You are hitting the bug CSCsw18530 : Power Imax / Tstart errors may be reported with some third party PDs
This error indicates that PD is drawing over-current more than allowed/supported per IEEE 802.3af standard. Seen with some of the 3750,3750G,3750-E,3560-E, 3750-X, 3560-X, 3560-C, 2960S, 2960,2960C switches.
This issue is fixed in 12,2(55)SE3 , 12.2(58)SE1 and later releases. The following interface configuration commands have to be applied
to resolve the issue,
Switch(config)# int x/y
Switch(config-if)# power inline port 2x-mode
Switch(config-if)# no shut
The fix is present in the following platforms only : 3750-E,3560-E, 3750-X, 3560-X, 3560-C, 2960S, 2960,2960C.The other platforms
do not support 2X power mode and the workaround would be to use a longer cable.Possible workaround is using Longer cable (>50ft)
