There are nine possible subtests to run in intervention and functional modes:
Fcode revision check
Firmware revision check
Board revision check
Checksum Firmware subtest
Selftest
Mailbox Loopback subtest
Internal 10-bit Loopback subtest
Internal 1-bit Loopback subtest
External Loopback subtest
The external loopback test is an intervention test. To test the fibre loop, leave the QLC port attached to the storage. In the Test Parameters Options dialog box, set the "Test if Connected to Storage" option to "Yes". To test the Qlogic 2202 board alone, connect a loopback cable to the QLC port. This cable can be made by taking a regular cable and splitting it apart. Then loop the transmitter side of the port to the receiver side of the port.
For subtest descriptions, see Table 44-1.
