Abstract: An increased connector port density assembly is disclosed for providing more connector ports than would normally fit on a faceplate. The increased connector port density assembly includes a stationary board and an extendable board connected to the stationary board on rails and with cabling. The extendable board has a first and second set of forward facing connector assemblies. The first set accessible when the extendable board is in either the retracted or extended position, whereas the second set of connector assemblies is accessible when the extendable board is in the extended position. The increased connector port density assembly is particularly useful for overcoming faceplate connector area availability limitations known in the art.
