Re: [AFMUG] Gigabit Ethernet on Cambium 450i only running 100Mbps

[George Skorup]

I've seen less than 20 Canopy radios bad out of the box. Ever. Out of 
~3k over the years. Shit happens. They replace them.

Considering the cost of the 450 AP or SM, I don't see how you're so 
relaxed about that, compared to the quality control on a $120 ATX 
motherboard, which is a significantly more complicated PCB than any 
450... I know I've never unboxed one and had pieces rattling around 
even on the very cheapest.

    FYI, I got a couple 450 APs (not 450i's) with busted LEDs. One the
    power LED simply doesn't light up. The other one is one of the GPS
    or session LEDs. Both seemed to work fine, so we said screw it and
    installed.

    Then we got a new 5GHz 450 SM that wouldn't power up. Tweak the
    cable just right and it would come on. I suspect a bad solder
    joint on the RJ45. And a new 3GHz SM had a component rattling
    around inside. Small surface mount ceramic cap or resistor fell out.

    This is probably out of the hundred or so we've bought so far this
    year. Not a very high out of box defective rate at all. Just
    wanted to mention it. The pessimist in me says they're having some
    soldering problems in Mexico. But what do I know.

    No, the reason I’m asking is I’m seeing the LED totally off when
    running at 1000 Mbps.  Not orange like the user guide says.  What
    I am seeing on the actual AP is:

    10M: red

    100M: green

    1000M: off, nothing, nada, zilch, dark, devoid of visible radiation

    It really screwed me up because I thought there was no link,
    until I realized it was working fine at 1000FDX and reporting
    1000FDX in the GUI.

    I've seen this a lot - the Intel 1000BaseT server NICs all use
    yellow-orange for an active 1000Mbps link, and green for 100Mbps.
    Seems counter intuitive but it is sort of a 'standard'.

    Such as the i350-T2 and others.

            I am only catching part of this thread so dont throw
            anything at me for not reading the whole thread.
            450i radios are rated for the 56v unlike the 450 radios
            they are rated for cambium std 29v
            This is the reason I am having to upgrade all of my boxes
            to 48v plant as its base supply.

                Thanks for having a look at this for us.  It sure
                doesn’t make sense to me.  The system continues to
                run 1000Base-T Full Duplex here with the Cambium
                units.  I’m sure there is a reason but it looks like
                this one’s above my pay grade.

                No Joy. Everything checks out 100%.

                I bought one the cambium units for comparison. Its
                impulse breakdown voltage is about 5 volts to ground
                lower than my unit for single pin to ground.
                Transverse impulses are clamped much lower on the
                cambium unit but normally that is not an issue.

                Pin to pin and pin to ground I have less capacitive
                loading than the cambium unit.

                They have some other circuitry that I have yet to
                puzzle out.

                Something that is not related to surge suppression.

                In any event, your unit, a brand new unit from my
                stock and the cambium unit all show 1Gbps on the
                traffic tester and all show good wiring continuity
                and all show good breakdown voltage pin to ground.
                Visual inspections are not revealing any solder
                bridges or manufacturing issues....

                A puzzle for certain. But I am not finished. Stay
                tuned...

                  We’re not able to get our Cambium 450i radio’s
                  Ethernet Interface to run at Gigabit speed.


                  Our setup is as follows:


                  Gigabit switch (Tried several brands) à14’ Cat6
                  Patch àGigabit Sync injector (48V) à35’
                  Best-tronics Cat5 Shielded à800-800-GIGE-APC-HV
                  à80’ Best-tronics Cat5 Shielded àCambium 450i


                  It works without the 800-800-GIGE-APC-HV. (Cat5
                  Coupler).


                  Anyone ……….
