Step 1. Locate the TCM connector on the system board (see “System-board connectors” on page 13).
Step 2. If an I/O expansion adapter is installed in the I/O expansion 1 connector (see “System-board
connectors” on page 13 for the location of the connector), you will need to remove it first (see
“Remove an I/O expansion adapter” on page 57 ), as it will block your access to the TCM
connector.
Step 3. Touch the static-protective package that contains the TCM 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 TCM from the package.
Step 4. Carefully hold the TCM by its edges and insert it into the TCM connector on the system board.
After you install the TCM, 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.
