Connect the EX4100-H Switch 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.

You can monitor and manage a network device, such as a router or a switch, 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:

  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.

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:

  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 3) or management console (see Figure 4).

Connect an EX4100-H Switch to a Management Console Using the USB Type-C Console Port

Before You Begin

Before you connect the switch using the USB Type-C 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:

  • One USB cable with USB Type-C connectors at both ends (not provided).

  • (If your laptop or desktop PC does not have a USB Type-C port) One USB Type-A to USB Type-C converter cable (not provided).

EX4100-H switches have two console ports:

  • An RJ-45 console port on the rear panel that accepts a cable with an RJ-45 connector

  • A USB Type-C console port on the front panel that accepts a USB cable with a USB Type-C connector

You can log in to the switch and configure and manage the switch by using either of the console ports. The RJ-45 console port is enabled by default. However, you must configure the USB Type-C console port before you can use it to connect to the switch.

In this topic, you learn how to connect EX4100-H switches to the management console using the USB Type-C console port.

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

  1. Connect the host machine to the device directly. You can use the active console port or use the management interface to connect remotely.
  2. Connect one end of the USB cable to the USB Type-C or Type-A port your PC or laptop.
  3. Connect the other end of the USB cable to the USB Type-C console port on the front panel switch.
  4. Use the set system ports auxiliary configuration command to enable login (to the switch) using the USB Type-C console port.
  5. Use the request system boot-console auxiliary command to see the boot logs on the console connected to the USB Type-C port.
  6. Reboot the switch. The boot logs and the login prompt appear on the console connected to the USB Type-C port.
