Connect the MX301 to External Devices

This topic guides you on how to connect your MX301 to external mangement or timing devices.

You can monitor and manage the MX301 by using a dedicated management channel. Use the management port to connect your device to the management device.

You can also connect the MX301 to external clocking and timing devices.

Connect the MX301 to a Network for Out-of-Band Management

Ensure that you have an Ethernet cable that has an RJ-45 connector at each end.

To connect a device to a network for out-of-band management:

  1. Wrap and fasten one end of an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the other end of the strap to one of the ESD points on the chassis.
  2. Connect one end of the Ethernet cable to the management port on the device.
  3. Connect the other end of the cable to the management device.

Connect the MX301 to a Management Console Using an RJ-45 Connector

Ensure that you have an Ethernet cable that has an RJ-45 connector at either end. You will also need the appropriate adapter (not provided) depending upon your console server or management console.

You can separately order the following adapters from Juniper Networks:

  • 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)

Note:

If you want to use the 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.

To connect the device to a management console:

  1. Wrap and fasten one end of an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the other end of the strap to one of the ESD points on the chassis.
  2. Connect one end of the Ethernet cable to the console port on the device.
  3. Connect the other end of the cable to the console server or PC.

Connect Your Device to a Management Console Using a Mini USB-B Connector

Ensure that you have a USB cable that has a mini USB-B connector at one end and a standard USB-A connector at the other. You will also need the appropriate adapter (not provided) depending upon your console server or management console.

Ensure that the USB-to-serial driver is installed on the host machine.

By default, the RJ-45 is the active console port. You must configure the mini USB-B console port before using it. Set the HyperTerminal properties of the console server or management console as follows:

  • Baud rate—9600

  • Flow control—None

  • Data—8

  • Parity—None

  • Stop bits—1

  • DCD state—Disregard

To connect the device to a management console:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Connect the mini USB-B connector of the USB cable to the console port on the device.
  3. Connect the standard USB-A connector of the cable to the console server or management console.

  4. Use the set system ports auxiliary port-type mini-usb command to enable logging in to the switch by using the mini USB-B console port.
  5. Reboot the switch. The boot logs and the login prompt appear on the console connected to the mini USB-B port.

Connect Your Device to a Management Console Using a USB-C Connector

Ensure that you have a USB cable that has a USB-C connector at either end. You will also need the appropriate adapter (not provided) depending upon your console server or management console.

Ensure that the USB-to-serial driver is installed on the host machine.

By default, the RJ-45 is the active console port. You must configure the USB-C console port before using it. Set the HyperTerminal properties of the console server or management console as follows:

  • Baud rate—9600

  • Flow control—None

  • Data—8

  • Parity—None

  • Stop bits—1

  • DCD state—Disregard

To connect the device to a management console:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Connect one end of the USB cable to the console port on the device.
  3. Connect the other end of the cable to the console server or management console.

  4. Use the set system ports auxiliary type ansi command to enable logging in to the switch by using the USB-C console port.
  5. Use the request system boot-console auxiliary command to see the boot logs on the console connected to the USB-C port.
    Note that only the Junos OS boot logs will be visible on the USB Type-C console.
  6. Reboot the switch. The boot logs and the login prompt appear on the console connected to the USB-C port.

Connect the MX301 to External Clocking and Timing Devices

Connect 1-PPS and 10-MHz Timing Devices

Your device has GPS clock ports that you can use to connect it to a 1-PPS and 10-MHz timing device. These ports require 2x1 DIN 1.0/2.3 latching plug connectors.

You can configure your device as a timing primary device or a client device. As a timing primary device, the device receives inputs from the timing device through the input ports and sends outputs to a client device through the output ports. As a timing client device, the device receives inputs from the timing device through the input ports.

To connect your device to a 1-PPS and 10-MHz timing device:

  1. If your device is a timing client device, connect one end of the 2x1 DIN 1.0/2.3 cables to the input ports on your device.

    If your device is a timing primary device, connect it to a client device by using the output ports.

    Note:

    Ensure that you use a cable of 3 m or less.

    Ensure that the timing device supports an input or output impedance of 50 ohms, and supports input and output voltage levels that comply with ITU G.703. The timing device inputs must be 5 V tolerant.
  2. Connect the other end of the cables to the 1-PPS and 10-MHz connectors on the timing device.

Connect the MX301 to a Time-of-Day Device

You can use the time-of-day (ToD) port on your device to connect it to a ToD timing device.

To connect your device to a ToD timing device:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis.
  2. Plug one end of an RJ-45 cable into the ToD port.
    Note:

    Ensure that you use a cable of 6 meters or less in length.
  3. Plug the other end of the RJ-45 cable into the ToD timing device.
  4. Configure the port.
