RJ-45 Connector Pinouts for the PTX3000 Auxiliary and Console Ports
The auxiliary and console ports on the Control Board and Routing and Control Board (RCB)(labeled AUX and CON) are RJ-45 receptacles that accept RS-232 (EIA-232) cable. The AUX port connects the Routing Engine or RCB to a laptop, modem, or other auxiliary unit, and the CON port connects the Routing Engine or RCBto a management console. The ports are configured as data terminal equipment (DTE). Table 2 describes the RJ-45 connector pinouts.
