I have an upgrade scheduled for Friday but still have a couple of questions that I haven't seen answered (but I might have missed it in the deluge). I have a current system with 2 HR21-700's and 2 H21's (1 -100 & 1 -200) so everything appears SWiM & DECA compatible. I currently have the 4 RG6 lines coming from the dish to a x8 powered multiswitch with 2 RG6 coax to each box (all homerun) and a cat 5e to each of the 4 boxes (also have a 3rd RG6 coax to a couple locations to provide OTA to a couple AM21's but this is separate and should remain separate). I have MRV running on the beta with manually assigned IP addresses and have selected and 'passed' the ports through my router for network services (if it gets used for something sooner or later). My questions. I assume that the LNB on my dish will be replaced with a SWiM LNB since this will provide the support for the six tuners needed. I also assume that they will probably then functionally replace the multiswitch with an 8 way splitter (don't think there is a x6) and use one of coax lines to a DECA at each unit (2 DVR & 2 receiver). Please correct any errors in my assumptions. Questions: 1. Does this configuration require 1 PI or 2? I see many comments that a PI is needed for SWiM and DECA. If the answer is 2, what location restrictions are there on the PI for SWiM? I believe that the PI for DECA would be handled by the 5th DECA that would be used to connect the DECA cloud to my network (this would be most convenient in my layout). 2. What has to be changed in the IP address assignment and port assignment and port passing for Network Services? Does the DECA cloud do a DHCP like assignment for communications with it's own subnet or will it use the manually assigned addresses currently used in each DVR/receiver? Fortunately, I won't get into the SWiM 16 availibility problems or the HR20 quirks but, after reading some of the installation descriptions, I feel a need to understand the installation requirements better than the typical installers to try to keep my blood pressure down. Any help will be greatly appreciated!
