Hi Gents, Thank you for the advice. However, I only used SIP as an example. It would still work however, since I could/would check the IP address on first registration. What I'm looking for here is a live dynamic solution that is not primarily based on address lists but on a reply from an IP address...

siscom

Hi,

Really? Never heard of that ....

So running a service eg a SIP gateway behind a Mikrotik router does not mean you have to accept externally originating traffic??
That's what I need to check - incoming connections via their IP address ...

Cheers,
Mark.

siscom

Hi All, Has anybody tried to use scripting or some other method to check incoming IP connections (globally or to certain services only) for reputation by an external provider like https://scamalytics.com/?

Hi rgraham,

Just putting/placing the voltage meter on the 3.3vDC jumper probably will not be much help. You need to place an amp meter in line to see the current being draw in Amps and not the voltage in Volts.

Hope that helps,

siscom

Hi rgraham, In a DC watts to amps conversion, the current I in amps (A) is equal to the power P in watts (W) when divided by the voltage V in volts (V), i.e. I(A) = P(W) / V(V). So in your case you are right, it is 3.03Amps approx. Did you get a spec sheet with the convertors? It might give you the ...

Hi Sigma,

Depends on what you are expecting the unit to do.

Is it just for AAA or shall you then be doing mangling, queuing .... ?

If you think €260 is expensive, the CHEAPEST flight from Malta to Zagreb on those dates (12 to 16), excluding any additional taxes, is €525 and that involves a stop of about 6hrs via Frankfurt each leg and a plane change.

Hi, You can replace the faulty ones with ones of the same specification. The important bit is '560 uf, 6.3 volts' We had to replace quite a few (RB750 and RB450) and never had a problem finding the parts. Any decent electronics shop should have them. If not, you could try the RS catalogue online at ...

Hi, We seem to be also having problems with RB750 units that seem to have ceramic type capacitors.

Hi, It would be useful to know what your clients are going to have on their side of the link. Are the units going to be regular, SISO or MIMO units? Are you going to supply the CPE yourself?

Hi, With us, this problem was actually the angle of the antennas with the double glazed glass. We checked on the gas and since this is 'inert' it should not be the problem.

Hi, I've actually used what you are pointing to (UBTik).

Hi Alex, I have always supplied our RB600 boards power via Extreme Switches with PoE at both Datacenter and remote locations. So unfortunately, I cannot point you to a power supply model.

siscom

Hi, The RB600 can pull a max of 35w and at 48v that would be approx 0.8A 1 x R52Hn is max 7W; 3 x R52 at 2.4W each is 7.2W; 1 x CM9 is max 0.5W. So all cards (in Theory) at max could draw approx 4.4Amps (using P=I x V) and at 3.3vDC This, to me, means you might really need to get a higher rated powe...

siscom

Hi Alex, Could be a question of watts or amps and not volts. You might check how many watts the radio cards pull as a maximum (in total) and then replace the power supply with one which should be slightly over rated. Also, if you hava a long PoE cable run, this might also cause voltage drops. Rgds, ...

My feelings exactly.

We install these mostly on outdoor AP units and that means we regularly get 45 Deg C temperatures on them - externally.
