Gigabit Ethernet

• Consist of two fixed ports
• Are labeled as port ge–0/0/0 and port ge–0/0/1 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 and media gateway 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 and media gateway model of the SRX210 Services Gateway)

Fast Ethernet

• Consist of six fixed ports
• Are labeled as port fe–0/0/2 to port fe–0/0/7 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 and media gateway 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 and media gateway 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

Foreign Exchange Subscriber (FXS) interface

• Consist of two ports
• Use an RJ-11 connector

The FXS port can be used as follows:

• To provide an interface to connect analog phones, fax machines, or similar devices
• To supply battery power, ringing voltage, dial tone, and so on to the station

Note: There is a hardware relay between the built-in FXO1 interface and the FXS2 interface. The relay automatically connects the FXS2 port and the FXO1 port in the event of a power failure.

Foreign Exchange Office (FXO) interface

• Consist of two ports
• Use an RJ-11 connector

The FXO port can be used to provide direct connection to the telephone exchange or Public Switched Telephone Networks (PSTN) central office

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.

Note: We strongly recommend that only transceivers provided by Juniper Networks be used on an SRX210 Services Gateway. We cannot guarantee that the interface module will operate correctly if third-party transceivers are used. Contact Juniper Networks for the correct transceiver part number for your device.
