The diagnostic tests are:
• Online—A non-disruptive test that exercises port-to-device connections for all ports on a switch that are
currently online except for TR ports, which are not included in Online Switch Diagnostics.
• Offline—A disruptive test that exercises all port connections for a switch in the diagnostics state. When
you run an offline test, the switch automatically enters the diagnostics state, and does not return to its
original state until the Switch Diagnostics dialog box closes. A disruptive switch reset must be done at
that time to return the switch to its original state.
• Connectivity—A disruptive test that exercises all port and inter-port connections for a switch in the
diagnostics state. When you run a connectivity test, the switch automatically enters the diagnostics
state, and does not returned to its original state until the Switch Diagnostics dialog box closes. A
disruptive switch reset must be done at that time to return the switch to its original state. The two types of
connectivity tests are internal loopback and external loopback.
To test a switch:
1. Open the faceplate display of the switch to be tested.
2. Open the Switch menu and select Switch Diagnostics, and then select Online Switch Diagnostics or
Offline Switch Diagnostics to open the Switch Diagnostics dialog box.
3. Select the test type from the drop-down list.
CAUTION: If you selected the Offline Switch Diagnostics option, the test type options, Offline and
Connectivity, disrupt traffic. When you run an Offline or Connectivity test, the switch automatically
enters the diagnostics state, and the switch does not return to its original state until you close the
Switch Diagnostics dialog box. A disruptive switch reset must be done at that time to return the
switch to its original state. If you selected the Online Switch Diagnostics option to run the online
switch test and there are no ports with an active login at that time, the test returns immediately with
a Passed status.
4. Enter a frame size in the Frame Size field.
5. Enable or disable the Terminate Test Upon Error option.
6. Select a Loop Count option. The Loop Forever option runs the test until you click Stop Test. The Loop
Count option runs the test the number of times you entered in the Loop Count field.
7. Select the default test pattern or enter a user-defined (hexadecimal) test pattern.
8. Click Start Test to begin the next test, or click Close to close the Switch Diagnostics dialog box.
Observe the results in the Test Results area. If the Test Status field in the Test Results area indicates
Failed, note the Test Fault Code displayed in the Switch Information data window and contact Tech
Support.
