Forced POE+ on a cisco 3560x

jeremykemp1 · ‎06-14-2013

We are configuring several 3560X-24P switches for a customers new system. We also have several cameras that need ~25W of power to run(802.3at spec) These cameras will run with a PowerDsine injector but not with the cisco switch. In troubleshooting it appears the cisco 3560x wants LLDP or CDP to enable power beyond 15W. The camera uses the 2 event hardware classification but doesnt use LLDP or CDP.

I also read on the new upoe cisco models that you can run a forced mode:

"If the end device is PoE-capable on both signal and spare pairs but does not support the CDP or LLDP extensions required for UPoE, a 4-pair forced mode configuration automatically enables power on both signal and spare pairs from the switch port."

Am I missing something or is there just no way to enable POE+ without CDP or LLDP with this switch?

So far we have turned the inline power to 30W and the police mode is currently off.

Thanks in advance.

I too am facing the same problem. Does Cisco support a Class 4 Layer 1 only PD ? Cannot see anyone from Cisco answering this question.
