Chapter 6 Troubleshooting If the System Powers On but the System Fails the POST (Power-On Self Test) Do one of the following: • If the system gives a series of beeps, this indicates a system error. Contact HP or your reseller. • If the system fails POST and an error message displays on the screen, see the section "Error Messages." If the suggested solutions do not solve your problem, contact HP or your reseller. If the System Passes the POST (Power-On Self Test) but Will Not Function If an error message displays on the screen, read the error message text for actions to take. If the actions do not solve your problem, contact your reseller. If there is no error message, follow these steps: 1. Check to ensure that the HP NetServer is configured correctly in the EISA Configuration Utility. 2. If the server still does not work, turn it off and remove all external peripherals, except the monitor and keyboard. Test to see if the server now works. 3. If the server still doesn't work, turn off the monitor, the server, and all external devices, and check the internal hardware, as follows: a. Unplug the power cord and all telephone cables. Remove the HP NetServer cover. b. Check that all accessory boards are firmly seated in their slots. c. Ensure that all disk drive power and data cables are securely and properly connected. Verify the mass storage configuration with the cabling and switch diagrams in Chapter 3. d. Verify that switches and jumpers on the upper-shelf mass storage devices and boards are properly set. Check the manuals that came with the devices. e. Verify that the DIMMs are firmly seated on the Processor Board. Verify that added DIMMs are HP DIMMs (see the Technical Information Label on top of the chassis for order numbers). 30
