Fast Ethernet

The Fast Ethernet ports:

  • Consist of eight fixed ports
  • Are labeled as port 0/0 to port 0/7 on the front panel
  • Provide link speeds of 10/100 Mbps
  • Operate in full-duplex and half-duplex modes
  • Support flow control
  • Support autonegotiation
  • Support autosensing

The Fast Ethernet ports can be used:

  • To provide LAN connectivity to hubs, switches, local servers, and workstations.
  • To forward incoming data packets to the device.
  • To receive outgoing data packets from the device.

Universal Serial Bus (USB)

The USB port:

  • Consists of one port
  • Supports the following modes:
    • Full-speed
    • High-speed
  • Complies with USB revision 2.0

The USB port can be used:

  • To support a USB storage device that functions as a secondary boot device in case of internal flash memory device failure on startup (if the USB storage device is installed and configured).

    Note: You must install and configure the USB storage device on the USB port to use it as a secondary boot device. Additionally, the USB device must have Junos OS installed.

  • To provide the USB interfaces that are used to communicate with many types of USB storage devices supported by Juniper Networks.


The console port:

  • Consists of one port
  • Uses an RJ-45 serial cable connector
  • Supports the RS-232 (EIA-232) standard

The console port can be used:

  • To provide the console interface.
  • To function as a management port for logging in to a device directly.
  • To configure the device using the CLI.

Integrated VDSL2 interface

The VDSL2 port:

  • Consists of one port
  • Uses an RJ-11 connector for VDSL/ADSL-POTS
  • Uses an RJ-45 connector for VDSL/ADSL-ISDN

The VDSL2 port can be used to provide LAN and WAN functionality, along with connectivity to various media types.

3G USB modem

The 3G-WAN USB port on the rear side uses a USB modem extension cable to support the external 3G USB modem.

The 3G USB modem provides wireless connectivity.
