[cisco-voip] CSCtf09186 9971 no video as switch can't power camera

[Jason Aarons (AM)]

I can't view this in the BugToolkit.  Is there a switch-side workaround?  Seems CME phones aren't taking/letting me set this in the phone's .cnf.xml file.  I see the switching show power inline 12.0 watts and not 14.4 I would expect for a 9971.

I have a WS-C3750-24PS-S is there a fixed IOS software version for my switch?

9971 Release Notes
Cisco Unified IP Phone 9951 and 9971 Power Negotiation when using a Video Camera
There is an issue (CSCtf09186) with some 802.3af switches, which results in the Cisco Unified IP Phone 9951 and 9971 unable to negotiate for the additional power required to operate the IP phone's camera. To power the camera, use the Cisco Unified IP Phone 9951 and 9971 phone's Power Negotiation (Enabled/Disabled) parameter to disable the IP phone's power negotiation. To disable Power Negotiation parameter access the Product Specific Configuration of Cisco Unified Communications Manager 8.5 and later releases. A device pack must be installed to add the configuration parameter to the database for Cisco Unified Communications Manager releases before 8.5. Disabling power negotiation enables the IP phone to power up the camera and to use up to 15.4 watts (the AF maximum) without the need to negotiate with the switch. Use this workaround until the switch software is updated with a fix.
