Connector Pin Assignments
This appendix lists the connector pin assignments for the Cisco Content Delivery Engines.
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.

Serial Port Connector
The CDEs have one standard serial port connector located on the back of the device.
Note
The CDE280 Engine uses a KVM console or CIMC virtual console. For more information on the KVM console, see the “KVM Console” section
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.

KVM Console
The KVM cable provides a connection into the server, providing a DB9 serial connector, a VGA connector for a monitor, and dual USB 2.0 ports for a keyboard and mouse. With this cable, you can create a direct connection to the operating system and the BIOS running on the server.

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; it 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 B-3 shows the pin number assignments for the Ethernet RJ-45 port.
Figure B-3 RJ-45 Ethernet Port Connector
Fiber Connector Type
The fiber connector type used to connect to the SE dual-fiber NIC cards is the GLC-SX-MM.
Note
If you are using a TenGigabit network interface, you must use the Intel Transceiver Twinax cable.
Cable Pin Assignments
Figure B-4 through Figure B-6 show the pin assignments for the cable connection for an RS-232 null modem, RJ-45 straight-through cable, and RJ-45 crossover cable, respectively.
