QFX10002 Management Cable Specifications and Pinouts

 

Cable Specifications for Console and Management Connections for the QFX Series

Table 1 lists the specifications for the cables that connect the QFX Series switch to a management device.

Note

The QFX Series can be configured with SFP management ports that support 1000BASE-SX transceivers. See the Hardware Compatibility Tool for more on the fiber-optic cables required for use with these transceivers.

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 desktop PC does not have a DB-9 plug connector 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.

RJ-45 to DB-9 Serial Port Adapter Pinout Information

The console port 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 4 provides the pinout information for the RJ-45 to DB-9 serial port 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.
