RJ-45 Fast Ethernet Connector Pinouts

Table B-1 lists the pinouts for the RJ-45 Fast Ethernet connectors on the:

•CSS 11050 and CSS 11150

•Fast Ethernet Module

Table B-1 RJ-45 Fast Ethernet Connector Pinouts

Signal Name	RJ-45 Fast Ethernet Pin Numbers	Crossover Cable Pinouts

When using the Fast Ethernet connectors to connect the CSS to a:

•Server or a workstation, use a straight-through cable

•Switch or a repeater, use a crossover cable

RJ-45 RS-232 Serial Connector Pinouts

RJ-45 RS-232 Serial connectors are the interfaces for the:

•Console and Diag ports on all CSS 11050 and CSS 11150, and CSS 11800 Switch Control Module (SCM) and Switch Fabric Module (SFM).

•Diag1 and Diag2 ports on the SFM2. These ports provide both console and diagnostic functionality on each of its RJ-45 RS-232 Serial connectors.

Table B-2 lists the RJ-45 RS-232 Serial connector pinouts for the Console port.

RJ-45 to RJ-45 CSS Cisco Console Adapter Cable

Table B-6 lists the pinouts for the RJ-45 to RJ-45 Cisco console adapter cable that plugs into the CSS console and converts its pinouts to a standard Cisco console port. Once you plug the adapter cable into the CSS console port, you can connect a standard Cisco console cable to the adapter cable.

---

Note When you use the adapter cable to connect to a terminal server, you must plug the adapter RJ-45 male connector directly into the CSS console port. Then, connect the adapter RJ-45 female connector to the terminal server interface cable. Do not directly connect the adapter cable to the terminal server port.

Custom Cable Pinouts for Attaching the CSS Console Port to a Communication Server

This section decribes how to create a cable to connect the CSS RJ-45 RS-232 Console port to a Cisco Systems router functioning as a communication server.

The CSS 11050, CSS 11150, and CSS 11800 support connection from their RJ-45 RS-232 Console port to a Cisco Systems router functioning as a communication server. To make the connection between a CSS and a Cisco communication server, you must make your own adapter cable or full cable as described in this section.

Depending on the Cisco Systems communication server in use, your cabling requirements may vary. Cisco communication servers handle multiple device interfaces, and the communication server platforms provide a number of methods to connect serial devices, including RJ-45, DB-9, and DB-25 connectors. To connect a Cisco communication server to the CSS Console port, review the communication server connections listed below and use the recommended cables:

•A multi-pin D-type connector attached to an octal serial cable (also known as an "octopus" cable or breakout cable) provides a rollover DTE connection. For this connection, make an adapter cable using the connector pinouts defined in Table B-7. In addition to this adapter cable, you will also need a female-to-female RJ-45 adapter to connect the communication server to the the CSS (the RJ-45 adapter is included in the CSS Console cable kit).

•A RJ-45 pin female connector (without a rollover DTE connection). For this connection, you can either:

–Make an adapter cable using the connector pinouts defined in Table B-7. In addition to the adapter cable, you will also need a female-to-female RJ-45 adapter and a RJ-45-to-RJ-45 rollover cable to connect the communication server to the the CSS (both the cable and adapter are included in the CSS Console cable kit). Note that the DTE side of the rollover cable is attached to the CSS Console port.

–Make a full cable that includes the rollover functionality directly in the cable (using the connector pinouts defined in Table B-8).

•A DB-9 or DB-25 pin female DTE terminal adapter connector. For this connection, make a full cable that includes the rollover functionality directly in the cable (using the connector pinouts defined in Table B-8). In addition to the full cable, you will also need a RJ-45-to-DB-9 or RJ-45-to-DB-25 console cable to connect the communication server to the the CSS (both cables are included in the CSS Console cable kit).
