We have 7 Catalyst 3750 Switches. 5 are 3750 PoE-48's and 2 are 3750G. We noticed that the ports on the 3750G looked pretty standard, but all the ports on 4 of the 5 PoE-48's have a pair of pins bent upward.
We've sat down and hypothesized their reason. We wondered if they were the pins used for PoE and there was some reason to connect them first, before the other pins.
We wonder about the 5th PoE 48, however. Its ports look identical to the 3750G's. If there is a reason to have the bent pins, are these the wrong ports installed in this PoE 48? And if this switch is fine and these pins do not need to be bent, why are they bent in the other 4?
