A one port PZ-BS11 card. It goes in the expansion chassis for an SV8100. Your main chassis will need to have the 3 port card (PZ-BS10) and must have the ME50 memory expansion installed or it won't recognize the new expansion shelf. You will also need a short Cat5 cable. You will probably need the 256 port expansion license as well.

Tested. 90 day warranty.
