Closed (on) Power-on password is disabled. 6 Off Configuration validation Invalidates NVRAM configuration information. Open (off) NVRAM is valid. Closed (on) NVRAM is invalid, and configuration is lost.
iLO/Redundant ROM override switch (SW5) The iLO/Redundant ROM override switch (SW5) is a two-position switch that is used for miscellaneous purposes. The iLO security override switch allows you full access to the iLO processor. This access is necessary if you lost your password or if the iLO boot-block must be flashed.
Non-maskable interrupt switch Crash dump analysis is an essential part of eliminating reliability problems such as hangs or crashes in operating systems, device drivers, and applications. Crashes can freeze a system, requiring you to do a hard reset. Resetting the system erases any information that supports root cause analysis. Systems running supported Microsoft operating systems experience a blue screen trap when the operating system crashes.
6 Troubleshooting This chapter provides specific troubleshooting information for the server. Use it to find details about server startup and operation errors. For information on LEDs and switches specific to the server, see Chapter 4, “Server component identification.” For a more detailed discussion of troubleshooting techniques, diagnostic tools, error messages, and preventative maintenance, see the HP Servers Troubleshooting Guide included on the Documentation CD that ships with the server.
If the server does not start This section provides systematic instructions on what to try and where to go for help for the most common problems encountered during initial POST. The server must first complete this test each time you power up, before it can load the operating system and start running software applications. WARNING! A risk of personal injury exists from hazardous energy levels.
Diagnostic steps If the server does not power up or powers up but does not complete POST, answer the questions in Table 27 to determine appropriate actions based on the symptoms observed. The flow of questions reflects the usual flow of events during a power-on sequence. A flow chart following this table illustrates the recommended diagnostic steps and decision options. According to the answers you give, you will be directed to an appropriate secondary table in this section.
Table 29 Is the system power LED green? Answer Possible reasons Possible solutions — A power supply problem exists. The power supply may not be connected or inserted properly, it may have a damaged connector, or it may have failed. Be sure that the power supply is undamaged, the power supply is fully seated, and the power supply LED is green. — The system may have experienced a short. Check for bent connector pins and improperly seated expansion boards. — The front panel LED assembly has failed.
