Gigabit over Copper Internal Straight-Through Pinouts
Unlike connections in which the crossover function is implemented internally at the hub or
switch, the NC320T PCI Express Gigabit Server Adapter provides its own automatic
crossover function. This means you can wire twisted-pair media straight-through for adapter-
to-hub, adapter-to-switch, or adapter-to-adapter connections using the pinouts shown in Table
C-4.
NOTE: To operate at Gigabit speeds, all four pairs of wires must be terminated within the RJ-45
connector.
