Cisco 3750X POE issue on Cisco IP Phones.

  HI Team,

We have configured Cisco 3750X POE  series switchs with Stack.WS-C3750X-48P each with Redundant 1100W & 715 W PSU's. 
They are configured with Stack-Power in Sharing mode and the switches are Smart Stacked as well.

IP Phone and Access points are connected its working in last two years,

Now we are facing some issue on Cisco IP Phone and Access point,

When i have problem if unplug (disconnect & Reconnect) the IP Phone  from Switch port,
Power is not comming on switch port.

Plug it into another switchport of the same Switch it may not power in any port.


I tried shut & no shut and reconfigured on switch port ,
I have verified  multiple switch ports same issue on the switch
I have changed cable.

IOS Runing on Switches
