That's unusual, but they do
make a "universal power adaptor" if your network is not PoE .

Henry,
That's what I thought you meant, this phone doesn't come with a
transformer at all! And there is no where to plug one in (I would of
been mildly annoyed if I had to go out to RadioScrap and get one but if
it listed the V/A I could of). No where to plug it in on this model
though, perhaps I selected a bad model...I only went with this one
based on another TAUG member (who is a technician at a
telecommunications distributor)'s recommendation.
I am sure that this requires at a minimum the DWL-P50 by D-Link (if not
the DWL-P200 although Nabeel says it doesn't require that...).
Thanks,
Chad

All the IP phones need power to light the display and run the
electronics etc. the phones come with a power adaptor (transformer)
that plugs into the back of the phone. These power adaptors have to be
plugged into a power bar at the desk along with
everthing else that a modern office has (it gets ugly). So putting the
power bar back in to the closet or telephone equipment room makes a lot
of sense.
A technician can easily screw some cheapo power bars on the wall, plug
in the adaptors and feed each network cable individually.
You can just select which phones you'll need in and emergengy and
put them on a UPS the rest will die when there's a power cut but
at least you can stay in business with spending a fortune on a massive
PSU or generator.

Thanks for the reply Henry.
I just ordered in the Aastra 480i's as they were recommended as a good
model...however I'm not sure what you mean about the transformer that
comes with the phone...Perhaps you could elaborate? Or perhaps this
particular phone doesn't come with one?
Thanks,
Chad

I agree for a few phones there is no
point in buying PoE routers.
If you have kept the tranformers that came with the phones then just
get the injectors plug in the transformers and power up
the phones from the "head end".
There is a big advantage in doing this way .
You can select which phones should be kept "alive" in a power fail mode
and limit the reserve battery requirements.
Each phone uses about 1.2 amps so if you have 10 phones drawing from a
single power supply the cable needs to carry 12 amps
which is the fusable rate of the cable itself, so if one phone develops
a short the it will draw 12 amps and melt the phone and the cable.
Anyway if you need to know more we could take it over to the other list

The D-Link P200s are overkill for your needs. They are PoE Adapters
(injector and splitter). All you need is an injector if you are using
PoE-capable phones.
Let me know if you need specific model numbers.

I guess I should mention that I'm a reseller...so I wont be ordering
from tigerdirect or anything, it's just that I haven't used any of
these low end POE switches before and I don't like trying things out on
clients without at least getting a recommendation ;)
The same problem exits with that netgear as with the linksys (not just
the price), a 24 port switch for an office with 3 phones is
overkill...I think an 8 port would give them enough room to add a few
more desks. As for needing gigabit, I suppose not they do move some
large files around but it's just that gigabit is very cheap in the
small switches so it's 'why not'. Of course why not because they don't
have POE is a good answer...but 3x55$ for the D-Link P200's and 1x79$
for a 8 port gigabit linksys switch is cheaper than these giant 24 port
switches (which are just gigabit uplink...which would probably be ok to
use for the server and then 100Mb to the clients).
Bleh, I guess in about a year they'll have what I want for the price I
want...in the mean time I'm going to have to settle.

In such a small install not sure
how much Gigabit your
going to need,
but if it is a concern take a look
at the NetGear 24 port that TigerDirect has at CA$381. Is 24
10/100port, 12 w POE and 2 Gigabit coper plus 2 GBIC slots.

Also right now they have a special
to get either a IPod Nano or a NetGear Storage Central( until Jun30 )

That looks not bad but once I get
up near that price range
I can get
a Linksys SRW224P and propose the
cost difference because of the gigabit + QOS etc etc; But I don't want
to oversell. I'm still wondering if maybe the three POE injectors from
D-Link + a
Linksys 5
port or 8 port gigabit workgroup
switch wouldn't be a more sound decision.

It's a bit more but a quality box.

Take a look at Netgear, they may have something, Mark.

Evening,
Just wondering if there is a more economical way to do
POE in a SOHO
environment (3 phones) other
than using the D-Link
DWL-P200 modules
on each phone. I was looking
for low end POE enabled
switches from
Linksys and D-Link and didn't
see any...before I go ahead
and order
the DWL-P200's does anyone know
of a small 8 port POE
switch in the
$175-250 range that I
overlooked, preferably with gigabit
(wow I'm
asking a lot for a little ;) ).
Thanks,
Chad
