D-LINK PoE switch, does it work with cisco or do I need to do the cable trick?
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

Systems Admin; Telecom Newbie - What do I need?
Hi, folks. I am planning on implementing Asterisk in 2006, and need  
to budget for it now, so I need to know what I'll need to get. My  
company has about 50 users, and is currently languishing on a very  
old Comdial PBX. All of our client computers are Macs; our servers  
are mostly OS X, with a couple Debians and a Red Hat.
I am thoroughly experienced at systems administration, and can

Vlan question
There is a way to ensure traffic prioritisation...but it can work out a little expensive.
1.  Use 3Com 4400 PWR as your switch.
2.  Use 3Com NJ200/NJ220 (US) or NJ205/NJ225 (EU) POE Multiport switches
3.  Use 3CNJVOIP-CPOD POE --> 7960 POE/Data splitters for power and data connections to the phone.
The 4400 Delivers Power to the NJ2xx switches, these switches have 4 ports which can be

POE hub
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.

Cheap PoE switches/injectors?
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

LAN Switch w/ QoS
Does anyone have a recommendation for a 48 port LAN switch for a new * 
system?  I'm not happy with NetGear's reliability.

Cisco 79xx series IP phones
Shawn,
That's a complete load of manure.  I have an office full of 7960's, they
work great with asterisk with the SIP images loaded.  I'm about to pick
up a lot of 7912's (simple one line phones, same as the 7905 but it has
a built in switch).  These phones have also been confirmed to work with
Asterisk.
I would recommend not going directly to cisco, and just find a reseller

cisco poe
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%

Power Over Ethernet for *any* ethernet switch (or hub); product idea
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

3com Ethernet Power Supply
Hello,
I am trying to set up some Cisco 7940G phones with the
3com POE injectors.  I have the 3CNJPSE24 power injector,
this is the rackmountable 24 port injector.  My question is
does anyone know how to serial console into these things?
I have tried just about every cable setup I can think of and
baud rates but I can't seem to get anything out of it.  I want
to check to see what certain

Power over Ethernet (PoE) switch recommendations
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,

Polycom 501 power over ethernet
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

Polycom Power
I have a 501 with traditional power and a 301 with PoE. I rightfully assumed
that the traditional power from the 501 would work on the 301.
How do I get the PoE to work? Do I use the Polycom PoE cable in addition to
whatever PoE injection method I use? I have a Cisco PoE injector that works
on my Cisco AP350 and my 7960. No combination of this injector, the Polycom
cable, and the phone result in

OT: cisco 7960G powered by 3com 3CNJPSE
Is anyone using a 3com 3CNJPSE to power a 7960G?  
I have a couple of 7960Gs and 3CNJPSEs but no combination appears to
work.  Both phones work fine with a cisco power cube.  I get a 47.6V
reading across pins 5 and 8 on the patch cable coming from the 3CNJPSE.
The network still works through the 3CNJPSE, just no power to the phone
until I connect the power cube.  Using two straight through wired

Cisco power injector with GXP2000 phones
I've tried to use a Cisco power injector to supply power over Ethernet to a
GXP2000 phone without success. Although when I plugged these phone to a PoE
capable Cisco Switch it worked without a problem!
Knowing that all these three equipments implement IEEE 802.3af protocol, why
doesn't it work with the Cisco power injector? Anyone also had this problem
before?
Thanks,

IP Phone with Standard Power Ethernet
I am looking at phones for my asterisk system and seem to have a problem.
The only Power over Ethernet phones I can find that support the IEEE
standard are 3com. Cisco uses its own proprietary ( and is expensive to
boot ), snom has a different but equally non-IEEE method, and i'm havent
found another phone that I'm confident can do the job for our office.
