PTX1000 Management Cable Specifications and Pinouts
Cable Specifications for Console and Management Connections for the PTX1000
Table 1 lists the specifications for the cables that connect the PTX1000 to a management device.
The PTX1000 also has an SFP management port that supports transceivers that use fiber-optic cables. See Determining Transceiver Support for the PTX1000 for more information about supported transceivers.

Console Port Connector Pinouts for the PTX1000
The console port (labeled CON) is an RS-232
serial interface that uses an RJ-45 connector to connect to a console
management device. The default baud rate for the console port is 9600 baud.
Table 3 provides the pinout information for the RJ-45 console connector. An RJ-45 cable and an RJ-45 to DB-9 adapter are supplied with the PTX1000.
If your laptop or PC does not have a DB-9 male connector pin and you want to connect your laptop or PC directly to a PTX1000, use a combination of the RJ-45 cable and RJ-45 to DB-9 adapter supplied with the router and a USB to DB-9 male adapter. You must provide the USB to DB-9 male adapter.
