Note: When setting power redundancy through FPC after nodes are powered on,
it is possible that the current power bank is not sufficient to allow N+1 or N+N
configuration. Remove some or all of the nodes or lighten nodes configuration
before the redundancy policy can be applied.
To install the compute node in a chassis, complete the following steps.

Figure 18. Installing the compute node in a IBM NeXtScale n1200 Enclosure
1. Select the node bay.
2. Make sure that the front handle on the compute node is in the open position.
3. Slide the compute node into the node bay until it stops.
4. Push the front handle on the front of the compute node to the closed position.

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 NeXtScale n1200
Enclosure without a compute node or node bay filler in each node bay.
Note: After the compute node is installed, the IMM2 in the compute node
initializes and synchronizes with the Chassis Management Module. This
