Originally had 4503 and Cisco 7936 IP phone functioned properly.
Replaced 4500 with a FCX648S-HPOE-ADV. 7936 IP phones will not function. All other Cisco, Avaya, and Fujitsu IP phones functioned properly. cdp enabled; lldp enabled on FCX648S-HPOE-ADV.
Replaced FCX648S-HPOE-ADV with a 4503-E. All IP phones, including 7936 functioned properly.
Any thoughts or insight?

The 7936 has 10/100 MB port - suggest you try and set the speed duplex to 100 full (done on the interface level via" speed-deplex 100-full" command.
