4600/5600 phones and POE 2

[nzschooltech]

Good morning,

The 4600 and 5600 phones are POE powered. Avaya makes the 1151 series power supply to work with these phones but I assume any POE power injector or switch will be able to power them.

I am looking at a third party injector to supply a single phone as shown here:

http://www.cdlnz.com/productimages/pdfs/ippwr30.pdf

Its pinouts appear to be the same as every bit of documentation I can find on the POE standard. But on the 1151 it has marked on it that power is supplied on pins 7(-) and 8(+). Whereas the POE standard says that it is pins 4/5 for + and 7/8 for minus.

I'm confused as to how these phones can work on generic POE if the 1151 doesn't comply with the POE standard and I just want to be sure before buying injectors that the phones will work with them. No documentation I can find anywhere says that the POE on these phones is non-standard.

Thanks in advance if you can help me clear this up.

The phones will work with any PoE injectors, i have used several different brands without a problem.

You can use every PoE adapter as long it supports IEEE 802.3af, we use the 3com 3CNJPSE-GIG-ME this is a very cheap PoE adapter and they work great.

Thanks for the help.

With a bit more digging I found that there are apparently several different ways that POE power can be supplied to a device. The Power brick supplies one way and the phone will work out which way to get its power depending on what it is connected to (Apparently).

It depends on how many phones/network you have, a good PoE switch can handle up to 48 phones.

thnx for the *

THat's OK, I am having a good day and laughing at some of the jokes

nzschooltech,

That POE injector will work. 46xx/56xx Phones only use pins 1-3, 6 for data, and 7 & 8 for power. It dosent matter what is on pin 4 & 5. I've used several different POE injectors brands without problems. 16xx Series Phones are a different story, The need a 5V Power adapter, or a POE Splitter ( has 5V barrel plug ).

@AndrePa the power inserter is only for the 1603, not the 1608/1616 they work on a normal PoE injector

AndrePA if the injector supplies power on pin 4 and 8 the phone has to be able to use those pins, not much point using only 7 and 8 if they are both ground pins.

So I assume the phone is capable of adapting.

 

[AndrePa]

Bas1234, your correct only 1603 used POE Splitter, my bad. I have installed several 1603, only one 1608, so far.

nzschooltech, That Intelinet POE shows it's 802.3af, which should work. howevere looking at specs of that adapter, it dose show pin 7 & 8 negative, and pin 4 & 5 Positive. this would not work.
I've used avaya, cisco, even a Dell POW with no problems, on many 4610, 4620/1, 5620/1, never a problem. If your just installing one or two IP phones I would go with the avaya 1151. There no problems with them, probably same price, if not cheper than that Intelinet POE. If Your goint to be installing several IP Phones go with avaya or cisco POE blade.

The injector I have shown is POE Standard. That is what we have standards for. Avaya has stated all their phones comply with the standards and that they were the ones who instigated the standard.

So the phones must be compliant with the POE standard, and I have checked this out and I can assure you that supplying power between pins 7 and 8 is NOT what the standard says.

 

[sizbut]

... and the standard doesn't say that devices that use PoE can't also accept other methods of power supply.

So some engineer made it so Avaya phones could cope whether its was a POE supply or a legacy 1151 power brick, so what. Should we ring the standards police and call out the hit squad to stamp out that clearly deviant behaviour since it appears to offend.

Well that or you could just plug the phone in and move on. Promise we won't tell on you joining the deviant dark side of power mixers.

@sizbut

This forum is to help people, I would appreciate if you could keep sarcastic nonsense to yourself.

We have standards so that we can plug in one piece of gear without there being a problem of compatibility. Proprietary "standards" cause a lot of problems in this industry. For example Cisco used their own system of POE before the standard was introduced. This means Cisco have had to choose whether to keep their proprietary interface for their phones or support the IEEE standard, as it happens they chose to go for the standard but their gear also has to support their former proprietary setup for backward compatibility.

Now I don't particularly care if Avaya have a proprietary POE standard or not, what I do care is if they are going to label their gear as POE standard compliant then I can confidently expect that a POE standard injector or switch will work with it, because it's reasonable for me to assume if a piece of gear is marked as standards compliant that it will work with other standards compliant equipment, because you see, that's what a standard is about.

 

[nzschooltech]

AndrePA - thanks, but I can buy a POE injector now whereas our Avaya suppliers are real slow to get back with pricing.

 

[sizbut]

It wasn't nonsense and it not a propriatary standard. The phones are Poe compliant and they can also use Avaya's own power supplies. I just can't see why you find this such a difficult concept!
