** Updated - Oops - Typo - it's a 3550, not a 3350 - Sorry! **
Have a strange problem - we are doing a deployment with Polycom 430's and Cisco 3550 24-Port PoE Switches, and with the 430's, they reboot as soon as they get to "Loading sip.ld" but if you plug the power supply into the phone it works fine. Also, a Polycom 600 plugged into the switch works fine.
Has anyone ever seen this before?
We have quite a few of these Cisco switches and would like to keep them if possible.

Greg,
I saw something similar with an Adtran 7100 POE & Polycom IP-430 phones earlier this year.
I think (Feb 2007) it turned out to be something with the way the Firmware was/was not hitting the 430. Once the phones were updated / current they worked fine. Although the 7100 was eventually returned due to other issues.
Good luck..
"Loading sip.ld" it reboots.
Have I mentioned how much I hate Cisco?
I am going to try a 501 tomorrow on these switches - if that works, they are just going to do the rest of the phones as 501's. We have used Polycom's with Netgear, D-Link and Linksys PoE Swtiches and they have all worked perfectly.
I will post with a test - I probably will take a 330 over there too just to have a cross-platform report.

Hey,
I just went through the Smartnet ^%$$^% process to get SIP code for my 7970s and then had to load three SCCP version to get the loader to the point that the Phones would take the SIP load.
What should have been a five hour install / configure took the better part of 24 billable hours, plus multiple wait times for things like Pwr Cubes that are unique to latter models as my 7940/7960 cubes don't fit without a good knife. .

Hey Greg,
Having a similar issue here with a Polycom 320 and a Linksys SRW208p PoE switch.
The Polycom sometimes will boot up and stay at idle screen for a few seconds and then all of a sudden the two Line keys will start flashing yellow, and the phone reboots. When it gets back to loading sip.ld it'll flash and reboot again.
I haven't tried the power adapter but I'm sure it'll work then.
The weird thing is the same phone was working fine for over a week on the same server and on the same switch model.
I moved the server and the phone to a new location, but it's the same model switch. No luck so far. Can you tell me what you found to be your problem in the end?
We have seen weird problems like this with certain switches that use spanning tree. Try bypassing the Cisco switch with a basic dumb switch in order to get the firmware loaded and see if that works.
Also, realized that I typed the wrong model number - it's a 3550, not a 3350! Dang fat fingers!
The problem with this particular switch is that it's not 802.3af PoE Compliant - and the Polycom 430's and 3(2,3)0's need that to function correctly - We tested a 501 and 600 and they both worked fine.
Funny thing though:
Pricegrabber.com - Cisco 3550 24-Port PoE (Cisco, not 802.3af) - $2,750
Pricegrabber.com - Linksys SRW-224P 24-Port PoE Switch (802.3af Compliant!) - $371.00
Ahhh, the cult of Cisco - 7.4 times better? I think not...
Greg
P.S. Tried letting the 430's provision successfully and then putting them back on the Cisco switch - still doesn't work. stechnique, I don't know why you are having problems with the Linksys switch - it's what we use ALL the time and it works perfectly - what firmware-polycom are you using, and have you run setup-polycom to configure the load?
Greg,
Did you configure the switches? Please post a "show run" and I will take a look at the config.
The switches may be set for auto discovery and sending out a CDP advertisement to auto configure the phones.
The Cisco switches do a few things the Linksys, I would assume they bought them for a reason not just the brand name. If not then they did spend too much money.
Scott
Update: Are you using VLAN tagging? I just checked on the 430's you can disable CDP. It would be a shame not to set the phones up to auto discover the voice VLAN and set the 802.1p QoS tagging. If the switches are trunked together this could be very important.

I spent around 20 minutes playing with a Cisco 3550 PWR and a Polycom SoundPoint IP 330
I tried these options but no success, the polycom still reboots during loading sip.ld
I tried these configurations on the 3550's port which was connected to the polycom
1) disabling spanning tree on the port (spanning-tree bpdufilter)
2) disabling the CDP (no cdp enable)
3) disabling the dhcp server on 3550 (no service dhcp)
4) enabling the portfast
5) manually configuring a dot1q trunk on the port.
and the phone is still rebooting.
any idea?
The Polycom writes a boot log to the tfto server.
There may be some useful data in that log.

"It seems that right when the phone finished loading the sip.ld application, it would drop the Ethernet link for a second which would disconnect the power long enough to force a reboot. To resolve the issue we configured the ports to keep the power on for the initial 5 minutes of the port going up"
COMMANDS:
int range fa0/2 - 24
power inline delay shutdown 20 initial 300
I give this guy all the credit .
