Managed Switch and Patch Panel are above my skill level, compared to BR1GAND's
2008 diagram, I do recommend connecting ONE LAN Port of each Router to a Switch and leaving the rest unused. My logic is that since I've upgraded my LAN 'backbone' to Gigabit, I want to keep all 'Internal' LAN traffic away from my older 10/100Mbps Router (gave up the DSL) such that only 'External / Internet-Bound' traffic reaches it.
With several legacy 100Mbps devices still in service in 4 rooms (Media Streamers, ReplayTVs, Print Servers), I also run separate 10/100Mbps switches off 1 port of the Gigabit switches so that they can communicate with each other without 'wasting' multiple Gigabit ports.
When both tuners in 2 SiliconDust HDHR3-US units are feeding 4 channels to my Vista HTPC using WMC, ~60Mbps is only consuming ~6% of the available 1Gbps bandwidth according to Task Manager. --
