21 Identifying the Server Ports
These sections describe the pinouts of the server connectors:
Gigabit Ethernet Port
The server has one auto-negotiating 100/1000BASE-T Gigabit Ethernet (GbE) system domain port that uses a standard RJ-45 connector. The transfer rates are shown in the following table.
Table 21-1 Ethernet Port Transfer Rates

1000BASE-T |
1,000 Mbps |
Network Management Port
The server has one auto-negotiating 100/1000BASE-T Ethernet management domain interface, labeled NET MGT. For information on configuring this port for managing the server with Oracle ILOM, refer to the Oracle Integrated Lights Out Manager (ILOM) 5.0 Documentation.
Serial Management Port
The serial management connector, labeled SER MGT, is an RJ-45 connector that can be accessed from the back panel. This port is the default connection to the server Oracle ILOM SP. Use only the SER MGT port for server management.
