RJ-45 to DB-9 Serial Port Adapter Pinout Information
The console port on a Juniper Networks device is an RS-232 serial interface that uses an RJ-45 connector to connect to a management device such as a laptop or a desktop PC. If your laptop or desktop PC does not have a DB-9 plug connector pin and you want to connect your laptop or desktop PC to the device, use a combination of the RJ-45 to DB-9 socket adapter along with a USB to DB-9 plug adapter.
Table 1 provides the pinout information for the RJ-45 to DB-9 serial port adapter.
