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 “Server System References” on pagexix for a
link to the 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

•Reseat the adater.
•The network driver files may be corrupt or deleted. Delete and then reinstall the
drivers.
•Run diagnostics.
System Boots when Installing PCI Card
System 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 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.
