Interface Type

Specifications

Description

Gigabit Ethernet

  • Consist of two fixed ports

  • Are labeled as port 0/0 and port 0/1 on the front panel

  • Use an RJ-45 connector

  • Provide link speeds of 10/100/1000 Mbps

  • Operate in full-duplex and half-duplex modes

  • Support flow control

  • Support autonegotiation and autosensing

Both Gigabit Ethernet ports support Power over Ethernet on the PoE models of the SRX210 Services Gateway.

The Gigabit Ethernet ports can be used as follows:

  • To function as front-end network ports

  • To provide LAN and WAN connectivity to hubs, switches, local servers, and workstations

  • To forward incoming data packets to the device

  • To receive outgoing data packets from the device

  • To connect power devices to receive network connectivity and electric power (PoE functionality) (For the PoE model of the SRX210 Services Gateway)

Fast Ethernet

  • Consist of six fixed ports

  • Are labeled as port 0/2 to port 0/7 on the front panel

  • Provide link speeds of 10/100 Mbps

  • Operate in full-duplex and half-duplex modes

The first two Fast Ethernet ports support Power over Ethernet on the SRX210 Services Gateway (PoE version).

The Fast Ethernet ports can be used as follows:

  • 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

  • To connect power devices to receive network connectivity and electric power (PoE functionality) (For the PoE model of the SRX210 Services Gateway)

Universal Serial Bus (USB)

  • Consist of two ports

  • Function in full speed and high speed

  • Are compliant with USB revision 2.0

The USB ports can be used as follows:

  • To support a USB storage device that functions as a secondary boot device in case of the internal flash 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 secondary boot device. Also, the USB device must have Junos installed.

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

Contact your Juniper Networks customer service representative for more information.

Console

  • Consists of one port

  • Uses an RJ-45 serial cable connector

  • Supports the RS-232 (EIA-232) standard

The console port can be used as follows:

  • To provide the console interface

  • To function as a management port to log into a device directly

  • To configure the device using the CLI

Mini-Physical Interface Module (Mini-PIM)

Consists of one slot for a Mini-PIM

The Mini-PIM slot can be used to provide LAN and WAN functionality along with connectivity to various media types.

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

Caution

If you face a problem running a Juniper Networks device that uses a third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.
