Vonage customers, how do I add the RT31P2 into my network?

I have a network that consists of a Belkin Wireless Router f5d7230-4 attached to a Netgear 8 port switch. The Netgear is using the uplink port on itsef to go to the Belkin router.

The Linksys RT31P2 has 3 LAN ports so I need to run one of them into the Belkin witch does not have an uplink port. Am I correct in assuming I just need a crossover cable for this?
