Connecting an EX4300 Switch to a Management Console Using the Mini-USB Type-B Console Port

You can configure and manage EX4300 switches by using the RJ-45 console port or the Mini-USB Type-B console port. However, the console input will be active only on one port at a time—only one port will be set active at a time.

By default, the RJ-45 port is set as an active console port and the Mini-USB Type-B port is the passive console port. For information about configuring the console port type, see Configuring the Console Port Type (CLI Procedure).

If your laptop or PC does not have a DB-9 male connector pin or RJ-45 connector pin, you can connect your laptop or PC directly to an EX4300 switch by using a mini-USB cable that has a Standard-A USB connector on one end and a Mini-USB Type-B (5 pin) connector on the other end.

This section describes the process of connecting an EX4300 switch to the management console by using the Mini-USB Type-B console port.

For information about configuring and managing an EX4300 switch by using the RJ-45 console port, see Connecting a Switch to a Management Console.

Before you begin connecting an EX4300 switch by using Mini-USB Type-B console port:

  • Ensure that the USB to Serial driver is installed on the host machine. You can download the driver from https://webdownload.juniper.net/swdl/dl/secure/site/1/record/5029.html .
  • Ensure that the hyper terminal properties of the console server or laptop are set as follows:
    • Baud rate—9600
    • Flow control—None
    • Data—8
    • Parity—None
    • Stop bits—1
    • DCD state—Disregard

Ensure that you have the following parts and tools available:

  • 1 mini-USB cable with Standard-A and Mini-USB Type- B (5-pin) connectors (not provided).

To connect the switch to the console by using Mini-USB Type-B console port:

  1. Connect the Standard-A connector of the mini-USB cable to the host machine (PC or Laptop).
  2. Connect the Mini-USB Type-B (5-pin) connector of the mini-USB cable to the Mini-USB Type-B console port (labeled CON2) on the switch.
  3. Set the Mini-USB Type-B console port as the active console port by using the command port-type.
    For information about configuring the console port type, see Configuring the Console Port Type (CLI Procedure).
  4. Reboot the switch.

After the connection is established, the Mini-USB Type-B becomes the active console port. The host machine connected to the Mini-USB Type-B console port displays log messages and lets you control switch functionality through it.
