Chapter 6 Memory Problems The memory modules used for this server are PC2100 DDR 266 MHz ECC DIMMs. Troubleshooting NOTE If the POST (displayed at power-on time) indicates a defective memory module, replace it. Action: 1. Review the Troubleshooting Checklist before you continue. 2. If memory problems are being experienced, power the server off and on. This performs a "cold" restart, rather than a "warm" restart (as it does when you press Ctrl+Alt+Del). 3. Reseat the memory modules. 4. Run the Diagnostics for Windows utility memory test. 5. To check that the modules are installed and configured correctly: a. Run the (BIOS) Setup Utility (press F10 during the boot process) and check the configuration. b. Install one known good DIMM. If you still receive an error, replace the system board. c. If the error goes away, add another DIMM and reboot again. d. Continue this process until you have installed all DIMMs or you experience a failure. e. Replace the defective DIMM. 6. Once a suspect part has been found, verify the cause of the problem by reinstalling the part and attempting to duplicate the error. Also install it in another memory socket to confirm whether or not the socket is defective. Embedded Network Interface Card Problems See the appropriate Network Interface Card documentation. Symptom: • The NIC adapter cannot connect to the network. Action: 1. Check power to the server. 2. Ensure the proper drivers are installed. 3. Check the LAN cable connection on the device and the server. 4. Check the LAN status and activity LEDS are on. See "Standard LAN Connector" in Chapter 2, External Connectors. 5. If the LAN status light is off, replace the system board. 6. If the problem persists, contact your system administrator or HP Customer Support provider. 77

Troubleshooting
Memory Problems
The memory modules used for this server are PC2100 DDR 266 MHz ECC DIMMs.
Action:
1.
Review the Troubleshooting Checklist before you continue.
2.
If memory problems are being experienced, power the server off and on. This performs a “cold” restart,
rather than a “warm” restart (as it does when you press Ctrl+Alt+Del).
3.
Reseat the memory modules.
4.
Run the Diagnostics for Windows utility memory test.
5.
To check that the modules are installed and configured correctly:
a.
Run the (BIOS) Setup Utility (press F10 during the boot process) and check the configuration.
b.
Install one known good DIMM. If you still receive an error, replace the system board.
c.
If the error goes away, add another DIMM and reboot again.
d.
Continue this process until you have installed all DIMMs or you experience a failure.
e.
Replace the defective DIMM.
6.
Once a suspect part has been found, verify the cause of the problem by reinstalling the part and attempting
to duplicate the error. Also install it in another memory socket to confirm whether or not the socket is
