Console Port Connector Pinout Information; Usb Port Specifications For An Ex Series Switch - Juniper EX4500 Hardware Manual

Console Port Connector 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 console management device. The default baud rate for the console port is 9600 baud.
Table 28 on page 92 provides the pinout information for the RJ-45 console connector.
NOTE: 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 directly to a device, use a combination of the RJ-45 to DB-9
socket adapter and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.
