RJ-45 to DB-9 Serial Port Adapter Pinout Informaon
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 combinaon of the RJ-45 to DB-9 socket adapter along with a USB to DB-9 plug
adapter.
Table 79 on page 141 provides the pinout informaon for the RJ-45 to DB-9 serial port adapter.
