Troubleshooting Guidelines
10.1
Unable to Boot the Host System with the NIC Card Installed
Remove the NIC and reboot. Does the system boot without the NIC?
If so, power down the system, insert the NIC into a different PCIe slot and boot-up the
system.
Is the recommended minimum memory installed on the host system?
Note any error message during the OS boot sequence.
Check for system error messages:
Dbgview.exe
(Windows event viewer)
dmesg
(Linux)
Use the NetXen diagnostics utility for further testing.
10.2
Unable to ping the NIC Installed on the 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?
Check if the driver is loaded correctly and the card is initialized
- dmesg (display system messages on Linux)
- Windows Event Viewer tool
Run the NetXen user diagnostics
Check the NIC XFP module and optical cables; For CX4, check the IB cable
Check Network Configuration
- Check for valid IP Address and subnet
- Check for duplicate IP address and subnet numbers
- If connected via gateway, check gateway address and network path
- Check the NIC MAC address values
- Network link status as seen by the host OS
- Check for LED activity (using ping)
- Using network monitoring tools, analyze the Tx and Rx packets for the NIC
- Verify the ARP entry and response
