If you also have a standard copper cable (or a second fibre cable) connecting the two switches (for resilience perhaps?), this issue is probably being caused by something called Spanning Tree. This is implemented on switches as a 'loop avoidance' system, and can look like you have described with one end 'ip' and the other end no lights.

On the Cisco switch, get to a telnet/ssh/console session, log in and enter show spanning-tree and press enter.

have a look to see if the fibre interface has a status (sts column) of BLK. If it has, then this is called 'blocking' and will remain like that until you remove the second link to the other switch.

Hope that this has helped!

I don't know anything about these units, nor do I have time to source any docs for you, but maybe you can try connecting a PC directly to the port your patch panel is connecting the the switch from, you can at least see if that port is working. My next and only other suggestion is to invest in a "LAN cable tester". In my area, you can find cheap ones for U$20. The tester will allow you to check connectivity between any two ports, and allows you to test both patch links and individual CAT5/6 cables. Good luck!
