A.1
Gigabit Ethernet Ports
The 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 A-1
.
FIGURE A-1
shows the pin numbering of the
ports.
TABLE A-2
describes the pin signals.
