade is now in standby power mode. To remove all power to the server blade, remove
the server blade from the enclosure. Refer to “Removing and Replacing the Server Blade from the
Enclosure” on page 45.
