## Install the System Configuration PROM

Note - This is a cold service procedure that must be performed by qualified service personnel. See Cold Service, Replaceable by Authorized Service Personnel for more information about this category of service procedures.

| Caution - The server must be fully shut down and the power cords disconnected.

| Caution - This procedure involves handling circuit boards that are extremely sensitive to static electricity. Ensure that you follow ESD preventative practices to avoid damaging the circuit boards.

| Caution - Components inside the chassis might be hot. Use caution when servicing components inside the chassis.

1. Perform the preliminary steps required for cold service procedures.

   See Cold Service, Replaceable by Customer for instructions.

2. Extend the server out of the rack.

   See Extend the Server.

3. If you can access the rear area of the server without removing the server from the rack, go to Step 5, otherwise remove the server from the rack.

   See Remove the Server From the Rack.

4. Unplug all cables from the server.
5. Remove the top cover.

   See Remove the Top Cover.

6. Align the System Configuration PROM with the socket on the motherboard.

   The notch on the underside of the System Configuration PROM faces the rear of the server.

7. Plug the System Configuration PROM into the socket.

   Gently press down on the center of the System Configuration PROM to ensure that it is fully seated.

8. Install the top cover.

   See Replace the Top Cover.

9. Return the server to its operational position in the rack.

   SeeReturn the Server to the Normal Rack Position.

10. Restore power to the server.

    See Power On the Server (`start` `/SYS` Command) or Power On the Server (Power Button).

    Note - As the system boots up, watch for the banner display in the console output.

11. Verify that the banner display includes an Ethernet address, and Host ID value.

    The Ethernet address and Host ID values are read from the System Configuration PROM. Their presence in the banner verifies that the SP and the host can read the System Configuration PROM.

12. For additional verification, run specific commands to display data stored in the System Configuration PROM.

    - Use the Oracle ILOM `show` command to display the MAC address:

          -> show /HOST macaddress
            /HOST
              Properties:
              macaddress = **:**:**:**:**:**

    - Use Oracle Solaris OS commands to display the `hostid` and Ethernet address:

          # hostid
          8534299c

          # ifconfig -a
          lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232
          index 1
                  inet 127.0.0.1 netmask ff000000
          igb0: flags=201004843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
                  inet 10.6.88.150 netmask fffffe00 broadcast 10.6.89.255
