similar to: Polycom power over ethernet (PoE) cables for 500/501, 600/601 and 650 sets

PoE, or 802.3af, uses a device detection routine to determine if the connected device needs power. The process, in greatly simplified terms, is as follows: 1. Detect link state 2. Send a pulse of a known frequency and intensity over the TX/RX pairs 3. Listen for reflection. 3a. No reflection- provide power 3b. Reflection- no power Devices that comply with 802.3af have filters designed

Hi, Do you need a special cable and power for that unit or you can run it of PoE Switch? Thanks. robert

Hello; We have a cisco switches but they are not PoE and we need only to have PoE device so the cables come for it first to provide the power and then goes to the switch (to be like batch panel), is there something like this that can be used for the IP Phones?

Based on several threads I've read on this list, I assume that it would be handy to supply POE (power over ethernet) in an environment without having to purchase POE switches (assumed expensive) and abandon one's existing (familiar/custom/not-yet-expensed/etc.) switches/hubs. Assume I have a non-POE switch with 24 RJ-45 (ethernet) ports. I design a 1U box that can be mounted just

As an alternative to the "expensive" PoE switches out there, I found the D-Link Web Smart DES-1316 switch for just around $400. Now, the issue is, it does 802.3af power and, as I've found out through previous discussions, this original 76?0 series phones (the non G variety) do not use 802.3af. So I'm assuming I just need to use the special cable thing as per

3com have some goods POE kit and some very nice managed wall jacks that supply POE and are fully managed. Here's an auction that the seller just closed:- http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=40990&item=5708757277&rd=1&ssPageName=WDVW Last time I spoke to him he had 5 boxes of 20 units and was willing to sell them at around $575 with a bit of arm twisting.

When I bought two Polycom 501 SIP phones, I naively thought they were Power-over-Ethernet (IEEE 802.3af) because they were "powered over ethernet." Silly me. Polycom must have some odd voltage or funny way of injecting the power, because the POE switch I bought for them (Netgear F@510P) won't power them, though if I use the Polycom-supplied AC adapter and ethernet power

I know this is on the wiki, I just want to confirm so I don't blow up my cisco phones. I've got several cisco 7940's all running using cisco power cubes. However, my boss wants me to switch just a few over to poe, but doesn't want to fork out the dough for a nice cisco poe switch, or anybody else's poe switch for that matter. So my question is, what is the '99.999%

Sorry for posting slightly off topic, I use an Avaya 1152a1x midspan device to deliver power some Snom phones. The Power distrubution unit seems to be identical to PowerDsine PD-6024G/AC/M. I can get some basic information via SNTP (networking setup, uptime) but no port monitoring and no monitoring of power output using snmpwalk on the device. Does anyone has experience wit such an device?

I need to connect up to sixteen phones per building, I can use a cheap hub, but POE would be useful. Is there a cheap POE hub available? Everything I have seen has been expensive. Chris Mason

I -think- that the Sipura 841 was PoE... and I'd been anxious to find out. However, according to Atacomm.com, it's been delayed until mid-January. *sigh* So: does anyone know of a (decent) phone that meets the following criteria, and isn't too expensive? - SIP - two (or more) lines - some form of TCP/IP-based configuration - 802.3af (power-over-ethernet) - 100 Mbit passthrough (not

Hi, I'm not clear on how to use Power--over-Ethernet, specifically with Polycom phones. What I understand, is that by buying the Polycom 501 with the 802.3af cable bundle, I simply connect my phone, through the Polycom provided "special" RJ-45 cable, into a PoE capable switch, and voil?! Is this true? And if so, what happens when the Phone doesn't connect directly to the

Hi: I have a Sangoma A200 card installed in a server with two FXO modules and one FXS module. Analog sets connected to the FXS module have a "squeaky static" -- it's like static mixed with the sound of someone vigorously cleaning a window a few doors down. In other words, it's not a classic static noise, but it is noise, and it's distracting. Remote callers can hear this

Hey guys, I was wondering what POE solutions are being used ? Ive done some searching on google and found that PowerDsine seems to be good brand. Any comments,suggestions, and experiences on POE hubs other POE products would be greatly appreciated. Thank you, Steve Maroney

I am hoping that someone has had better luck with this than I have. I would like to connect Cisco 7940s and 7960s to the Netgear FS116P, and take advantage of its POE. I know that the Cisco phones use Cisco's "pre-standard" POE implementation, but as I understand it the difference is really only two pins. I bought a bunch of PowerDsine inline power adapters which supposedly change

I'm trying to spec out hardware for a new office, and I'd like to include power over Ethernet as an option. I've seen a handful of PoE injectors around $1000 for 24 ports and a couple switches up around $2500 for 24 ports. Are there any cheaper options, short of buying a boatload of 1-port injectors off of ebay? I don't really need more then 24 ports of PoE out of 48 total

Has anyone gotten the Lucent / Orinoco injectors (AE-1, AE-6, AE-12) to work with the Cisco 79* series phones? I'm not sure if the are the statndard POE or not.... -Darren

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Are any versions of the Cisco 7940/7960 or 7940G/7960G phones compatible with the 802.4af Power over Ethernet Standard? Ok, I know the question has been asked before, but googling has turned up several contradictory results: 1/ No - not at all 2/ Maybe - 79XXG will work 3/ With a special cable/dongle (a la wikki) I am looking at getting

Hi listers, I am looking for people who have used Power over Ethernet switches, primarily in conjunction with Polycom IP 501's. I've been looking at the Linksys SRW224P, since I've had good luck with the SRW224 in our office. However, Nortel, Cisco, Adtran, etc. all have an offering, all of which vary in price. I would appreciate any input people have to offer. Thanks, James
