Removing And Replacing Tier 1 Customer Replaceable Units (Crus); Removing The Adapter-Retention Assembly - Lenovo Flex System x440 Compute Node Installation And Service Manual

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.
Step 2. Make sure that the front handles on the compute node are in the open position.
Step 3. Slide the compute node into the node bay until it stops.
Step 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.
Step 5. Turn on the compute node (see
Step 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.
Step 7. If you have other compute nodes to install, do so now.
Step 8. You can place identifying information on the label tabs that are accessible from the front of 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 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

Removing and replacing Tier 1 customer replaceable units (CRUs)

Use this information for removing and replacing Tier 1 CRUs.
Replacement of Tier 1 CRUs is your responsibility. If Lenovo installs a Tier 1 CRU at your request, you will be
charged for the installation.

Removing the adapter-retention assembly

Use this information to remove the adapter-retention assembly.
Before you remove the adapter-retention assembly, complete the following steps:
1. Read "Safety" on page iii
2. If the compute node is installed in a Flex System chassis, remove it (see
from a chassis" on page 880
3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the
bezel pointing toward you.
The adapter-retention assembly consists of five separate parts. You can replace only the parts that you
choose and save the unused parts for future use.
To remove the adapter-retention assembly, complete the following steps.
