1st Day
I download all manual from http://www.routerboard.com and read it
I download all manual from http://www.mikrotik.com and read it
I setup the jumper to use a POE
I insert the ubiquity SR2 at 532A routerboard
I conect the 532A routerboard POE with a 9V adapter(i have)
I connect to the 532A with a null modem cable and is ok
I download from mikrotik routeros 2.9.4 upgrade files
I upgrade the 532A routerOS to 2.9.4 and is OK
I setup the 532A and is ok
I connect it to internet and is OK
I share internet over Ethernet ports and is ok
BUT
I try to setup my SR2 and isn’t function
because the SR2 is NOT in a device list
I shutdown 532A
then i insert the sr2 in back side of 532A and turn on
532A is ok
but the SR2 is NOT in a device list
then i shutdown the 532A
I have used for two days OK but with out SR2
I read the manual again to try setup SR2 again
3rd day

the routerboard is not OK
and sometimes turn on and orange led lights on (not the blue)

is 9v enough for sr2 ?

I doubt it. You should go with a higher voltage power supply. I use 15v 1.2 amp on cable runs of less than 75 feet and they work well.
