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.
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).
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. https://mikrotik.com/product/mtp250_53v47_od
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?
Which frimware were you on?
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;
