Out of the box the unit should have DHCP enabled on FastEthernet Ports 0 - 3 with a subnet of 10.10.10.0 /24, FastEthernet 4 being the WAN interface is shutdown by default.
You will need a patch cable to do the job, my advice would be to ask if you have tried plugging into all the ports? Failing that you will have to find a terminal with a serial port.
