HP NC370T PCI-X Multifunction Gigabit Server Adapter User Guide
C-5
Gigabit internal straight-through pinouts
Unlike connections in which the crossover function is implemented internally at the hub or
switch, the NC370T 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.
