Use the following procedure to replace the CI:
Step 1 Attach an ESD-preventive strap (your own or the one supplied with the FRU) between you and an
unpainted chassis surface.
Step 2 Position the CI in the vertical orientation shown in
CI facing the CI backplane connector. Both CI connectors are keyed so you cannot install the CI
incorrectly; however, to prevent damage to the connector pins, determine the correct connection
orientation before you install the CI.
Step 3 Attach the CI edge connector to the connector on the backplane. Align the CI edge connector keys with
the backplane connector keys; the CI should attach to the backplane connector with a moderate amount
of force. Do not force the CI connector onto the backplane connector. It might be necessary to gently
rock the connectors into place.
