Remove the compute node from the chassis
Use this information to remove the compute node from the Lenovo Flex System chassis.
Before you remove the compute node:
1. Read “Safety” on page iii and “Installation Guidelines” on page 21 to ensure that you work safely.
2. Power off the corresponding compute node that you are going to perform the task on.
3. Record the serial number for each node bay.
To remove the compute node from the chassis, complete the following steps:
Watch the procedure. A video of the installation process is available:

Figure 8. Compute node removal from chassis
Step 1. Pull 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 Lenovo 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 the node bay
