By upgrading the system firmware,system can support new devices,better performance,better availability and add more security  to the system. In a order to upgrade the system firmware,y ou need to halt the server before upgrading the system firmware.Here we will see how to upgrade the system firmware on SUN T5220 server.



1. Login to the lom using admin account .

NOTE: A firmware upgrade will cause the server and ILOM to
      be reset. It is recommended that a clean shutdown of
      the server be done prior to the upgrade procedure.
      An upgrade takes about 6 minutes to complete. ILOM
