AlterPath BladeManager Manual 2-27
• If your operating system supports the Wake on LAN feature, the Wake on
LAN feature can switch on the BladeManager.
Note: When 4 GB or more memory (physical or logical) is installed, some
memory is reserved for various system resources and is unavailable to
the operating system. The amount of memory that is reserved for
system resources depends on the operating system, the BladeManager
configuration, and the configured PCI options.
Switching Off the BladeManager
When you switch off the BladeManager and leave it connected to AC power,
the BladeManager can respond to requests from the Service processor, such
as a remote request to turn on the server. To remove all power from the server,
you must disconnect it form the power source.
Caution: The power control button on the device and the power switch on
the power supply do not turn off the electrical current supplied to
the device. The device also might have more than one power cord.
To remove all electrical current from the device, ensure that all
power cords are disconnected from the power source.
You can switch off the BladeManager in any of the following ways:
• You can switch off the BladeManager from the operating system if your
operating system supports this feature. After an orderly shutdown of the
operating system, BladeManager will switch off automatically.
• You can press the power-control button to start an orderly shutdown of
the operating system and switch off the BladeManager if your operating
system supports this feature.
• If the operating system stops functioning, you can press and hold the
power-control button for more than 4 seconds to switch off the
BladeManager.
• If the BladeManager is connected to an Advanced System Management
interconnect network that contains at least one server with an optional
Remote Supervisor Adapter II installed, the BladeManager can be
switched off from the Remote Supervisor Adapter II user interface.
• If an optional Remote Supervisor Adapter II is installed in the server, the
server can be switched off from the Remote Supervisor Adapter II user
interface.
