1. J Test DMA The Test DMA option performs a test to ensure the ability of the microprocessor to perform a DMA transfer properly Values are put into a buffer which is then trans ferred using a DMA write to the SNIC s ring buffer The values are then read back into a separate buffer using a DMA read operation then the two buffers are compared to ensure that the values read back are the same as those written to the ring buffer The test is passed if the values read back are identical to those written K Ethernet Mirror Test The Ethernet mirror test requires another module or node that understands 802 2 mes sages of type TEST The mirror test composes and transmits a TEST type message over the Ethernet and waits for a response The responses to 802 2 TEST messages are just a reply to the message with the same data and the reversal of the destination and source addresses by the receiver This test requires a test for timeout in the event that no response is received If no response is received or the response received is not what is expected the appropriate error message will be displayed otherwise the pass condi tion message will be displayed L Ethernet TDR Test This option performs the 3 loopback test on the SNIC The first two are internal tests of the SNIC This test requires one of the Ethernet ports to be connected to a valid net work The SNIC transmits data out onto the Ethernet network and receives it at the same time Th
