Installing a compute node in a chassis

Use this information to install a compute node in a Lenovo ThinkServer n400 Enclosure Type 5495 chassis.

Before you install the compute node in a chassis, read Safety and Installation guidelines.
Statement 21
Graphic illustrating the Safety statement 1 symbol
CAUTION
Hazardous energy is present when the compute node is connected to the power source. Always replace the compute node cover before installing the compute node.

To install the compute node in a chassis, complete the following steps.

  1. Select the node bay.
    Note
    1. 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.
    2. To maintain proper system cooling, do not operate the Lenovo ThinkServer n400 Enclosure Type 5495 chassis without a compute node, or node bay filler in each node bay.
  2. Install the air baffle properly in the position before sliding the compute node.
  3. Slide the compute node into the node bay until it stops.
    Note
    The time required for a compute node to initialize varies by system configuration. The power LED flashes rapidly; the power button on the compute node does not respond until the power LED flashes slowly, indicating that the initialization process is complete.
  4. Turn on the compute node (see Turning on the server for instructions).
  5. Make sure that the power LED on the compute node control panel is lit continuously, indicating that the compute node is receiving power and is turned on.
  6. If you have other compute nodes to install, do so now.
Important
If an Attention label is on the front panel of the compute node above the power button, read it; then, remove the label and discard it before turning on the compute node.

If this is the initial installation of the compute node in the chassis, you must configure the compute node through the Setup utility and install the compute node operating system. See Updating the compute node configuration and operating-system documentation for details.

If you have changed the configuration of the compute node or if you are installing a different compute node from the one that you removed, you must configure the compute node through the Setup utility, and you might have to install the compute node operating system (see Using the Setup utility).
