Resetting the Router: The Reset Button
Using a non-conducting, pointed implement such as a wooden pencil or
a toothpick, press and release the recessed Reset button on the routing
engine. (See figure 2-6 on page 2-9.) Resetting does the following:
Lights all router , module, and port status LEDs while the Reset
button is pressed.
Runs a minimal self-test of the routing engine. During the test, the
Status LED for the router is orange, the Card LED for the routing
engine is orange, and the Self-test LED for the routing engine is
green.
Initializes (boots) the router, using the most recently saved
configuration.
Displays "Waiting for speed sense" on the console so you
can start a console session if needed. (Refer to "Plug in and verify
router hardware" on page 1-18.)
Switching the power off and then on resets the router as described
above, plus it performs a more extensive self-test. However, while
pressing the Reset button preserves the event log (which can be
displayed from the Main menu) and the crash history (which can be
displayed using NCL's Crash command), this information is lost when
you switch the power off and on.
For more information about resetting, see "Initialization Sequence" on
page 2-15.
Resetting does not affect any current password(s).
Any configuration changes you have not yet saved (in either Quick
Configuration or the Configuration Editor) are discarded. That is, the
router initializes with whatever configuration was last saved.
If the Status LED does not turn green within a couple of minutes after
pressing and releasing the Reset button, the self-test has failed. In this
case, check the Pwr, Fan, Temp, and Card LEDs for the error and refer
to chapter 3, "Troubleshooting."
