Note This appendix only provides information on CDEs that were shipped after December 1, 2006 and contain the Lindenhurst chipset. For information on CDEs that were shipped before December 1, 2006 and contain the Serverworks chipset, see Appendix C, "CDEs with Serverworks Chipset."

Serial Console Interface Connector Pin Assignments

The serial console interface connector is a 9-pin, RS-232 D-type, DTE connector. A null modem cable is required to connect a workstation running the Linux or Windows operating system. Table B-1 lists the pin assignments for the serial console interface connector.

Ring indicator; input	9	In	RI

Serial Port Connector

The CDEs have one standard serial port connector located on the back of the device.

Figure B-1 shows the pin number assignments for the 9-pin, male D-shell serial port connector on the back of the device. These pin number assignments conform to the industry standard for RS-232 communications.

Ethernet Port Connector

The CDEs come with an integrated dual-port Ethernet controller. This controller provides an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet LAN.

To access the Ethernet port, connect a Category 3, 4, or 5 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the back of the device.

Note The 100BASE-TX/1000BASE-TX Ethernet standard requires that the cabling in the network be Category 5 or higher.

Figure 2-2 shows the pin number assignments for the Ethernet RJ-45 port.
