Removing a compute node from a chassis

Use this information to remove a compute node from a Lenovo ThinkServer n400 Enclosure Type 5495 chassis.

Before you remove a compute node, complete the following steps:
  1. Read Safety and Installation guidelines.
  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 server for more information).
  4. Record the serial number for each node bay.

To remove the compute node from a chassis, complete the following steps:

  1. Unhook the latch by pushing the side way.

    Attention
    • To maintain proper system cooling, do not operate the Lenovo ThinkServer n400 Enclosure Type 5495 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.
  2. Pull the compute node out of the node bay.
  3. Install either a node bay filler or another compute node in the node bay.

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.
