The ProCurve Networking Gigabit-SX and Gigabit-LX modules used in the ProCurve Switch 4000M, 8000M, 1600M, 2424M, and 2400M are set by factory-default to “1000 Fdx” whereas the factory-default setting for the ProCurve Networking Gigabit SX-LC and LX-LC mini-GBIC used in the ProCurve Switch 2650 and Switch 6108 is “Auto”. The configuration must be set to match on both ends to provide Gigabit connectivity.
