Diagnostics for HP NC-Series QLogic nx3/NetXen
nx2 Multifunction adapters
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.
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
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
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.
memory. Reads the contents of the flash memory, calculates
the checksum, and then compares the calculated checksum to the
value stored in memory.
