I have read several forum threads and I'm still a bit confused about connecting one Nanostation to another. Here is what I would like to do:
Right now I have a hAP in the house with cable running to the roof connected to the main port of a Nanostation M2 (via the hAP DTD port) with POE supply in-line. I also have a Nanostation M5 on the roof (off-line right now) and would like to connect the M5 to the M2 vice running a second cable to the roof (I don't like ladders).
My questions are:
1. Can I power the M5 from the M2 if I enable to POE pass-thorugh? If so, is this advisable?
2. Does the secondary port of the Nanostation function as a DTD port? If so, should the cable from the secondary port of the M2 Nanostation be connected to the main or secondary port of the M5.
3. Assuming all of this can be done (above) will having two series DTD connections degrade overall performance?
Thanks in advance.

yes. This is a very handy feature. It is only not-advisable if the max current of the POE pass through is exceed (which I don't see in the manufacture specs). the max current is probably found in the Ubiquiti forums or with a Ubiquiti support request. Use 24v to maximize the power that the POE Passthrough can provide. I've daisy chained 2 devices power supply->NSM5->NSM2->ipCam with 24v. The ipCam had a 24v->12v POE splitter. This worked fine, and had to have a better power supply than came with the NS -- the ipcam would reboot not getting enough power.
"Does the secondary port of the Nanostation function as a DTD port? If so, should the cable from the secondary port of the M2 Nanostation be connected to the main or secondary port of the M5."
Yes. (but trying to remember if these features came before 3.19.3.0 or after, but certainly in the nightly build images.) All ports on the Nanostations are identical with LAN, WAN, and DtDlink network functionality. Think of the network as if it was a one port device with a dump switch attached. Because the 1st node in the daisy chain boots first, all the LAN IP addresses end up being assigned from this node, even if connected to the 2nd daisy chain node's secondary port -- don't have to turn off LAN DHCP on the 2nd node.
"Assuming all of this can be done (above) will having two series DTD connections degrade overall performance?"
No. this is within the capabilities of the nodes. The bottle neck is the RF link rates, which is only 65Mbps max in 10MHz channel generally used compared to 100Mbps cat5 data rate.
Thanks for the fast and thorough response. Up the ladder I go.
