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 3 provides the pinout information for the RJ-45 console connector.

Note

If your laptop or PC does not have a DB-9 plug connector pin and you want to connect your laptop or 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.

USB Port Specifications for the QFX Series

The following Juniper Networks USB flash drives have been tested and are officially supported for the USB port in the QFX Series:

  • RE-USB-1G-S—1-gigabyte (GB) USB flash drive (except QFX3100 Director device)

  • RE-USB-2G-S—2-GB USB flash drive (except QFX3100 Director device)

  • RE-USB-4G-S—4-GB USB flash drive

Caution

Any USB memory product not listed as supported for the QFX Series has not been tested by Juniper Networks. The use of any unsupported USB memory product could expose your device to unpredictable behavior. Juniper Networks Technical Assistance Center (JTAC) can provide only limited support for issues related to unsupported hardware. We strongly recommend that you use only supported USB flash drives.

Caution

Remove the USB flash drive before upgrading Junos OS or rebooting a QFX Series device. Failure to do so could expose your device to unpredictable behavior.

Note

Executing the request system snapshot CLI command on a QFX3500 device requires an external USB flash drive with at least 4 GB of free space. We recommend using the RE-USB-4G-S flash drive.

Note

USB flash drives used with the QFX Series device must support USB 2.0 or later.
