Self-Test Progress States
Upon power up, the router immediately begins a sequence of self tests and
memory sizing. The following sequence of LEDs pass by so quickly that it is
difficult to identify the discrete steps on a functioning router.
Should a hardware fault be detected, the LEDs will reflect the progress made
into the self-test. This information can be useful when describing problems to
your service representative.
Table A-1 describes the router’s self-test progress LED states.
