The SRX3K-2XGE-XFP (Figure 1) IOC adds two ports for 10-Gigabit Ethernet traffic from fiber interface media. It is inserted horizontally into the midplane of the services gateway to communicate with the Switch Fabric Board (SFB) and to receive power. To use fiber interface media, install 10-Gigabit small form-factor pluggable (XFP) transceivers on the desired ports. LEDs on the faceplate of the IOC indicate port status and connectivity (see Table 15 on page 27). Ports are numbered from left to right, 0-1.

Cables and connectors

Two XFP sockets for Ethernet transceivers

Supported XFP transceivers:

10GBASE-ER (model numbers SRX-XFP-10GE-ER and SRX-XFP-10GE-ER-ET )

10GBASE-LR (model numbers SRX-XFP-10GE-LR and SRX-XFP-10GE-LR-ET

10GBASE-SR (model numbers SRX-XFP-10GE-SR and SRX-XFP-10GE-SR-ET )


ONLINE Button–The ONLINE button on the IOC front panel does not perform any function.

Supported Slots

  • SRX1400: Front slot labeled 2

  • SRX3400: Front slots labeled 1 through 4 (except as noted below)

  • SRX3600: Front slots labeled 1 through 6 (except as noted below)

Note: When an SRX3400 or SRX3600 Services Gateway is in the Express Path (formerly known as Services Offload) mode supported in Junos OS release 12.1X44-D10 and later, IOCs are only supported in front panel slots 1 through 3. See the Junos OS documentation for more information about Express Path mode.


IOCs are cold-swap-only modules. You must power-off the services gateway before removing, replacing, or adding IOCs.


SERVICE LED, one bicolor

  • Off–The IOC is administratively disabled, butmapped to the NPC.

  • Green–The IOC is mapped to the NPC and is available to carry Ethernet traffic.

  • Amber–The IOC is not mapped to the NPC and is not available to carry Ethernet traffic.

OK/FAIL LED, one bicolor

  • Off–One or more of the following conditions apply:

    • The services gateway is not powered on.

    • The services gateway is still in the process of either booting or shutting down.

    • The services gateway is not configured for chassis clustering.

  • Steady Green–The services gateway is configured for chassis clustering, and the SCM is operating normally.

  • Blinking Green–The SCM is initializing (preparing to come online) or is preparing to go offline.

  • Red–The SCM has failed and is not operating normally.
