F. Press ENTER to Continue with programming. 4. Remove the diskette and press ENTER to reboot the system. CAUTION Although the Flash Memory Utility includes safeguards to protect the NVRAM from damage, it is still possible to damage the server's NVRAM if there is a loss of power while the update is in progress. You will see a warning about this before the update process begins. If the update is in progress and there is a loss of power to the server, you must replace the system board. You will not be able to use the server until the new system board is installed. If the Flash Update Utility indicates that it has encountered errors during the update process, you will be requested to either retry or abort the operation. PLEASE RETRY the update at least once before aborting the operation. Aborting the operation damages the EPROM, and you will have to replace the system board. However, as long as you do not remove power from the server, you may still be able to use the server until you receive the replacement system board. Using the Configuration Utility with the HPUpdate Utility If configuration utility requests that you insert the Flash Memory Utility diskette into drive A, you do not have to restart (reboot) the system to use the Flash Memory Utility. The configuration utility will ensure a SAFE environment before asking you to put the Flash Memory Utility diskette into drive A. HP NetServer DiagTools DiagTools for HP NetServers is a set of off-line diagnostic tests, including tests for system and processor components, memory and storage elements, ports, and input/output devices. DiagTools is supplied on the HP NetServer Navigator with HP NetServer series LC, LH, LP and LX and later systems. The user prepares DiagTools software for use by transferring it to diskette. Then the DiagTools diskette is used to boot the server. A basic suite of tools checks key NetServer components, and a menu of advanced tests is available for in-depth testing. DiagTools has the capability to test the following components: l system board l processors l memory modules l hard disk drives l flexible disk drives l keyboards l serial ports l parallel ports l video monitor l CD-ROM drives DiagTools is an off-line diagnostic test series. Off-line diagnostics do not use the main operating system (OS) of the HP NetServer. The alternate DiagTools OS has far fewer features than the full-fledged OS. Thus, its capabilities are limited to a set of basic tests and a series of advanced tests. In addition, DiagTools does not use any tests which might write over and thus destroy user data. Tests which require user inputs or decisions are left to the advanced series of tests. Advantages and Limitations of Hardware Diagnostics Off-line diagnostic software should be used only by experienced personnel who can take a wider view of its limitations, which include: • booting the server from the diagnostics diskette 24

Although the Flash Memory Utility includes safeguards to protect the NVRAM from
damage, it is still possible to damage the server's NVRAM if there is a loss of power
while the update is in progress. You will see a warning about this before the update

If the update is in progress and there is a loss of power to the server, you must replace the system board.
You will not be able to use the server until the new system board is installed.

limitations, which include:
