Confusion Over 7985G PoE Requirement

I have a 7985G IP Phone which is not powering up after connecting it to a 3500 XL Inline power switch..This switch only supports Cisco Prestandard PoE. The datasheet specifically states that the phone can be powered using IEEE 802.3af from this link..

http://www.cisco.com/en/US/products/hw/phones/ps379/products_data_sheet0900aecd8030e546.html

However the FAQ Doc on PoE says that it can pe powered using Cisco Prestandard PoE from this link....

http://www.cisco.com/en/US/products/hw/phones/ps379/products_qanda_item09186a00808996f3.shtml#qa3.

So which document do I believe? Also can there any other reason why my Phone wont come up except for the the unsupported PoE on the switch?

7985 does not support Cisco Pre-Standard PoE. Looks like a documentation defect and I'd work on getting this fixed.

You would need IEEE Inline Power capable switch.

Hope this helps
