Regarding cable

That makes since. We really like the Arc wireless cable because it meets the 
need for 70% of the CPE side installs (residential and small business) with 
ease of use and the right price. The industry really needed a product like 
that.  But the ARC cable is what it is, and is no substitution for high 
grade cable when it is needed.  The Superior Essex we use now, has been 
proven to be awesome. We use it the other 25% of the time, when we have long 
runs or have to extend across gravel flat roof (where there is risk it will 
be submerged in water or walked on.). Many don't realize that it is not just 
the metal shielding that gives isolation from interference (environmental or 
self induced crosstalk). The non-metalic outer jacket and inner jacket of 
the wires also have isolating characteristics that contribute. There is 
something to be said for total thickness of a cable.

Good points.  Likely I will not touch it again unless it breaks.  I'll try 
to get a make on the good cable, but I know the cheap stuff I ran 
yesterday is the arc wireless shielded, flooded, drainwire, I picked up 6 
months ago when it was $69 a roll.

So the question that arises, is why did that fix it?

I see two possibilities

1) Poor quality cable or cable shields. (Loss running Ethernet data 
parallel to power)

2) Sharing a CAT5 jack on the 532 main board for Power and Data.

Travis previously talked about the horrid RF interferrence that the 532 
board generated when using 48V, due to the 532 onboard power 
converter/supply.  I'm wondering if the distortion/loss was at the board 
itself apposed to cable?


It would have been interesting to know, if you used one cable for both 
data and power, but terminated the data pairs to a different Ethernet 
port instead of the POE port used for power.


What also would have been interesting would have been to know wether a 
18V power supply would have worked on a shared single cable.


Different ethernet chipsets do have different characteristics and ranges. 
So it is possible that just the different chip made the difference based 
on compatibilty or characteristics of chip.  But the other reasons are 
just as probable.


What brand (not just shield type) cable were you using? I realize that 
you would not likely pursue additional tests as you found a fix already, 
but it would be interesting to know, just so we can keep collecting data 
should we experience similar problems in the future.


We had a similar situation that was due to chipset. We ran 10 mbps 
ethernet 550 feet to our subscriber. (different radio brand).  We used a 
slightly higher power voltage to make up for cable loss.  Our laptops 
worked great over the link.  The customer's 3 identical routers could not 
stay connected for long. We were not sure if it was a speed autodetection 
issue, or the distance for the chip to work.  We installed a 10mbps Cisco 
Switch in between their router and our cable dmarc in their premise, and 
it all worked.

I started with   RB 532 on tower.  It comes down 265 feet to poe 
injector to router.  Major packet loss.

2)  switched RB 532 out.  No change.
3)  Created test setup on ground with bad board and it looked fine. 
(from laptop--6ft cablepoe265 ft---RB)

4) Blamed it on the cable, and got a cable certifier from a friend.
5)  Right before climb, I re did the test setup on the ground.  This 
time I plugged the 265 feet into the actual router instead of my laptop. 
The problen was back.  (I was bummed)
6)  One final test.  Get another 265 foot cable.  I used 265ft for power 
and 265ft for data to eth 2 or 3. Problem solved. I can only speculate 
that the chipset on RB 532 poe port is diffrent from the chipset on eth 
2/3.
And for whatever reason it was not compatable with cable, hardware, 
ect.setup.
I may never know for sure why, but I have the workaround.  Good enough 
for me.


FWIW  I ended up pulling 2 new cables (all 3 certified fine).  I used 
the original cable for data (it has real shield)  I used my new 2 
(cheapo foil shield) for power and slapped the other into eth3 for the 
heck of it.


Lessons learned for next time. Measure cable, crimp, and power up on 
ground using the EXACT same everything as what the final deployment will 
have.  And then test.


Hope that sums it all up.

Couldn't find it.  Under cable settings is default, standard, and 
short.  From the manual it looks like default = long cable and it 
looks like default is the default.

But I have no idea how to see what mode it is on.

I was on 48v from the start.  But I tested 4 48v power supplies300, 
420, 700, and 1000mA units.  None of that had any effect.


The seperate cables.  One for power, one for data fixed it.

That is why you see transformers all over the place.

I like 48 Volts a whole lot more than 24 volts.

I ran another cat5 up the tower and plugged it into the RB 532. 
 

Now I have one cable for poe and one cable for data, and it all works fine.

Re: [WISPA] MT power supplies THE SOLUTION

2006-09-15 Thread Tom DeReggi



Additionally consider, just because something works 
on the ground doesn;t mean that it will work up in the air, for two 
reasons.

1) When operating outside of specs, it may take a 
period of time before the equipment starts to fail and flaws show 
up.
 (heat build up, or stress on 
devices)

2) Interferences stretched along the tower 
structure for 250 feet, may be different than interferences that exist in a coil 
at the ground.

Take note, that even though COILS can degrade 
signal,I've tested 500 feet cables on the ground in coils with Trango 
successfully, butup on a roof, failures at 200 feet in some 
circumstances.

So...

first, do the math.
second, test on ground.
third, prey that it will works after its been 
installed on the tower. :-)

The most important lesson, is to rule out unknowns 
before you install on the tower. 
Test IP configurations of radios from laptop. Use 
patch cables that will be used when testing live. Work with a set of 
knowns.
So you don't have to Climb just to rule something 
out. And always test before you climb down.

Good points.  Likely I will not touch it again unless it breaks.  I'll 
try to get a make on the good cable, but I know the cheap stuff I ran 
yesterday is the arc wireless shielded, flooded, drainwire, I picked up 
6 months ago when it was $69 a roll.

Tom DeReggi wrote:


So the question that arises, is why did that fix it?

I see two possibilities

1) Poor quality cable or cable shields. (Loss running Ethernet data 
parallel to power)

2) Sharing a CAT5 jack on the 532 main board for Power and Data.

Travis previously talked about the horrid RF interferrence that the 
532 board generated when using 48V, due to the 532 onboard power 
converter/supply.  I'm wondering if the distortion/loss was at the 
board itself apposed to cable?


It would have been interesting to know, if you used one cable for both 
data and power, but terminated the data pairs to a different Ethernet 
port instead of the POE port used for power.


What also would have been interesting would have been to know wether a 
18V power supply would have worked on a shared single cable.


Different ethernet chipsets do have different characteristics and 
ranges. So it is possible that just the different chip made the 
difference based on compatibilty or characteristics of chip.  But the 
other reasons are just as probable.


What brand (not just shield type) cable were you using? I realize that 
you would not likely pursue additional tests as you found a fix 
already, but it would be interesting to know, just so we can keep 
collecting data should we experience similar problems in the future.


We had a similar situation that was due to chipset. We ran 10 mbps 
ethernet 550 feet to our subscriber. (different radio brand).  We used 
a slightly higher power voltage to make up for cable loss.  Our 
laptops worked great over the link.  The customer's 3 identical 
routers could not stay connected for long. We were not sure if it was 
a speed autodetection issue, or the distance for the chip to work.  We 
installed a 10mbps Cisco Switch in between their router and our cable 
dmarc in their premise, and it all worked.

Good call Brian, Being an electrician all of my previous working life, 
voltage drop is a serious consideration at 300', even with 120 volts.
Solution has always been to increase the voltage to reduce the amperage 
to control voltage drop.


That is why you see transformers all over the place.

I like 48 Volts a whole lot more than 24 volts.

I have a fancy cable tester coming from a guy I know.  We'll see what it

The 800 to 1300mA consumption is at 3.3V.  The 700mA from the PS is at
48V so there is probably plenty of power going to it.

Is the CAT5 shielded?  What else is on the tower?

Re: [WISPA] MT power supplies

2006-09-13 Thread Brian Rohrbacher

Yes, ethernet is shielded.  The good stuff.  It's like almost 1/2 inch cat5.

The tower has pagers, lots of trango, few backhauls, canopy 900, and 
some more I believe.  The only thing up with me is some trango, and they 
have no problem.  I am pointing at a bad cable.

The 800 to 1300mA consumption is at 3.3V.  The 700mA from the PS is at

Is the CAT5 shielded?  What else is on the tower?

I am surprised no one has mentioned this. I looked up power consumption
on the SR5 and it shows 800 to 1300 mA each. You state your power supply
is 700mA. I did not look up power consumption for the RB532 but I would
think you would need at least a 3A supply.

So, does anyone know if it looks like I would be fine on the power side 
of things?

I have tweaked the ethernet port settings for no gain.

Next step is to get climbing 280ft to replace board, but I'd like to 
confirm power first.

I would check the terminations and maybe re-terminate them, especially
if you have verified with a new cable that it works ok.

RE: [WISPA] MT power supplies

2006-09-13 Thread Paul Hendry
When I say re-terminations I mean do you have a single cat5 cable from PoE
injector to RB532 or do you use any fly leads. Also, do you terminate the
outdoor cat5 to a connector on the AP then a further internal short cat5 to
the RB532?

Also, how many re-terminations do you have between the power
injector and the RB532?

 

Where do I find this info?

We have had a couple of cables that have shown link lights and passed

The cable did NOT pass the tester though.  :-)

It's actually the ethernet port acting up.  Thought maybe it was lack of
