HP NC-Series NetXen 10GbE diagnostics

Please note that network traffic will be interrupted while you are running diagnostic tests. The diagnostic utilities for Windows operating systems perform the following tests:

•Control registers test

•Flash memory test

•Interrupt loop-back test

•Internal loop-back test*

•External full duplex loop-back test*

•Link test

•LED test*

•All tests

* Not supported on NC512m adapters.

To execute the user diagnostic utility in a Windows operating system, complete the following steps:

1.Change to the folder where the softpaq was extracted.

2.Enter the following diagnostic command:

nxudiag.exe -i NX_NIC<Device #>

Where: NX_NIC<Device #> = an interface

Test descriptions

Control registers. Reads the values stored in the control registers. The setting or clearing of specific bits during the initialization process indicates whether the board has been configured correctly. Performs a write/read back/compare operation to selected registers to verify each register's accessibility.

Flash memory. Reads the contents of the flash memory, calculates the checksum, and then compares the calculated checksum to the value stored in memory.

Interrupt loop-back test. Communicates with the driver to force the hardware to generate selected interrupts. Then, the utility reads the interrupt status register to verify that the interrupt was generated and processed.

Internal loopback. Sets the Ethernet core (Media Access Control) to perform a loop-back operation. Sends packets to itself and then compares the contents of the packets to verify that the sent and received values are the same. No external hardware is required for the internal loop-back test.

External loopback. Sends packets to itself through the optical transmit lane, reads the contents on the receive lane, and then compares the contents of the packets to verify that the sent and received values are the same.
