Figure 42. I/O expansion adapter installation
Step 1.
Locate the I/O expansion connectors.
Step 2.
Remove the expansion cover from the connector, if one is present.
Step 3.
Touch the static-protective package that contains the expansion adapter to any unpainted metal
surface on the Lenovo Flex System chassis or any unpainted metal surface on any other grounded
rack component; then, remove the expansion adapter from the package.
Step 4.
Rotate the retention clips outward.
Step 5.
Orient the connector on the expansion adapter with the I/O expansion connector and alignment
pins on the system board; then, press the adapter into the I/O expansion connector.
Step 6.
Firmly press on the indicated locations to seat the expansion adapter in the connector and over the
alignment pins.
Step 7.
Close the retention clips to secure the adapter.
After you install the I/O expansion adapter, complete the following steps:
1. Install the compute node cover (see "Install the compute node cover" on page 43 ).
2. Install the compute node into the chassis (see "Install the compute node in the chassis" on page 25 ).
3. Power on the compute node.
4. See the documentation that comes with the expansion adapter for device-driver and configuration
information to complete the installation.

2. Power off the corresponding compute node that you are going to perform the task on.
3. Remove the compute node from the chassis (see "Remove the compute node from the chassis" on page
24).
4. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the
bezel pointing toward you.
