Removing a compute node from a chassis
Use this information to remove a compute node from a Flex System chassis.
Before you remove a compute node, complete the following steps:
1. Read “Safety” on page iii and “Installation guidelines” on page 637.
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 16
for more information).
To remove the compute node from a chassis, complete the following steps:
Step 1. Open the front handle as shown in the illustration. The compute node moves out of the node
bay approximately 0.6 cm (0.25 inch).

Attention:
• To maintain proper system cooling, do not operate the Flex System chassis without a compute
node or node bay filler installed in each node bay.
• When you remove the compute node, note the node bay number. Reinstalling a compute
node into a different node bay from the one it was removed from can have unintended
consequences. Some configuration information and update options are established according
to node bay number. If you reinstall the compute node into a different node bay, you might have
to reconfigure the compute node.
Step 2. Pull the compute node out of the node bay.
Step 3. Install either a node bay filler or another compute node in the node bay within 1 minute.
If you are instructed to return the compute node, follow all packaging instructions, and use any packaging
materials for shipping that are supplied to you.
