Recently there is a lightning strike in the office area and caused some of the LAN points to loose PoE function.

Those affected interfaces on core catalyst 4500 series had error like this:
%C4K_SWITCHMANAGER-4-S2WERRORREPORT: (Suppressed 9 times)PimEthAutoNeg: S2w Read/Write Error for port Fa6/6

Resolution: Do a hardware module reset.
Cisco# hw-module module 6 reset

The command will switch OFF & ON whichever module slot specified.
