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.

Will update your forum thread with results once figured out.

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.

    That sounds really backwards compared to most gear I'm familiar with.

        I have a question while we are on the topic:  what color is
the last LED on your 450i AP when it is running at 1000 Mbps? I know it’s green at 100 Mbps, but what about 1000 Mbps? I
        know the user guide says orange, but is that what your AP
        actually does?

        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 ……….
