Sonicwall to Cisco 1700 connection problem - Amber light

Hi,
Previously I had my Sonicwall NSA 3500 connected to our Cisco 1700 series router and things were working fine.  I unplugged the temporary cable connecting the two of them and ran a new one from the Sonicwall in our racks across a cable management system to the 1700.  Now on the Sonicwall, I only am getting an amber light, which blinks occasionally.  The link status on the NSA is reporting "10 Mbps half-duplex."  It is set to auto-sense the speed.

Out of desperation I tried switching with a known good cable, still the same result.
With both cables, I was able to plug into my laptop, give it the right IP address info and make it out to the internet.

Any guesses?

ARe you using a straight through cable as your known good cable? will not work , you need a crossover cable, the firewall and the router are like devices.

I've tried a stright-thru and crossover so far, both with the same results.  Right now it is a crossover.

Look for errors onthe interfaces, checksums, FCS, input and output, could be a interface went bad.

Do a sh interface X where X is the interface.
This will list all errors as well as speed and duplex info and link/protocol state.
Please post this.

Hmmm well that doesn't really give much info compared to the Cisco readout. Is there some way you can view the interface statistics?
