WARNING: Only authorized technicians trained by HP should attempt to repair this equipment. All troubleshooting and repair procedures are detailed to allow only subassembly/module-level repair. Because of the complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard. WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that: • The leveling feet are extended to the floor. • The full weight of the rack rests on the leveling feet. • The stabilizing feet are attached to the rack if it is a single-rack installation. • The racks are coupled together in multiple-rack installations. • Only one component is extended at a time. A rack may become unstable if more than one component is extended for any reason. Symptom information Before troubleshooting a server problem, collect the following information: • What events preceded the failure? After which steps does the problem occur? • What has been changed since the time the server was working? • Did you recently add or remove hardware or software? If so, did you remember to change the appropriate settings in the server setup utility, if necessary? • How long has the server exhibited problem symptoms? • If the problem occurs randomly, what is the duration or frequency? To answer these questions, the following information may be useful: • Run HP Insight Diagnostics (on page 49) and use the survey page to view the current configuration or to compare it to previous configurations. • Refer to your hardware and software records for information. • Refer to server LEDs and their statuses. Prepare the server for diagnosis 1. Be sure the server is in the proper operating environment with adequate power, air conditioning, and humidity control. For required environmental conditions, see the server documentation. 2. Record any error messages displayed by the system. 3. Remove all diskettes, CD-ROMs, DVD-ROMs, and USB drive keys. 4. Power down the server and peripheral devices if you will be diagnosing the server offline. If possible, always perform an orderly shutdown: a. Exit any applications. b. Exit the operating system. c. Power down the server ("Power down the server blade" on page 11). 5. Disconnect any peripheral devices not required for testing (any devices not necessary to power up the server). Do not disconnect the printer if you want to use it to print error messages. Troubleshooting 55
