Netra 240 Server Service Manual

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

• Gigabit Ethernet Ports
• Network Management Port
• Serial Ports
• Alarm Port
• USB Ports
• SCSI Port

---

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 Ports

The server has two serial ports, labeled SERIAL MGT and 10101. TABLE B-4 lists the default serial connection settings for both serial ports.

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.

Caution - You must use a shielded Ethernet cable to maintain your server's NEBS compliance. The cable's shield must be grounded at both ends.

FIGURE B-3 shows the pin numbering of the serial management port, and TABLE B-5 describes the pin signals.

FIGURE B-3 Serial Management Port Pin Numbering

If you need to connect to the SERIAL MGT port using a cable with either a DB-9 or a DB-25 connector, use a supplied adapter to perform the crossovers given for each connector. The supplied RJ-45 to DB-9 and RJ-45 to DB-25 adapters are wired as described in TABLE B-6 and TABLE B-7.

Serial Port (10101)

The port labeled 10101 accepts a DB-9 connector. Use this port for general purpose serial data transfers. FIGURE B-4 shows the pin numbering of the serial port, and TABLE B-8 describes the pin signals.

Alarm Port

The alarm port on the alarm rear transition card uses a standard DB-15 connector. In a telecommunications environment, use this port to connect to the central office alarming system. FIGURE B-5 shows the pin numbering of the alarm port, and TABLE B-9 describes the pin signals.

FIGURE B-5 Alarm Port Pin Numbering

USB Ports

The server has two USB ports for attaching supported USB 1.1 compliant devices. FIGURE B-6 shows the pin numbering of the USB ports, and TABLE B-10 describes the pin signals.

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.
