Troubleshooting
Problems with Network
The server hangs when the drivers are loaded.
Certain drivers may require interrupts that are not shared with other PCI drivers. For these
drivers, it may be necessary to alter settings so that interrupts are not shared. See the
documentation that came with your PCI card(s) for information on changing interrupts..
Diagnostics pass but the connection fails.
Make sure the network cable is securely attached.
Make sure you specify the correct frame type in your NET.CFG file.
The controller stopped working when an add-in adapter was installed.
Make sure the cable is connected to the port from the onboard network controller.
Make sure your BIOS is current. See
current version.
Make sure the other adapter supports shared interrupts. Make sure your operating system
supports shared interrupts.
Try reseating the add-in adapter.
The add-in adapter stopped working without apparent cause.
Try reseating the adapter first; then try a different slot if necessary.
The network driver files may be corrupt or deleted. Delete and then reinstall the drivers.
Run the diagnostics.
System Boots when Installing PCI Card
System Server Management features require full-time "standby" power. This means some parts of
the system have power going to them whenever the power cord is plugged in, even if you have
turned the system power off with the power button on the front panel. If you install a PCI card with
the AC power cord plugged in, a signal may be sent to the command the system to boot. Before
installing a PCI card, you should always:
Turn off the server power by using the power button on the front of the system.
Unplug the AC power cord(s) from the server.
