This is reality with the XR's. When I went to a 600a using a daughterboard for an AP, I mentioned I was using XR cards when I was talking to Mikrotik and they told me that the board would not be able to power all the ports if they were populated with XR cards. They draw too much power. I'm using a 48v on that one with 6 cards and I would guess the same type of issue would be with the 433AH and 411a. We use 19v on our 411s.

I was running 3- 411a boards with 12v they worked great for about a week then all the sudden the clients started all dropping off and back on. Then it started locking up ever night I got to the point that I made it part of my early morning coffee to drive the 15 miles and reboot every day. After 2 weeks of messing we realized that the units were struggling for power. We went to a 24V POE and that same tower has now been up with 40 clients for 165 days. The XR series really tasks the boards. That is what fixed it for me. I think those XR boards really eat the power.

It's the third long fix period I've had to do for Microtik this weekend, while I do have 20 AP's and backhauls under that brand, none work easily, and the frustrations are plentiful. SO Last week we upgraded a prizim chip to an XR2 on a three radio card 133c. We started to have problems with the new card randomly dropping then after disable/enable would come back up. As the week went on it happened more frequently. First solution, change out the new card, no difference. The next was a new power supply. Figured that was it since the 133 was running on a 12v, we upgraded to an 18iv, no change. So this weekend upgraded to a 433ah board and the three cards (2 XR2's and 1 SR1 as you know you can't put three XR2's in a 433 cause they made the slots too close together), no change, now the board wouldn't drop the connections it just increased latency dramatically after a few minutes, then resume low pings (average at this tower is 4ms) for about 50 cycles then get worse until about 4000 then time outs. Today after manually entering the 120 people on the new board (four hours since you can't cut/paste to a Microtik) the ethernet port dropped. I should point out I'm on my third trip up my steepest mountain where my jeep struggles to get up it. Power cycle and it's up (yes I'm well aware of remote reboot systems but its never been a problem so it was low priority). Tonight my after hours is slammed with "my Internet is so slow" calls from that tower and sure enough 4000ms pings. I've spent all weekend on it and I don't know what else to do, any ideas out there? I know these radio's pretty well so I've tried the simple stuff (adjust power, change frequencies, blah blah) HELP!
