C H A P T E R 8 Console Port Use and Troubleshooting

Important considerations

To enter Maintenance Mode

BOOTP request and the name of the boot software to a specified boot server. This is useful if the boot server being used does not support the use of a bootptab file.

•It runs tests on hardware and provides diagnostic information.

Note Loading software to the switch in Maintenance Mode should only be done as a last resort. This is because the soft- ware and configuration already resident in the flash memory is overwritten and lost.

Consider these points when using Maintenance Mode:

•The switch is not operational and the expansion board ports can- not be used.

•Only simple command-line access is possible via the Console port.

•There is a delay before you see the command prompt; this is due to a hardware test routine being completed.

To enter Maintenance Mode:

1Using a pointed tool — such as a bent paper clip, press the Reset button on the front of the switch and hold it until the SYSTEM LED flashes green quickly (five times per second).

2Release the Reset button.

3Attach a VT100-compatible terminal to the serial port on the front panel using the cable supplied.

4To display the command prompt on screen, press the Enter key a couple of times.
