I'm replacing a switch on our 4th floor with a new 2 switch stack. The uplink to this switch closet is a fiber run to the server room on the 3rd floor. All was installed by a predecessor. The fiber cables that come off the core switch stack and go to the fiber distribution box in the server room are marked as reverse polarity. The fiber cabling that goes from distribution box to the switch on the 4th floor does not have it's polarity reversed.
What's the purpose of doing this?
