Console Port Connector Pinouts for the QFX Series
The console port (labeled CON or CONSOLE) 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.
You can also use a RJ45 to USB 2.0 Type-A cable and a RJ45 to USB 2.0 Type-C cable.
Table 21 on page 56 provides the pinout informaon for the RJ-45 console connector.
NOTE: If your laptop or PC does not have a DB-9 plug connector pin and you want to connect
your laptop or PC directly to a QFX Series device, use a combinaon of an RJ-45 to DB-9
adapter and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.
NOTE: We no longer include a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E
copper cable as part of the device package. If you require a console cable, you can order it
separately with the part number JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E
copper cable).
