which POE switch?
You can find Netgear FS728TP
Thu, 03/27/2008 - 6:55pm
You can find Netgear FS728TP switches new for right around $300, which I haven't used in production, and you can find Linksys SRW224p switches for right around $350-$400 that I have used in production with no issue other than I got a DOA switch, and Linksys RMA sucks balls. It took almost two months to get a replacement.

I have this switch, and other than being noisy, due to multiple cooling fans, I have been happy. It is not a fully managed switch, in that you can't get to a CLI. However, you can set up VLANs, and Trunks in the WebGUI.
The other thing I'd like to find is a single SMB device that has PoE, 802.11n, QoS, VPN (Hardware based), Remote management (maybe a MIB), Router, and a way to segment the wireless network into internal users, and public hotspot users. Then, as if that wasn't a tall order... put all of that functionality in an open source project... a guy can dream!

We tried one of those, it turns out that it only cut prowide around 175w to poe, and that all ports did reserve 15,4w so only 11 phone would work on this one, Zyxel know that.
We ended up with a EdgeCore ES3526VA-PoE

15,4w on all ports, management and rock solid. but not cheap :(

How much power do you need
Thu, 03/27/2008 - 10:42pm
How much power do you need to power phones over all 24 ports? I see the netgear FS728TP has a POE budget of 195 watts. The dlink DES-1228P can support 170w maximum for POE. The datasheet on the linksys SRW224P says it'll support 15.4w on 12 ports or 7.5w on all 24 ports (184w?).
Do you need 15.4w per phone?
For phones
Thu, 03/27/2008 - 11:10pm
you need 7.5w for a phone, Aastra 57i without sidemodule uses 4.2w.
You need 15.4w if you plan to power accesspoints, or webcams.
I just want to be shure that there is no problem with power so i always recomend my customers to use a POE swithch that can provide 15.4w on all ports.

We use the Dell 3448P and really like them. 48 10/100 POE Ports, 2GB ports, 2 SFP ports. We haven't had any issues and they are reasonably priced. We have two at our office and another 3 at various client locations. We have also used several of the Netgear POE products without issue. Stinksys on the other hand.... :)
i have a site with 3x dlink
Mon, 03/31/2008 - 9:38pm
i have a site with 3x dlink 1228p - all 24 ports lit with POE to snom phones on 2 switches - no problem, havent even had to create vlans yet.
have 2 other sites with the netgear 728 about 20 phones each, kind of like the interface better, and havent had an issue with that either.
now the linksys- one client with 4 (not my choice)- locks up severelly under heavey data traffic (5-6 stations downloading 1.5gb file), only a power cycle will allow data to pass throug the switch again - linksys support is worthless on the issue. another smaller site that occasionally has the same problem, so i know its not an isolated issue.
No you didn't miss anything.

No you didn't miss anything. Perhaps the poster missed your original criteria.
However I think you may want to look at the secondary channel.
The Cisco, HP, Extreme, Foundry and now Juniper are all Enterprise class switches and have feature sets and reliability that just can't compare to the sub $1000 list switches. However on the secondary market they can be had within your budget.
It's a mindset thing, if you are comfortable with gear from this type of channel.
Here are some examples found from sellers with significant feedback on eBay:
Place these numbers into the eBay search field

With regard to Cisco switches. The 3550 supports standard 802.af PoE, the 3524's which can be had for 3524-PWR switches support pre-standard inline power and work will all Cisco phones. Cisco 3524's may also work with Polycom's.
Hope this helps you sort it out.

I have no problem buying on ebay, and neither does my client. The cisco 3524's are dirt cheap. I think that only the older 301/501/601 Polycom phones work with it using the optional cisco POE adapter, but not the newer ones.
I guess I just need to put together a list of every good POE switch so that I can know what to look for on ebay. Phew... I've spent as much time picking out a switch as I did on the phones.

Does anybody know how much

Does anybody know how much power the Polycom 320 and 650's use? It looks like the client will be going with 18-20 phones, with the majority of them Polycom 320's. I've sort of settled on the Netgear FS728TP switch, which will output 195 watts over POE. So it looks like I'll have about 9 watts available per phone.

I'm in need of some smaller switches too. I've put together a spreadsheet of a few switches and their power output:

For small PoE switches it seems pretty good. Very inexpensive but doesn't feel cheap. Encased in metal so it dissipates heat well. Total of 8 ports with 4 being PoE. Been using for about 3 weeks now. I have it powering the following devices:
Aastra 57i
Aastra 480i
Cisco 7941
Polycom 320
I'll probably use it for my demo system.

I ended up getting the Netgear FS728TP. It's worked well with 15 Polycom 430's and 4 650's. Total power output is only 46 watts. The 430's use 2.1-2.5 watts each, and the 650's use 3.1-3.5 watts. I love being able to turn the power on and off to the phones, rebooting everything at once.
The only problem I've had is that when I set the ports to 10baset/full-duplex, the phones auto-negotiated at 10baset/half-duplex. That might be a problem with the phones or the wiring though. I got them to run at 10baset/full-duplex by setting the polycoms manually.
It also surprises me how slow the web interface is....
