Mini-USB Type-B Console Port Specifications for an NFX150 Device

NFX150 Device has two: an RJ-45 port, and a Mini-USB port.

By default, the RJ-45 port is set as the active console port. It can display all the early boot and low-level message output and you can access the device through this port in the debugger prompt.

The Mini-USB port is the passive console port. You can change the status of the port to active or passive using the port-type configuration statement. See Configuring the Console Port Type (CLI Procedure).

The Mini-USB console port uses a Mini-B plug (5-pin) connector to connect to a console management device. The default baud rate for the console port is 9600 baud.

Table 2 provides the pinout information of the Mini-USB Type-B console port.

Console Port Connector Pinouts for NFX150 Devices

The console port (labeled CON) 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. An RJ-45 cable and RJ-45 to DB-9 adapter are supplied with the NFX150 device.

Note

If your laptop or PC does not have a DB-9 male connector pin and you want to connect your laptop or PC directly to an NFX150 device, use a combination of the RJ-45 cable and RJ-45 to DB-9 adapter supplied with the device and a USB to DB-9 male adapter. You must provide the USB to DB-9 male adapter.

USB Port Specifications for an NFX150 Device

The following Juniper Networks USB flash drives have been tested and are officially supported for the USB port in the NFX150 devices:

  • RE-USB-1G-S—1-gigabyte (GB) USB flash drive

  • RE-USB-2G-S—2-GB USB flash drive

  • RE-USB-4G-S—4-GB USB flash drive

Caution

Any USB memory product not listed as supported for the NFX150 device 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 NFX150 device. Failure to do so could expose your device to unpredictable behavior.

Note

Executing the request system snapshot CLI command on a NFX150 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 NFX150 device must support USB 2.0 or later.

Management Port Connector Pinout Information for an NFX150 Device

The 1000BASE-T RJ-45 management port on an NFX150 device uses an RJ-45 connector to connect to a management device for out-of-band management.

Table 4 provides the pinout information of the RJ-45 management port connector.

Network Port Connector Pinout Information for an NFX150 Device

A network port on an NFX150 device uses an RJ-45 connector to connect to a device.

The port uses an autosensing RJ-45 connector to support a 10/100/1000Base-T connection. Two LEDs on the port indicate link/activity on the port and the port status. See LED Details of an NFX150 Device.

Table 5 provides the pinout information for the RJ-45 connector. An RJ-45 cable, with a connector attached, is supplied with the switch.

RJ-45 to DB-9 Serial Port Adapter Pinout Information for an NFX150 Device

The console port is an RS-232 serial interface that uses an RJ-45 connector to connect to a management device such as a PC or a laptop. If your laptop or PC does not have a DB-9 male connector pin and you want to connect your laptop or PC to an NFX150 device, use a combination of the RJ-45 to DB-9 female adapter supplied with the switch along with a USB to DB-9 male adapter.
