b. Close the server fan door.

See “Return the Server to the Normal Rack Position” on page 148.
d. Reconnect the data cables to the server and reconnect the power cords to the
server power supplies.
See “Reconnect Data Cables and Power Cords” on page 149.
e. Power on the server.
See “Power On the Server” on page 150.
Verify that the Power/OK status indicator is steady on.
Note – IMPORTANT: After replacing the motherboard, you might need to manually
program the product serial number (PSN) into the new motherboard. This is
necessary because the motherboard is a secondary member of a select group of
components that maintain the PSN for service entitlement. If you have replaced more
than one of the members of this select group during any given service procedure, a
secondary group member might need to be programmed with the PSN. To propagate
the FRU top-level indicator (TLI) data to the new motherboard, you must reset the
Oracle ILOM service processor (SP). For instructions on resetting the SP, see the
Oracle Integrated Lights Out Manager (ILOM) 3.1 Configuration and Maintenance
Guide at http://www.oracle.com/goto/ILOM/docs
