The power supplies, 2800w, is not "adequate" to support the X4748 line card. Read this: Cisco Universal Power Over Ethernet: Unleash the Power of your Network and then scroll down to the "Power Supplies Consideration for UPOE Deployment" section and it states:
For UPOE deployment with Cisco Catalyst 4500E, it is recommended to use one of the following two AC power supplies:
● PWR-C45-4200ACV
● PWR-C45-6000ACV

Thanks for reply,
But I also tested this on other WS-C4507R+E switch too, which is not in the network(In stock) but have same hardware(2800w) and configs as my working one. and on that switch both cards in slot 5 & 6 is providing POE to device simultaneously. ?
