Network Processing I/O Card SRX1K3K-NP-2XGE-SFPP


The Network Processing I/O card (NP-IOC) SRX1K3K-NP-2XGE-SFPP (Figure 1) is an IOC that includes its own Network Processing Unit (NPU), so that traffic traversing the NP-IOC does not have to also traverse the services gateway bus to a remote NPC. This feature makes the NP-IOC well-suited to low-latency applications . It is inserted horizontally into the midplane of the services gateway to communicate with the SFB and to receive power. To use fiber interface media, install enhanced small form-factor pluggable (SFP+) transceivers on the desired ports. LEDs on the faceplate of the NP-IOC indicate port status and connectivity. The SFP+ ports are numbered from left to right, 0-1.


For detailed information about supported transceivers, see the SRX Series Services Gateway Transceiver Guide   at

Supported Slots

  • SRX1400: Front slot labeled 2

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


SERVICE LED, one bicolor

  • Off–The NP-IOC is administratively disabled.

  • Green–The NP-IOC is available to carry Ethernet traffic.

  • Amber–The NP-IOC 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 NP-IOC is offline. To bring the NP-IOC online, press the ONLINE button.

  • Red–The NP-IOC has failed and is not operating normally.
