Diagnostics for HP NC-Series QLogic nx3/NetXen nx2 Multifunction adapters

• Control Registers. Reads the values stored in the control registers. The setting that clears 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.
• 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. Not supported on HP NC512x adapters.
• External Loopback. This test contains all of the associated handshake signals required to redirect the four transmit lanes to the four receive lanes. In this test the utility sends packets to itself through the transmit lane, reads the contents on the receive lane, then compares the contents of the packets to verify that the sent and received values are the same. External hardware is required to test the full duplex loopback test. For NC510C adapters, the external module connects the transmit lanes to the corresponding receive lanes and for the NC510F adapters, an 850 nm multimode cable with LC connections is required to externally connect the transmit lane to the receive lane. Not supported on HP NC512x adapters.
• Link. Reports the status of the link as up or down.
• Interrupt. 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.
• Flash memory. Reads the contents of the flash memory, calculates the checksum, and then compares the calculated checksum to the value stored in memory.
