Console Port Connector Pinout Information for an EX Series Switch
The console port on an EX Series switch 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 58 on page 123 provides the pinout information for the RJ-45 console connector.
An RJ-45 cable and an RJ-45 to DB-9 serial port adapter are supplied with the switch.
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 an EX Series switch, use a
combination of the RJ-45 to DB-9 female adapter supplied with the switch
and a USB to DB-9 male adapter. You must provide the USB to DB-9 male
adapter.
