QFX5130 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 small form-factor pluggable (SFP) management ports that support 1000BASE-SX transceivers. QFX5130 switches come with a RJ-45 management port, and support 10-Gbps speed. See the Hardware Compatibility Tool for more information about the fiber-optic cables required for use with these transceivers.

Table 1: Cable Specifications for Console and Management Connections for the QFX Series
Port on QFX Series Device	Cable Specification	Maximum Length	Device Receptacle
Console port	RS-232 (EIA-232) serial cable	7 feet (2.13 meters)	RJ-45
Management port	Category 5 cable or equivalent suitable for 1000BASE-T operation	328 feet (100 meters)	RJ-45

Note:

We no longer include the RJ-45 console cable with the DB-9 adapter as part of the device package. If the console cable and adapter are not included in your device package, or if you need a different type of adapter, you can order the following separately:

RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)
RJ-45 to USB-A adapter (JNP-CBL-RJ45-USBA)
RJ-45 to USB-C adapter (JNP-CBL-RJ45-USBC)

If you want to use RJ-45 to USB-A or RJ-45 to USB-C adapter you must have X64 (64-Bit) Virtual COM port (VCP) driver installed on your PC. See, https://ftdichip.com/drivers/vcp-drivers/ to download the driver.

Console Port Connector Pinouts for the QFX Series

The console port (labeled CON or CONSOLE) 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. You can also use a RJ45 to USB 2.0 Type-A cable and a RJ45 to USB 2.0 Type-C cable.

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 QFX Series device, use a combination of an RJ-45 to DB-9 adapter and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.

Note:

We no longer include the RJ-45 console cable with the DB-9 adapter as part of the device package. If the console cable and adapter are not included in your device package, or if you need a different type of adapter, you can order the following separately:

RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)
RJ-45 to USB-A adapter (JNP-CBL-RJ45-USBA)
RJ-45 to USB-C adapter (JNP-CBL-RJ45-USBC)

If you want to use RJ-45 to USB-A or RJ-45 to USB-C adapter you must have X64 (64-Bit) Virtual COM port (VCP) driver installed on your PC. See, https://ftdichip.com/drivers/vcp-drivers/ to download the driver.

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.

Note:

To access the pinhole reset without any hindrance, you must use a USB drive with a maximum width of 16.5 mm. For reference, SanDisk Cruzer Force, HP v207 USB drives.
