v From the CMM web interface, select Compute Nodes from the Chassis
Management menu. For more information, see the "IBM Flex System
Chassis Management Module: User's Guide" at http://

When the compute node is connected to power through the IBM Flex
System chassis, press this button to turn on or turn off the compute node.
Note: The power button works only if local power control is enabled for
the compute node. Local power control is enabled and disabled through
the CMM power command and the CMM web interface.

Flex System Chassis Management Module: Command-Line Interface
Reference Guide" at http://ralfss21.raleigh.ibm.com:8099/help/topic/

After the compute node is removed from the chassis, press and hold this
button to activate the system-board LEDs (light path diagnostics). See
"Compute node controls, connectors, and LEDs" on page 10 for more
information.
This button is also the power LED. This green LED indicates the power
status of the compute node:
v Flashing rapidly: The LED flashes rapidly for one of the following
reasons:
– The compute node has been installed in a chassis. When you install
the compute node, the LED flashes rapidly for up to 90 seconds while
the integrated management module II (IMM2) in the compute node is
initializing and synchronizing with the chassis management module.
– Power permissions have not been assigned to the compute node
through the Chassis Management Module.
– The IBM Flex System chassis does not have enough power to turn on
the compute node.
– The IMM2 in the compute node is not communicating with the
Chassis Management Module.
v Flashing slowly: The compute node is connected to power through the
chassis and is ready to be turned on.
v Lit continuously: The compute node is connected to power through the
chassis and is turned on.
When the compute node is on, pressing this button causes an orderly
shutdown of the compute node so that it can be removed safely from the
