POE Compability?

Dear all,

i bought a heX POE to manage connect and power via POE my SXTsq 5 ac and a RBwAPG-5HacT2HnD, as per manuals :

RB960PGS can power 802.3af/at devices if 48V DC input is used (unit comes with 24v power supply,so you would have to purchase 48v power supply separately to support this). Unit provides maxcurrent 450mA for each port regardless device power class (doesn’t support PoE powered device classification).

so because of the non linked power supply i baught the FLD0716-48 to meet the 802.3af/at. now i will connect all but nothing happens.

i checked the interface POE status which is still “waiting for load”, with the passive poe adapter the devices are working.

Greetings

Specifications of SXTsq5 ac define powering voltage between 10 and 28 V. Implicitly this means that this device can not take 802.3af PoE (which is specced at 48V), it rather uses proprietary passive PoE (which RB960PGS can do if powered with supplied 24V power adapter).

Specifications for wAP ac say that powering voltage is between 11 and 57 V and that it takes (also) 802.3af/at power source. However, it is also true that it takes passive PoE as provided by RB960PGS if powered with 24V power adapter.

Which means that if you use 48V power adapter to power RB960PGS, wAP should start while SXT would not. If you use power adapter that came with RB960PGS, all three devices should start.
One thing that might interfere is use of long UTP cables between RB960PGS and auxiliary devices … which might make RB960PGS to sense some anomaly on PoE or another, such as short.

Hi mkx,

thx a lot for this explanation, this helpted me a lot. Now all is fine and working.

Thx
