Step 1. Select the node bay.
Notes:
• If you are reinstalling a compute node that you removed, you must install it in the same node bay
from which you removed it. Some compute node configuration information and updates are
established according to node bay number. Reinstalling a compute node into a different node
bay can have unintended consequences. If you reinstall the compute node into a different node
bay, you might have to reconfigure the compute node.
• To maintain proper system cooling, do not operate the Flex System chassis without a compute
node, or node bay filler in each node bay.
Step 2. Make sure that:
• Air baffle is installed in the compute node
• Compute node cover is in place and secure
• Both front handles are in the fully open position
Step 3. Slide the compute node into the node bay until it stops.
Step 4. Rotate both handles inward to push the compute node until the spring loaded releases snaps into
place.
Note: After the compute node is installed, the Lenovo XClarity Controller in the compute node
initializes and synchronizes with the CMM. The time required for a compute node to initialize varies
by system configuration. The power LED flashes rapidly when processing; the power button on the
compute node does not respond until the power LED flashes slowly, indicating that the initialization
process is complete.
Step 5. If you have other compute nodes to install, do so now.
If this is the initial installation of the compute node, you must configure the compute node through the Setup
utility and install the compute node operating system. See Chapter 4 “System configuration” on page 61 for
details.
If you have changed the configuration of the compute node or if you are installing a different compute node
from the one that you removed, you must configure the compute node through the Setup utility, and you
might have to install the compute node operating system. See “Install the operating system” on page 66 for
details.
Power on the compute node
Use this information for details about power on the compute node.
The compute node can be turned on (power-on LED on) in any of the following ways:
• You can press the power button.
• The compute node can restart automatically after a power interruption.
• The compute node can respond to remote power-on requests sent to the Lenovo XClarity Controller.
For information about powering off the compute node, see “Power off the compute node” on page 60.
Validate compute node setup
After powering up the compute node, make sure that the LEDs are lit and that they are green.
