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.
Table 29 on page 106 provides the pinout information for the RJ-45 console connector.
An RJ-45 cable and RJ-45 to DB-9 adapter are supplied with the QFX Series device.
NOTE: 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 QFX Series device, use a
combination of the RJ-45 cable and RJ-45 to DB-9 adapter supplied with the
device and a USB to DB-9 male adapter. You must provide the USB to DB-9
male adapter.
