Loopback Test Combinations
Run the following loopback test combinations using the appropriate checkboxes:
PCI Loopback Test – A firmware controlled diagnostic test in which a random
data pattern is routed through the PCI Bus without being sent to an adapter link
port. The returned data is subsequently validated for integrity.
Internal Loopback Test – A diagnostic test in which a random data pattern is
sent down to an adapter link port, then is immediately returned without
actually going out on the port. The returned data is subsequently validated for
integrity.
External Loopback Test – A diagnostic test in which a random data pattern is
sent down to an adapter link port. The data goes out the port and immediately
returns via a loopback connector. The returned data is subsequently validated
for integrity.
Note: You cannot run the External Loopback test and ECHO test concurrently. If you
select External Loopback the ECHO test section is disabled and vice versa.
Error Action
Enables you to define what is to be done in the event of a test failure. There are two
error action options:
Stop Test – Do not log the error and abort the test. No further tests are run.
Ignore – Log the error and proceed with the next test cycle.
Test Cycles
Enables you to specify test cycles three ways:
Select an established cycle count by clicking on the corresponding radio button.
Enter a custom cycle count in the blank field in the Test Cycles area.
Set the test to run until you manually click Stop Test, by selecting the Infinite
radio button.
Test Pattern
Enter a custom test pattern to be used in tests that transfer data. The test pattern can be
up to 8 hexadecimal bytes.
Test Status
The Test Status area displays how many completed cycles of each test ran, as well as the
number of errors.
To run loopback tests:
1. From the discovery-tree, select the adapter port on which you want to run the
Loopback Test.
