Gigabit Ethernet Ports
The Netra 240 server has four autonegotiating 10/100/1000BASE-T Gigabit Ethernet
system domain ports. All four Ethernet ports use a standard RJ-45 connector, the
transfer rates for which are given in
TABLE B-1. FIGURE B-1 shows the pin numbering
of the ports, and TABLE B-2 describes the pin signals.
