Hello,
So we implemented new switch stacks of ALE Omniswitch 6860E:
http://enterprise.alcatel-lucent.com/assets/documents/omniswitch-6860-datasheet-en.pdf
They are PoE switches with a default of 30 W per port, except for the first 4, which are up to 60 W.
We have 6 Polycom IP SoundStation 6000 phones that were originally plugged in to Cisco 3750 PoE switches.
We bought the 6000 phones years ago, and they've been working in production for >5 years i believe.
They were working fine on the Cisco switches, and then they stopped working on the ALE switches.
Upon boot up of the ALE switches, the Polycom 6000s displayed a set of 3 red solid lights on top.
The lanpower status on those switches shows a fault for the PoE status, not "searching," "powered on," or "powered off."
When I put them back on a Cisco switch, they then display 3 blinking red lights on top.
We have plenty of other Polycom phones (VVX410, SoundPoint IP550, Soundstation IP 7000, etc) in this environment that all worked just fine and powered on without issue.
We then tried to put them on the PoE injectors. Some combination of time of keeping them off / on, reseting the power on them (multiple times), and/or trying reset codes (ie 68*) seems to EVENTUALLY get them to work again (5 of 6 so far), though we are unable to pinpoint what. With the fault information from the switch, we speculate there is some issue with the power negotiation, but I am unaware of how that process works so far. We are also suspecting that some restriction or level of power regulation within the phone eventually gets eased and allows the phone to boot once again. Once we have gotten them working / online again, we have put 4 of the 6 back in place with PoE injectors, and turning the PoE off on the switch port.
I see many instances of related issues with the light codes on the Polycom forums, but nothing that seems to have definitive answers (unless i blatently missed something)....

Basically I am trying to understand the following:
1) What power negotiation issue might be going on? Does it have a failsafe to only start a certain way after a power issue?
2) What are the specific port requirements and/or compatibility (PoE settings / levels, speed, duplex, etc)?
3) Is there a sequence to reset this phone, if the display screen never appears (only 3 solid or blinking red lights on top)?
4) How can I revive the phone that still can't boot and displays 3 solid red LED lights?
Any help would be appreciated....
