Loopback Test
The loopback test is a diagnostic tool that routes transmit data through a loopback
connector back to the same adapter.
Link Test
The link test inspects the link status (up or down) by checking the physical
communication channel between the host and the firmware.
Windows Diagnostic Test Messages
If a test fails, an appropriate error code is generated and displayed, as shown in
Table 3-9
