Diagnostic Tests

Testing the Router Only

Use one of the initialization procedures listed below. Both include a self- test of the router’s internal circuitry. For the other effects of these proce- dures, refer to “Initialization Sequence” (page 2-19). (Neither tests the router’s ports; refer to the next section for port-testing information.)

1.Cycle power on the router by unplugging the power cord and then plugging it in.

2.Press and release the Reset button on the back of the router.

If you see any of the following results for either test, take the indicated action:

If the Power LED does not light, the router is faulty; replace the router.

If the Self-test LED does not light and then turn off after one to three minutes, the router is faulty. If you have tried to change the product operating code or have access to the code on another HP router, try updating it again. If not, then replace the router.

If the Fault LED lights, look up the pattern of LEDs in table 3-1 on page 3-2, and follow the instructions in that table.
