When the compute node starts for the first time after you add or remove an
internal device, you might receive a message that the configuration has changed.
The Setup utility automatically starts so that you can save the new configuration
settings. See “Using the Setup utility” on page 26 for more information about the
Setup utility.
Some devices have device drivers that you must install. See the documentation
that comes with each device for information about installing device drivers.
The compute node operates as a symmetric multiprocessing (SMP) compute node,
regardless of how many microprocessors are installed. For optimum performance,
you must upgrade the operating system to support SMP. See Chapter 3, “Installing
the operating system,” on page 39 and your operating-system documentation for
additional information.
Removing a compute node from a chassis
Use this information to remove a compute node from a IBM Flex System chassis.
Before you begin
Before you remove a compute node, complete the following steps:
1. Read “Safety” on page v and “Installation guidelines” on page 487.
2. If the compute node is operating, shut down the operating system.
3. Press the power button to turn off the compute node (see “Turning off the
compute node” on page 15 for more information).
Procedure
To remove the compute node from a chassis, complete the following steps:
1. Open the front handles as shown in the illustration. The compute node moves
out of the node bay approximately 0.6 cm (0.25 inch).
