Interface Type

Description

Usage

Gigabit Ethernet

  • 16 ports, labeled 0/0 through 0/15, built into the chassis front panel
  • Provide link speeds of 10/100/1000 Mbps
  • Operate in full-duplex and half-duplex modes

Note: On the PoE models of the SRX240 Services Gateway, all 16 Gigabit Ethernet ports support PoE.

Function as front-end network ports and provide LAN and WAN connectivity to hubs, switches, local servers, and workstations.

Universal Serial Bus (USB)

  • Two ports labeled, usb 0 and usb 1, built into the chassis front panel
  • Function in the following modes:
    • Full speed
    • High speed
  • Compliant with USB revision 2.0
  • Support a USB storage device that functions as a secondary boot device in case of internal flash failure on startup.

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

  • Provide the USB interfaces that are used to communicate with the various types of Juniper Networks-supported USB storage devices.

    Contact a customer service representative for more information.

Console

  • One port built into the chassis front panel
  • Uses an RJ-45 serial cable connector
  • Supports the RS-232 (EIA-232) standard
  • Functions as a management port using which you can log in to the services gateway directly.
  • Provides the interface to configure the services gateway using the CLI.

Mini-PIM slots

  • Four slots built into the chassis front panel
  • Mini-PIMs can be plugged directly into the slots

Provide LAN and WAN functionality along with connectivity to various media types.

For more information about Mini-PIMs, see the SRX Series Services Gateways for the Branch Physical Interface Modules Hardware Guide.

Note: We strongly recommend that only transceivers provided by Juniper Networks be used on an SRX240 Services Gateway. We cannot guarantee that the interface module will operate correctly if third-party transceivers are used. Please contact Juniper Networks for the correct transceiver part number for your device.
