Troubleshooting Guidelines

6.1

Unable to Boot the Host System with the NIC Card Installed

„

Remove the NIC and reboot. Does the system boot without the NIC?

„

Is the recommended minimum memory installed on the host system?

„

Refer to Section 6.4, "Caveats" for the 2-Gbyte Windows or 1-GByte Linux 
configuration entries.

„

Note any error message during the OS boot sequence.

„

Is the ROM scan enabled in the BIOS? If so, disable it.

„

Check for system error messages:

Dbgview.exe

 (Windows event viewer)

dmesg

 (Linux)

Use the NetXen diagnostics utility for further testing.

6.2

Unable to ping the NIC Installed on Linux Host

„

Type 

lspci -v

 and look for vendor ID ‘4040’. Is the NIC visible on the PCI bus?

„

Is the NIC is placed in the PCIe x8 slot?

6.3

Gather System Information and Check for Errors on Linux Host

cat /proc/modules | grep -i nx

cat /proc/pci

cat /proc/interrupts

ethtool -i <network interface>

lspci -v

lspci -vt

„

Check for error messages from the kernel:

„

Type 

dmesg

„

Type 

cat /var/log/messages

„

Check routing table, gateway, and IP Address conflicts for all interfaces:

„

Type 

route

„

Check network interface TX and RX counts during pings:

„

Type 

ifconfig <network interface>

„

Use 

ethereal

tethereal

nospace

, or 

tcpdump

 utilities to capture packets:
