Sonicwall to Cisco 1700 connection problem - Amber light

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?

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

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.
