Installing a compute node in a chassis

Use this information to install a compute node in a Flex System chassis.

• Before you install a x440 Compute Node Types 7167 and 2590 in a chassis that is managed by Flex System Manager management software, make sure that the management software is version 1.1.1.0 or later. To determine whether your management software must be updated, and for more information about downloading and installing an update, see the "Updating systems" section of the "Flex System Manager Software: Installation and Service Guide".
• Before you install a x440 Compute Node Types 7167 and 2590 in a chassis, make sure the Chassis Management Module firmware release date is 08/20/2012 or later. To determine whether your CMM firmware must be updated, log on to the Chassis Management Module web interface. Click on the Chassis Management Module in the graphical user interface; then, select Firmware . To update the CMM firmware to the latest release, see the Fix Central website. Select PureSystems, PureFlex System, Chassis, Enterprise Chassis, Your operating system and Continue.
• If you are installing a compute node model that does not have an integrated Ethernet controller, you must install a network interface adapter before you install the compute node in the chassis for management network communication. For a list of supported optional devices for the compute node, see the Lenovo ServerProven website.

Before you install the compute node in a chassis, read Safety and Installation guidelines.

Statement 21

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 Flex System chassis without a compute node or node bay filler in each node bay.
2. Make sure that the front handles on the compute node are in the open position.
3. Slide the compute node into the node bay until it stops.
4. Push the front handles on the front of the compute node to the closed position.
   Note

   After the compute node is installed, the IMM2 in the compute node initializes and synchronizes with the Chassis Management Module. This process takes approximately 90 seconds to complete. The power LED flashes rapidly, and the power button on the compute node does not respond until this process is complete.
5. Turn on the compute node (see Turning on the compute node for instructions).
6. 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.
7. If you have other compute nodes to install, do so now.
8. You can place identifying information on the label tabs that are accessible from the front of the compute node.
