Running Diagnostic Tests

The Diagnostic Tests option on the Diagnostics tab lets you check the state of the physical components on a
Broadcom network adapter. You can trigger the tests manually, or choose to have BACS 3 continuously perform
them. If the test are performed continuously, then the number of passes and fails in the Result field for each test
increments every time the tests are performed. For example, if a test is performed four times and there are no
fails, the value in the Result field for that test is 4/0. However, if there were 3 passes and 1 fail, the value in the
Result field is 3/1.
Notes:
• You must have administrator privileges to run diagnostic tests.
• The network connection is temporarily lost while these tests are running.
• Not all Broadcom adapters support each test.
To run the diagnostic tests once
1. Click the name of the adapter to test in the Explorer View pane and select the Diagnostics tab.
2. From the Select a test to run list, select Diagnostic Tests.
3. Select the diagnostic tests you want to run. Click Select All to select all tests or Clear All to clear all test
selections.
4. Select the number of times to run the tests from Number of loops.
5. Click Run test(s).
6. In the error message window that warns of the network connection being temporarily interrupted, click Yes.
The results are displayed in the Result field for each test.
