v From the CMM web interface, select Compute Nodes from the Chassis
Management menu. For more information, see the "Flex System Chassis
Management Module: User's Guide" at http://pic.dhe.ibm.com/
infocenter/flexsys/information/topic/com.ibm.acc.cmm.doc/
cmm_user_guide.html. All fields and options are described in the CMM
web interface online help.
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 11 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 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
Flex System chassis and is ready to be turned on.
v Lit continuously: The compute node is connected to power through the
Flex System 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
chassis. This includes shutting down the operating system (if possible) and
removing power from the compute node.
If an operating system is running, you might have to press the button for
approximately 4 seconds to initiate the shutdown.
Attention: Pressing the button for 4 seconds forces the operating system to
shut down immediately. Data loss is possible.
Connect the console breakout cable to this connector (see "Console
breakout cable" on page 15 for more information).
Note: It is best practice to connect the console breakout cable to only one
compute node at a time in each Flex System chassis.
Connect a USB device to this connector.
Note: It is best practice to connect a USB device to the front of only one
compute node at a time in each Flex System chassis.
