Ethernet Port
The Ethernet port, which is located on the L2 controller, uses an RJ-45 connector (see
Figure A-4).
Figure A-4

Table A-8 shows the cable pinout assignments for the Ethernet port operating in
10/100-Base-T mode and also operating in 1000Base-T mode.
Note:
The system auto-selects the Ethernet port speed and type (duplex vs. half-duplex)
when the server is booted, based on what it is connected to.
