This appendix contains the following sections that list pinouts for the connectors used with the CSS 11501, CSS 11503, and CSS 11506:

•RJ-45 Fast Ethernet Connector Pinouts

•RJ-45 RS-232 Console Port Pinouts

•RJ-45 Management Connector Pinouts

RJ-45 Fast Ethernet Connector Pinouts

Table B-1 lists the pinouts for the RJ-45 Fast Ethernet connectors on the CSS 11501 front panel and the 8- and 16-port Fast Ethernet Modules in the CSS 11503 or CSS 11506 chassis. The 10/100 Mb ports support autocrossover, allowing a connection to be made to any device using an Ethernet-type cable.

Connecting the Console Port to a PC

To connect the console port to a PC running terminal emulation software, use an RJ-45 to RJ-45 rollover cable and an RJ-45 to DB-9 female DTE adapter labeled Terminal. The DTE adapter is part of the accessory kit.

Table B-3 lists the signals of the console port and PC console device, and the pinouts of the rollover cable and the DTE adapter interfaces.
