This appendix gives the pinouts for the server rear ports and identifies connectors on various server boards. Topics include:
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.

A.2 Network Management Port
The server has one 10BASE-T Ethernet management domain interface, labeled NET MGT. For information on configuring this port for managing the server with ILOM, refer to the Sun Integrated Lights Out Manager 2.0 User’s Guide.
|
Caution - If you are planning to use the network management (NET MGT) port, you must use a shielded Ethernet cable to maintain your server’s NEBS compliance. The cable’s shield must be grounded at both ends.

A.3.1 Serial Management Port
The serial management connector (labeled SER MGT) is an RJ-45 connector that can be accessed from the rear panel. This port is the default connection to the server. Use this port only for server management.
|
|
Caution - You must use a shielded twisted-pair (STP) Ethernet cable to maintain your server’s NEBS compliance. The cable’s shield must be grounded at both ends.
|
FIGURE A-3 shows the pin numbering of the serial management port. TABLE A-5 describes the pin signals.
