The servers provide many ways to monitor system activity and faulty behavior, including LEDs, Oracle ILOM, and POST. Log files, including system console activity, are maintained by Oracle Solaris and Oracle ILOM. For specific information about LEDs, fault reports, and log files, refer to the topics on detecting and managing faults in the service manual for the server.
