Installed my first RB5009UPr+S+IN yesterday.
Picked this one as it shows a 130Watt power budget for devices.
Since this is pretty small install... Picked this unit to drive 3 Cambium XV2-21X. These are pretty small APs and have a max power draw of 13 watts each.
Units keep rebooting and I can't get anything from the APs. They rebooted because the power stopped.
In throwing s--t at the wall to see what sticks...
We turned off LLDP on the Cambiums. That lessened the reboots.
The next step is we turned down the transmit power of the 2.4 radios. That stopped the rebooting.
I sent a support file to Mikrotik last night before we turned down the power on the radios. But I don't think I will hear back from Mikrotik anytime soon.
Anyone else seen similar issues?
What are you guys driving with this unit's POE?
Re: RB5009UPr+S+IN power problems?
I have one that powers an AP (grandstream gwn7664) and a sip phone. The AP pulls about 8-11W and the phone around 3W during normal operation. My other 5 APs(same as above) are powered by a crs318 (netpower 16).
I have not seen any reboot issues.

Re: RB5009UPr+S+IN power problems?
Since turning down the power on the WAPS.... the rebooting stopped.
After 36 hours we increased the power by 3dB. Units are still stable.
Received an email from Mikrotik support this morning asking about the enabling POE logging.
/system logging add topics=poe-out
And to send a support file once the reboots return.
No reference too looking at the support file I already sent.

Have you tried forcing the POE on?

Re: RB5009UPr+S+IN power problems?
Support confirmed.
The Power Supply that comes in the box DOES NOT HIT THE SPECS HERE
https://mikrotik.com/product/rb5009upr_s_in
The 48V2A96W will provide up to 20 watts per port up to power budget.
However... the router itself could use 14-25 watts depending on attachments. (USB/SFP+/etc)
The router can run at up to 150watts. But that requires a different power supply.
Mikrotik does not make an indoor power supply for this. But they confirmed I could use this OUTDOOR supply to drive the router and POE ports to 25 watts.

Re: RB5009UPr+S+IN power problems?
Still the math is not right.
48v2A96W should provide 96 W.
96W - 25W (max RB5009 declared consumption)=71W
3x13W=39W
71W>39W
Maybe the AP's are not 13W each?
And also more than 48x0.42A=20,16=20W that a port should provide, as 3x20=60W still less than the theoretically available 71W?

We set the power lower in the radios and the WAPs are staying down below 10watts. And not rebooting.
When the CSS610-8P is installed... I will set the power to full and see what switch OS reads back to us.

CSS610-8P went in this morning. Logged in to the access points and cranked them up to full power.
No reboots.
Customer is happy.
Putting the RB5009UP into the "Do not order column".

There are fixes in Both 7.14
*) poe-out - driver optimization for AF/AT controlled boards;
and 7.15beta6
*) poe-out - improved firmware upgrade stability for AF/AT controlled boards;

Cambium tech has the RB5009UP on his bench. Sure enough... XV2-21Xs still randomly reboot.
Mikrotik has asked for logs and we provided them.

Mikrotik has "grasped for the straws"
LLDP on the POE ports
Have to go into the testing branch. Will report back.
