The Network Processing I/O card (NP-IOC) SRX1K3K-NP-2XGE-SFPP 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.
