Hello All, I apologize for the slightly off-topic question, but I'm sure that the people best acquainted with the issue would be hanging around here. We recently deployed several Linksys POE switches for some smaller customers (10-24 station) and appear to be suffering from intermittent lock-ups of the SNOM phones attached. Obviously we are running Asterisk for the gateway, but I was curious if anybody has experienced similar issues. Phones will run fine, and then intermittently (and at different times for different ports) the phones will lockup and require a hard reboot. I've read on voip-info that the SNOM phones are apparently sensitive to lower-end network equipment, presumably with PoE only aggravating the problem. Question is, what are people using today to deploy PoE, and more importantly, PoE to SNOM phones? I believe the model we're working with is the SR224P from Linksys, and the entire model line of SNOM (3XX) Could anybody recommend some well-used/tested PoE equipment that you've found successful in your SNOM envionment? Looking for density of 24-ports plus, and ideally some lower end and higher end equipment, to satisfy the needs of the wide variety of customers we do business with?

I use on a regular basis the D-Link line, they work. With the SNOM you will want to set the ignore Ethernet unplug in case the Ethernet switch restarts (like a Netgear 7248 attached to a cheap fiber trans). Keep in mind that holding a GSM phone real close to some of the SNOM phones will cause them to lock up.

I am using the netgear switch 24 ports and 8 ports w/ snom 360 in a 10/100 network w/ no problem. the actual version of firmware of SNOM is 6.5.10 but the phone works w/ previews version. Look in your network. Bruno.

We then plug the Asterisk machine into one of the GigE's and the other GigE into the rest of the network. This works well with a centralised wiring closet - now all the phones are on their own switch - making interference more un-lightly. The Switch allows you to look at the power consumption - which technically means you can judge when there could be a "power problem". Oh - pretty well priced too.. we paid about US $680 for the switch - which makes it 'low end' cost wise. Currently has no SNMP :-( - but has a Linux friendly web front-end including setup of QoS, Access control and PoE power consumption. POE Ports Status Port Enable Power[mW] Current [mA] Port Enable Power[mW] Current [mA] 1 Enable 9 46 2 Disable 0 0 3 Disable 0 0 4 Disable 0 0 5 Disable 0 0 6 Disable 0 0 7 Disable 0 0 8 Disable 0 0 9 Disable 0 0 10 Disable 0 0 11 Disable 0 0 12 Disable 0 0 13 Enable 426 8 14 Disable 0 0 15 Enable 2333 46 16 Disable 0 0 17 Disable 0 0 18 Disable 0 0 19 Enable 2206 45 20 Enable 499 48 21 Disable 0 0 22 Disable 0 0 23 Disable 0 0 24 Disable 0 0 OK - so not many ports are active - but its interesting to see that each port seems to be consuming different levels of power... -- . . ___. .__ Posix Systems - Sth Africa /| /| / /__ mje at posix.co.za - Mark J Elkins, SCO ACE, Cisco CCIE / |/ |ARK \_/ /__ LKINS Tel: +27 12 807 0590 Cell: +27 82 601 0496
