Hey, all. We're rolling out VoIP, and I'm wondering about PoE recommendations, as we're going to have to replace our current network equipment. My first inclination would be to just plunk down the cash and do a Cisco system, but I'm relatively certain that would get shot down by finance. Any recommendations for a couple-hundred-port solution with VLANs, PoE, and QoS? Don't care much if it's in a single chassis or not, so long as it has Gbit uplinks. Thanks! -Ken
Linksys SRW248P or something like that... something from linksys anyway are quite capable of all you mentioned... maximum 24 port powered though iirc.

We've used Linksys SRW224P units at quite a few places without issue. For a little lower cost, we've also used Netgear FS726 series switches. Personally, I prefer the Linksys ones - they have a serial port for administration rather than relying on you doing it over the LAN (though they have a pretty web interface, too). The pretty web interface is less fussy than the Netgear one (which seems unreliable in non-Internet Exploder browsers). On the other hand, the Netgear is substantially less deep (an issue in some wallmount cabinets) and definitely a lot quieter. Regards, Chris

(gross rounding, using 100Kb/sec per phone, rather than ~80 - make the sums easier and builds in a margin) 10 calls per Mb/sec. So for a 24-port switch, 24 phones all talking to 24 extensions off that switch, the max the uplink port is going to be pushing out is 2.4Mb/sec. For 200 extensions, say 9 x 24 port switches, with a single top-level (non PoE switch) switch with the PBX plugged in along side the 9 downlinks, that single PBX link will be carrying 2.4*9 = 22Mb/sec if all phones are in-use at the same time (and the PBX is carrying media) Now you may not want to build the network like that, but it seems that Gb is overkill just for the VoIP side of things. (And with that many extensions, I would suggest keeping all the phones on one set of switches) (Then again, it might not be possible to get big PoE switches without Gb uplinks, so it might be a moot point!) So satisfy my curiosity - why Gb uplinks? Cheers, Gordon
We've been EXTREMELY happy with the HP 5400ZL series chassis switch. Price per port is about 1/3 that of Cisco when it comes to POE. Price is about $100 per port and all ports are 1Gb with POE by default -- you can't get modules that don't have 1Gb and POE. 10Gb uplinks are available with other modules.

We have 4 of them and they have worked very, very well. I have 25 polycom phones at present doing PoE from them and everything is working great. They are reasonably priced, come with a lifetime warranty and free software updates. (Unlike with Cisco!) Norman Franke Answering Service for Directors, Inc. www.myasd.com

I also can't recommend Zyxel's support enough, I had initial concerns about the PoE budget and within a couple of rings, I was through to someone who actually knew the product inside out.

Hi Ken, we are quite satisfied with Linksys SRW248G4P. 48 port PoE, 4 GB uplinks and 2 GBIC slots. VLAN, QoS and all the like is on board. Around US$600 I guess. Only drawback in my opinion is that they are loud like a starting airplane. You definately don't want them next to your desk. ;-) Christian Ken D'Ambrosio schrieb:> Hey, all.

None have caused problems to date. In the server room, we have Dell PowerConnect 3548P switches which are fully managed driving a mix of phones, access points cameras. They are excellent value, Cisco are way overpriced. regards, Drew -- Drew Gibson Systems Administrator OANDA Corporation www.oanda.com
