HP NC7131 PCI Gigabit Server Adapter - Manual (Page 23)

Specifications C-5
Gigabit Over Copper Internal Straight-Through Pinouts
Unlike some connections in which the crossover function is implemented internally at the
hub/switch, the NC7131 adapter provides its own automatic crossover function. This means you
can wire twisted-pair media straight-through for adapter-to-hub/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.
