Connector Pinouts

This appendix gives the pinouts for the following Netra 240 server rear ports:


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.

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 ALOM, refer to the Sun Advanced Lights Out Manager User Guide for the Netra 240 Server (817-3174).

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.

Serial Management Port

The serial management connector (labeled SERIAL MGT) is an RJ-45 connector that can be accessed from the back panel. This port is the default connection to the system, and you should use this port only for server management.

SCSI Port

The SCSI port is a multimode Ultra 160SCSI interface. To operate at Ultra 160SCSI speeds, the part must be in Low Voltage Differential (LVD) mode. If a single-ended device is connected to the server, it automatically switches to single-ended mode. FIGURE B-7 shows the pin numbering of the SCSI port, and TABLE B-11 describes the pin signals.
