If the automatic speed sensing does not connect your console and give
you the router's copyright and Main menu screens, as described under
"Connect a console" (page 1-14), then try the "Reset speed sensing,"
Adjust baud rate," and "Reset the terminal" procedures (pages 3-14
through 3-15) in sequence.
If none of those procedures result in proper console access:
1. Check the LEDs (refer to "Interpreting LED Error Patterns," page
3-3).
2. If the LEDs appear to be normal, the routing engine is faulty.
Reset speed sensing:
1. Detach the console cable from the router.
2. Reattach the console cable to the router.
3. Look for the line of text on your console that indicates waiting for
speed sensing; then press [Return] to display the copyright screen or
the Main menu screen. If neither of these screens appears, press
[Return] again. If pressing [Return] four or five times does not display
either the copyright or Main menu screen, go on to "Adjust Baud
Rate" below.
Adjust baud rate:
1. Temporarily set the baud rate of the terminal or terminal emulator to
9600, if available, or to the slowest setting.
2. Detach the console cable from the router.
3. Reattach the console cable to the router.
4. Look for the line of text on your console that indicates waiting for
speed sensing; then press [Return] to display the copyright screen or
the Main menu screen. If neither of these screens appears, press
