Connecting the EX3400 to External Devices

Connect a Device to a Network for Out-of-Band Management

Ensure that you have an Ethernet cable that has an RJ-45 connector at either end. Figure 1 shows the RJ-45 connector of the Ethernet cable.

You can monitor and manage these devices by using a dedicated management channel. Each device has a management port to which you can connect an Ethernet cable with an RJ-45 connector. Use the management port to connect the device to the management device.

To connect a device to a network for out-of-band management (see Figure 2):

  1. Connect one end of the Ethernet cable to the management port on the device.
  2. Connect the other end of the Ethernet cable to the management device.

Connect a Device 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 and an RJ-45-to-DB-9 serial port adapter.

Figure 3 shows the RJ-45 connector on the Ethernet cable.

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.
Note:

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 directly to the 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.

You can configure and manage your network devices using a dedicated management channel. Each device has a console port that you can connect to using an Ethernet cable with an RJ-45 connector. Use the console port to connect the device to the console server or management console. The console port accepts a cable that has an RJ-45 connector.

To connect the device to a management console (see Figure 4 and Figure 5):

  1. Connect one end of the Ethernet cable to the console port (labeled CON, CONSOLE, or CON1) on the device.
  2. Connect the other end of the Ethernet cable to the console server (see Figure 4) or management console (see Figure 5).

Connect an EX Series Switch to a Management Console Using the Mini-USB Type-B Console Port

Before You Begin

Before you connect the switch using the Mini-USB Type-B console port:

  • Ensure that the USB to Serial driver is installed on the host machine.

  • Ensure that the HyperTerminal 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

You will need the following parts and tools:

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

EX2200-C, EX2300, EX2300-C , EX3400, EX4300, and EX4550 switches, except EX2300-24MP and EX2300-48MP models, have two console ports: an RJ-45 console port that accepts a cable with an RJ-45 connector and a Mini-USB Type-B console port that accepts a cable with a Mini-USB Type-B plug (5-pin) connector. You can configure and manage the switch using the RJ-45 console port or the Mini-USB Type-B console port. On EX2200-C and EX4550 switches, only one console port is active at a time and the console input is active only on that port. On EX2300, EX2300-C, EX3400, and EX4300 switches, both the RJ-45 console port and the Mini-USB Type-B console port can be active at the same time.

Note:

EX2300-24MP and EX2300-48MP models only have an RJ-45 console port.

By default, the RJ-45 console port is the active port. If your laptop or PC does not have a DB-9 plug connector pin or RJ-45 connector pin, you can connect your laptop or PC directly to the switch 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. You must first configure the Mini-USB Type-B console port as the active port before you can use it to connect to the switch.

This topic describes the procedure to connect EX2200-C, EX2300, EX2300-C, EX3400, EX4300, and EX4550 switches to the management console using the Mini-USB Type-B console port.

For information about configuring and managing an EX Series switch using the RJ-45 console port, see Connect a Device to a Management Console Using an RJ-45 Connector.

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

  1. Connect the host machine to the device directly using the active console port or remotely using the management interface. To connect using the active console port, which is the RJ-45 console port by default, see Connect a Device to a Management Console Using an RJ-45 Connector.
  2. Connect the Standard-A connector of the mini-USB cable to the host machine (PC or laptop).
  3. Connect the Mini-USB Type-B (5-pin) connector of the mini-USB cable to the Mini-USB Type-B console port (labeled CON) on the switch.
  4. 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. Set the Mini-USB Type-B console port as the active console port using the port-type command. See Configuring the Console Port Type (CLI Procedure).
  5. Reboot the switch. The boot log appears on the activated console.

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 you can control switch functionality through it. On EX2300, EX2300-C, EX3400, and EX4300 switches, both the Mini-USB Type-B and RJ-45 console ports are now active. On EX2200-C and EX4550 switches, the Mini-USB Type-B console port is active and the RJ-45 console port is passive.
