I have a situation to setup a network of workstations to communicate in Gb speed using the existing 62.5/125 MM fibre infrastructure between 3 buildings separated by a distance of 300m. I am thinking of using the Gb uplink ports in the Catalyst 2960 switches to set up the Gb network. Each building has a 2960 series switch and they are networked via the fibre GLC-LH-SM transceiver module installed in the uplink ports . Question is can the remaining free Gb ports not associated with the used fibre ports be for the workstations? The attachment shows the proposted connectivity, Thanks.
