Hello,
Switched out a Cisco closet switch over the weekend and crossed our SS IP6000 Polycom's to the new Cisco 9410R switch. 6 out of 8 wound only boot to the deathly red blinking lights or blink once and no lights on both the old and new switches. Went and upgraded the FW to the latest 4.0.14 (SIP Polycom). Then with the IP6000 power supply kit (2200-42740-001) or crossing it back to the old Cisco switch it boots up just fine! Cannot get past the new 9410R PoE. Tried changing the port speed from Auto Negotiate to 100 FD, 10 FD...did not help. Cisco TAC case came back with only to get some mention of Avaya 1692 Conf. phones...."this model does not comply with IEEE standard and there is no issue with POE negotiation on Cisco side."
Thanks for any help.
