I currently have 3 DVRs running off of an SWM8 switch. An HR21/700 and a HR20/100 running on standard SWM8 ports and a R15/500 running off two legacy ports. I just ordered a HR34 that is going to replace the HR20/100. With the HR34 using 5 ports I'm concerned that I now have too many (9) connections on one switch. Do the two legacy ports for the R15/500 count towards the 8 total ports or is that a separate count?
