Hi All,
I’ve gone through the rather simplistic examples that Rockwell has for PRP and cannot answer the question below. ETAPS are listed as supporting DLR only … but if I am using them as protocol converters from copper to fiber … and there is only 1 of the 2 DLR ports used .. I think that it maybe does not make a difference? UNLESS there is something goofy about PRP that uses larger IP frames than the ETAP can deal with .. or something else that I have not even thought of.
Given that introduction .. I have ETAP and PRP questions. Our local Rockwell network people are apparently very busy and are not getting back to me in a reasonable time.
SOOOOOO … I’m asking here!
I am looking for ‘NO, it won’t work because …’ or maybe I’m looking for no one to tell me it won’t work. It would be awesome if someone posts ‘YES, this works’ ..
The attached sketch is out of date (IP addresses will not be routable, Uplink interfaces look a bit different), but it shows the general idea. We have a PLC with 3 local racks (inside an MCC room) and a remote rack (in another building). The local racks are on PRP to redundant Stratix switches. Each stratix then communications to multiple redboxes and then on to the cisco switch stacks that the IT guys deal with.
The ETAPS on each Stratix to the EN2TP in the DOZER are where my question is. Can I use the ETAP1F or ETAP2F as a media converter only, and have that take my PRP off cat5 to multi-mode fiber and back to cat5 so that it can connect to each of the Stratix switches? I’d prefer to stay with all rockwell branded stuff so that we don’t have rockwell tech support pointing to equipment from another vendor (blackbox, etc) as the source of a problem when we are troubleshooting.
Is anyone successfully using another brand of media converter instead of an ETAP on a PRP network?
If this is not a valid configuration, we can make things more complicated and use the ETAPS in a DLR that only goes between the processor rack and the Dozer shack. But I think it is easier to explain what is happening with everything on PRP.
