Problem Cause Solution
Diagnostics passes, but the
workstation does not
communicate with the network.
Network drivers are not loaded, or
driver parameters do not match
current configuration.
1. Verify that the network drivers are loaded and that
the driver parameters match the configuration of the
network controller.
2. Verify that the correct network client and protocol is
installed.
The network controller is not
configured for this workstation.
Double-click the Network icon in the Control Panel and
configure the network controller.
Network controller stopped
working when an expansion
board was added to the
workstation.
Network controller interrupt is
shared with an expansion board.
In the Computer Setup (F10) Utility Advanced menu,
change the resource settings for the board.
The network controller requires
drivers.
Verify that the drivers were not accidentally deleted when
the drivers for the expansion board were installed.
The expansion board installed is a
network card and conflicts with the
embedded network card.
Under the Computer Setup (F10) Advanced menu,
change the resource settings for the board.
Network controller stops working
without apparent cause.
The files containing the network
drivers are corrupted.
Reinstall the network drivers using the Restore Plus! CD,
or download and install the latest drivers from
http://welcome.hp.com/country/us/en/support.html.
The cable is not securely
connected.
Be sure that both ends of the cable are securely attached
to the correct devices.
The network controller is
defective.
Replace the Network Interface Controller, or replace the
system board when using an onboard NIC.
New network card does not boot. New network card might be
defective or might not meet
industry-standard specifications.
Install a working, industry-standard Network Interface
Controller, or change the boot sequence to boot from
another source.
Cannot connect to network
server when attempting remote
system installation.
The network controller is not
configured properly.
Verify that:
●
Network connectivity is functioning
●
A DHCP server is present
●
Remote System Installation Server contains the
Network Interface Controller drivers for your NIC
Computer Setup (F10) Utility
reports unprogrammed
EEPROM.
Unprogrammed EEPROM. Flash the ROM.
Solving memory problems
CAUTION: For systems that support ECC memory, HP does not support mixing ECC and nonECC
memory. The operating system does not boot with mixed-ECC memory.
Table 5-13 Memory problems
Problem Cause Solution
System does not boot (or does not
function) after installing additional
memory modules.
A memory module is not the
correct type or speed, or the
new memory module is not
seated properly.
Replace the module with the correct, industry-standard
device for the workstation.
On some models, ECC and nonECC memory modules
cannot be mixed.
