Instructions
Plug a standard Ethernet cable into the "LAN connector" port on the back of the first Playstation 3.
Plug the other end of the cable into one of the numbered ports on a router, switch or hub. Note that the router, switch or hub does not have to have an active Internet connection.
Connect a second Ethernet cable from the "LAN connector" port on the back of the second Playstation 3 to a different numbered port on the router, switch or hub.
Plug the router, switch or hub power supply into a wall outlet.
Insert the same game into each of the PS3 systems and start both systems. Note that each PS3 must connect to a separate television and you must have two copies of the game.
Locate the game option for "System Link Play" or "LAN Play" from the main menu of the game. Select the option on both PS3 systems.
