Power issues not withstanding, as aaa mentioned, those cards get hot, really hot. I don’t doubt that they can handle it, however, stacking them on top of each other is going to push it.
Also comes down to issues I’ve had recently of the radios interfering with each other. It gets pretty interesting running two cards in 2.4 and two in 5GHz on the same RB.
Depending on how my tower install goes in a couple weeks, my next will have a 411 for the feed and a 433 with 2.4 and 5 AP.
My current towers with loaded 600’s, 2x 5GHz ptp shots, 2GHz and an extra, 5GHz interferes with each other unless the signal is really high.
How does this interference show? Where do you see that
you have interference?
I have one RB600 installation with 4 r52n cards and I haven’t noticed any interference.
As to my question about the RB800 installation I’ve been running it in my office with
TCP Bandwithtest and 100%CPU on two cards and it gets warm, but not too bad. The Health Temp is
steady at 64°C
I’m not stacking the cards, but use 2cards on the RB800 and 3 on the RB604 extention
I’m using a an aluminum box and maybe it’s better with transfer the heat?
On my tower, RB600 w/4 R52H, 2 5GHz ptp, 2 backup cards, the two ptp radios show a significant drop in CCQ during load.
I am on tower two, tower three is the one in question, tower four is the last in line.
If I do a bandwidth test or any other load across from T1 to T2, everything is fine. If I load from T2 to T3, everything is fine. If I go from T1 through T2 to T3, T2 shows pretty nasty CCQ on the RX of both radios.
The physical separation of the radios by using the daughtercard helps, using the R52Hn with MMCX helps, may just be the N cards in general (no diversity switch), could be the MMCX connectors are better than ufl.
I have noticed that the N cards are better about self interference than the previous cards, and I’ve had less issues with the XR5 myself.
