Management Ethernet port

The management Ethernet port is a 10Base-T/100Base-TX/1000Base-T autosensing RJ-45 port. It allows you to upgrade software and manage the router through a network management server without using any service interface of the router. The management Ethernet port is used only for managing the router and it has no service processing capabilities such as data forwarding.

Reset button

CAUTION:

•If you perform no save operation before resetting the router, the current system configuration will be lost.

•Never press the RESET button when the RUN LED is flashing fast or when the router is accessing the CF card or a USB storage device. Otherwise, the file system of the router might be damaged.

To reset the current MPU, press the RESET button.

{If you press the RESET button when only one MPU is equipped, the whole system will be reset.

{To perform an active/standby switchover when two MPUs are equipped, press the RESET button on the active MPU. The system automatically switches the services to the standby MPU, without interrupting the ongoing services.

{If you press the RESET button on the standby MPU when two MPUs are equipped, the standby MPU will be reset but the system operation will not be affected.

The RUN LED goes off when the MPU is reset, flashes fast (at 8 Hz) when BootWare is running, and flashes slowly (at 1 Hz) after the system is booted and operates correctly.
