asterisk users - Apr 2006 - 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,

James

D-link has a nice one, optional 5 year warranty on some of the
commercial stuff....

Though beware, some of the D-Link ones only have half the ports with
PoE.

SMC 6824MPE.. Does 24 ports POE, with 2x 1GB uplinks, (RJ45 or  GBIC)
L3 Managed switch.

We've got four of them here, and I think they're great, the cost was
really reasonable.

Ingram no longer lists the MPE model, but it should be available still.

We have been using a 3COM 2226 PWR Plus and have had no issues

First some comments on other posts -

	Stay away from the D-Link switches.  The admin interface is horrible, 
and most only support PoE on half the ports.  Plus, most of their stuff 
comes configured with a static IP on varying RFC1918 networks - 
192.168.3.1, 192.168.10.1, etc, etc.  Not a good idea.  Plus, in the 
$400+ price range they really should have a serial port.

	I will never buy managed Netgear switches again.  I had two FSM7326Ps 
and the flash got corrupted several times, on both of them.  The web 
interface also had some serious reliability issues, sometimes causing 
the switch to reboot, which is of course totally unacceptable.

	I have been happy with Cisco (anything), HP 2650s and the Linksys 
SRW224P (or whatever it is) for managed PoE.  If you have the money (but 
not ridiculous, Cisco money) go with the HP.  Better warranty, better 
interface, better support than Linksys or D-Link.  Plus, I think they 
give you full 75W per port, as opposed to the SRW224p which can only do 
half wattage on all of the ports or full wattage on half the ports 
(something like that).  It's late in the day (and the week), so you'll 
have to cut me some slack!

	For the money, the Linksys can't be beat!

Beware.  Although the Polycom 501s will sink power over ethernet  
(that is they are powered by a cable pair within a cable that  
resembles ethernet), they are NOT IEEE 802.3af POE devices!!!!!  They  
work on 12 volts (I think -- haven't measured it) instead of 48VDC.   
So don't expect to buy a POE source and expect the phone to receive  
power just by plugging in a patch cable.  They must be powered by the  
Polycom voltage sources.

Nevertheless, here's what works for me:

Netgear FS108 :: Polycom injector cable :: RJ45 coupler :: patch  
cable :: Polycom 501

Some notes:
1.  The Polycom injector cable should be plugged into a POE port on  
the switch (the Netgear FS108 switch has both powered and unpowered  
ports), or the Polycom injector will not source power.
2.  The Netgear FS108 is NOT sourcing power.
3.  The patch cable is a 50-foot CAT5.
3.  To beat a dead horse, the Polycom 501 itself, is NOT a POE phone,  
IMHO.  Caveat emptor.

It is if you buy the PoE injector cable instead of the self-powered one.

Actually, as far as I know, only one of the D-Link POE switches is like 
that, the DES-1316 has 16 ethernet ports, with 8 of them POE. The 1516 
has 26 POE ports (with two of them gig).

James, 24 ports PoE on a Linksys switch occupied with Polycom IP
501's, no problem. The Polycom's use approx. 4W, so the 7.5W per port
(if you use more then 12) is no problem at all.  Agreed, a more
expensive switch (Cisco,HP,Alcatel) might be better, but the Linksys
is worth the money!
