Testing the Router Module
To run a self-test of the router module:
1.Do any of the following:
∙Power the hub off and on.
∙Press and release the Reset button on the hub’s front panel.
∙Press and release the Reset button on the router module’s cover plate (see figure 3-2 on page 3-4).
2.Check the LEDs on the router module’s cover plate (see figure 3-1 on page 3-2).
If the Self-test LED has not turned off within 60 seconds after powering the hub off and on or after pressing and releasing the hub’s Reset button, or within 20 seconds after pressing and releasing the router module’s Reset button, the self-test has failed. Other LEDs on the router module’s cover plate indicate the nature of the error; to interpret the error conditions indicated by these LEDs, refer to table 4-1, “LED Error Patterns at End of Power-On or Reset Self-Test” (page 4-3 ).
The self-test does not test the router module’s ports. To test the WAN port, use the procedure on the next page.
