If you don't want to change any router settings, you could find a small hub or switch (one that's not built into a router), plug the blade into it, and plug a PC's ethernet port into it. On the PC, change its IP address to a static address of 192.168.1.1,
netmask 255.255.255.0. The DNS setting won't matter.

Then, fire up your PC web browser, and point it to http://192.168.1.254:8000. You can then use the web interface to change your blade's IP address to match your router's LAN addresses.

If you have a crossover ethernet cable, you might be able to connect a PC's ethernet port directly to the blade, without using a hub or switch.
