Testing the Router Only

To perform a self-test of the router's internal circuitry, switch the power
on and off. (For details regarding what happens when the power is
switched on, refer to "Initialization Sequence," page 2-15.)
To diagnose a failure that occurs during the power-on self-test, refer to
table 3-1; to diagnose a failure that occurs during router operation, refer
to table 3-2.
The power-on self-test does not test the ports on the interface cards.
Information about testing the ports on an interface card is provided in
the card's documentation.
