Chapter 3 34 Parts Information
4 Diagnostics Diagnostics Two types of diagnostics support the LH 3000: • Boot Diagnostics These are routines that are executed automatically when the LH 3000 is booted on, and before loading of the Network Operating System (NOS) begins. • DiagTools This is a functional test suite that comes with the LH 3000 and other HP NetServers.
Chapter 4 Diagnostics tests create assurance that hardware is not the source of system problems. This allows the user to eliminate hardware as the cause of the problem and to focus on operating system configuration parameters, network connections, and application software configuration parameters as the source of the problem. If hardware problems are confirmed, the diagnostic software program can sometimes detect and diagnose the subsystem or specific system component that is the cause of the problem.
Chapter 4 Diagnostics Advantages and Limitations of Hardware Diagnostics Off-line diagnostic software is useful in making sure that has been eliminated as the cause for possible system problems. Such diagnostic tools can easily be shipped with a server, and they are relatively easy to use.
Chapter 4 Diagnostics Test Description Interrupt Controller Test Tests the interrupt masks. Test failure at any point causes an error code to be displayed. RAM Address Line Independence Test Verifies the address independence of real-mode RAM (that address lines are not stuck together). Test failure causes an error code to be displayed.

Chapter 5 Troubleshooting 8. If the problem persists, and/or there is an error code, replace the faulty part (the drive, the system board, etc.) 9. If the problem persists, check for environmental problems that can damage disk media and disk drive heads. Environmental problems result from: ◊ Radiated Interference: Sources include communications and radar installations (such as at an airport), radio/TV broadcast transmitters, and hand-held receivers.
Chapter 5 Troubleshooting Network Interface Card Problems See the appropriate Network Interface Card documentation. Symptoms: The adapter can't connect to the network. 1. Make sure the cabling is installed properly. Most hub and switch connections require straight-through cable; consult their documentation. If you're directly connecting two computers (with no hub or other device), use a “crossover” cable. 2.
Chapter 5 Troubleshooting ◊ DC power supply cables to disk drives and/or mass storage cages 4. If the fans aren't audible and the above steps are verified, check that power is getting to all fans. HP NetServers have multiple fans. All fans run when power is turned on; all are off when power is off. With the power supply connected to the system board, check the power supply's voltages. 5. If voltages are not present: a. Turn off AC power. b.
Chapter 5 Troubleshooting BIOS is not current and needs updating (“flashing”). Follow the instructions in the screen to update the BIOS. 8. Check that the external SCSI subsystem BIOS is being executed properly. ◊ When you start the server, the incrementing count of the RAM appears on the screen. Then the external SCSI BIOS displays a banner and a copyright notice. ◊ The BIOS then checks for valid devices on the SCSI bus, and reports which devices are found.
Chapter 5 Troubleshooting 2. If you installed more than one SCSI controller, make sure that the BIOS for all controllers except for the boot controller are disabled. This lets the SCSI BIOS for the boot controller load. 3. Determine what the boot device priority is for the HP NetServer model. Verify that the boot device is set to the correct priority. The SCSI subsystem does not work at installation. Many SCSI problems are caused by an incorrect configuration rather than by faulty hardware.

CAUTION Don't use high voltage differential SCSI devices, they can destroy circuitry on LVD and SE devices. 18. Disconnect all SCSI devices except the SCSI adapter and the drive at SCSI address 0, and try again. If this fails, try substituting a known good SCSI adapter and disk drive. 19.
Chapter 5 Troubleshooting If you have two video monitors connected, test the monitors to make sure they are working (Step 1-4) then go to Step 10. NOTE The system BIOS will beep if no video hardware is detected. This happens when the on-board video is disabled and there is no video adapter board installed. 1. Review the Troubleshooting Checklist before you continue. 2. Check the contrast and brightness controls to make sure they are adjusted. 3.
Chapter 5 Troubleshooting ◊ When some monitors (such as HP high-resolution monitors) are disconnected from the video connector, the monitor may be working, although the screen is black. ◊ If the display is black or white when it should be in color, check the monitor cable to see if a pin is bent. If a pin is bent, slowly but carefully straighten the pin. Replace the cable if the pin cannot be straightened successfully. ◊ If a monitor tester is available, use it to check the display.
Chapter 5 Troubleshooting Installing a PCI board which bridges the two system PCI buses (certain adapter boards provide this feature) can cause previously installed PCI drivers to not recognize their adapter board(s). To resolve the configuration problem, move the PCI board that has bridging capability to a primary PCI slot. The configuration cannot be saved and the battery loses power. Refer to this section if the server frequently loses date and time that may be caused by the battery losing power. 1.
Chapter 5 Troubleshooting 2. During the Power on Self-Test (POST) early in the boot sequence, watch the two LEDs on each hard disk drive module. ◊ Status LEDs: All LEDs quickly cycle from amber to steady green. ◊ Activity LEDs: All LEDs quickly cycle from amber to green.
