Problems with the Network
The server hangs when the drivers are loaded:
! Change the PCI BIOS interrupt settings. Try the “PCI Installation Tips” below.
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 Link LED doesn’t light:
! Make sure you have loaded the network drivers.
! Check all cable connections.
! Try another port on the hub.
! Make sure you have the correct type of cable between the adapter and the hub.
Some hubs require a crossover cable while others require a straight-through cable
(for more information on crossover cabling, see your hub documentation).
The Activity LED doesn’t light:
! Make sure you’ve loaded the correct network drivers.
! Network may be idle. Try accessing a server.
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 PCI BIOS is current. Try the “PCI Installation Tips” below.
! Make sure the other adapter supports shared interrupts. Also, make sure your
operating system supports shared interrupts; OS/2 does not.
! 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.
