cisco 2620 error

On a new recently installed 2620 i have encountered a problem, any traffic through the fastethernet module - in or out - causes the router to re-boot with a segmentV exception.

The router has a single network module with a wan card installed on it, the wan card has been tested and works fine.

It seems that this is usually caused by a software bug and that updating the software is often the answer ( this router is also running an early release deployment) if this is the case how do you upgrade the ios when the only ethernet port will not accept any traffic.

I have attached some info at the bottom.

Any help would be appreciated.

Re: cisco 2620 error

The Output Interpreter confirms that it is a software failure. If you want to upgrade the router, you can try upgrading across the serial interface if you have another to "back-to-back" it with. Apart from that, your options are limited. You could Xmodem through the console using ROMMON but it will take a while.

You may want to try the FE mod in a different slot.

Deilert - The Fast Ethernet on a 2620 is on-board. There are two spare WIC slots and one full-sized NM slot.
