IBM Flex System x440 Compute Node Installation And Service Manual page 503

CAUTION:
Hazardous energy is present when the compute node is connected to the power
source. Always replace the compute node cover before installing the compute
node.
Procedure
To install the compute node in a chassis, complete the following steps.
Handle
1. Select the node bay.
Notes:
a. 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 update options 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.
b. To maintain proper system cooling, do not operate the IBM Flex System
chassis without a compute node or node bay filler in each node bay.
2. Make sure that the front handles on the compute node are in the open position.
3. Slide the compute node into the node bay until it stops.
4. Push the front handles on the front of the compute node to the closed position.
Note: After the compute node is installed, the IMM2 in the compute node
initializes and synchronizes with the Chassis Management Module. This
process takes approximately 90 seconds to complete. The power LED flashes
rapidly, and the power button on the compute node does not respond until this
process is complete.
5. Turn on the compute node (see "Turning on the compute node" on page 13 for
instructions).
6. Make sure that the power LED on the compute node control panel is lit
continuously, indicating that the compute node is receiving power and is
turned on.
7. If you have other compute nodes to install, do so now.
